The Top 10 Cannabis Grinders in 2020

A good cannabis grinder goes a long way. Because, without a decent grinder, you risk stuffing your rolling paper with large chunks of marijuana that burn unevenly and ruin your experience. Not to mention the fact that you risk wasting a lot of product using bad marijuana grinders.

Good cannabis grinders cut through the dry herb and chop it up to a small, flavourful and smokable size. They spare you from the time-consuming process of picking apart your herb by hand, and they can store enough herb to last for multiple smoking sessions.

There are plenty of cannabis grinders out there, but only the best marijuana grinders made it on our list. Without further ado, let’s take a look at the top 10 cannabis grinders in 2020.

The best cannabis grinders in 2020

1. HØJ KLIP

The HØJ KLIP is a cannabis grinder Strain Insider featured in the past. But the truth is that we simply love this marijuana grinder and couldn’t miss out on the opportunity of including it in this top 10 article.

What really makes the HØJ KLIP stand out is its durable yet sleek construction. The KLIP is made out of aluminium, stainless steel, polished brass and rare-earth magnets. Further, its design makes it look more like a futuristic gadget than a cannabis grinder. Despite its compact size, this marijuana grinder is heavy and stable.

The HØJ KLIP uses custom-made dual-blades to slice through the product, and the result is a herb that’s small and has a fluffy consistency, making it easier to burn. The grinder’s design allows almost every microgram of herb to drop into its bottom chamber, enabling you to get the most out of your product.

Highlights: Specially designed for dry cannabis herbs. Minimizes product loss.

2. ZAM Grinder

The ZAM Grinder is a new product that’s specially designed with cannabis consumers in mind. This small and compact marijuana grinder is air- and water-tight, allowing you to keep your product safe and dry even in unexpected circumstances.

One of the things we liked about the ZAM cannabis grinder is that its design enables users to hold both its body and its rotating lid securely, making the grinding process easier. The grinder has a modular design, so you can remove the pieces you don’t use to make the grinder fit into your pockets or purse.

The ZAM’s teeth are long, and its grinding compartment is deep, allowing you to grind more product at once. With no less than 14 teeth, the grinder will chop up your herb to a fine consistency in a matter of moments.

Highlights: Air- and water-tight. Capable of keeping your herb in top condition for a long time.

3. Golden Gate Grinders Herb Grinder

The Golden Gate Grinders cannabis grinder is a short and robust model that’s made out of high-quality aluminium. This grinder is durable and comes with a scratch-resistant finish that will keep it looking like new for a long time.

This marijuana grinder is well designed, and its teeth cut through the herb without ripping or shredding it, and without leaving large chunks behind. Even though it’s short, the grinder’s centre of gravity is nicely balanced, allowing you to turn the lid smoothly and without toppling the entire thing.

One of the things we liked about this model is that it comes with a good kief screen. Using the grinder on a regular basis can help you collect a lot of kief over time.

Highlights: The grinder’s kief screen acts like a kief magnet. It collects a LOT of kief in the grinding process.

4. Kozo Grinders Herb Grinder

The Kozo Grinders cannabis grinder has a special design that makes grinding easy and effective. This short and stocky marijuana grinder is perfect for those who don’t like to grind their product for ages before it’s small enough to smoke.

One of the great things about the Kozo cannabis grinder is that it comes with some really SHARP teeth. Its teeth have good, sharp edges that will chop up your herb evenly, ensuring a nice and even burn.

The knurling on the grinder’s edges makes it easy to grip and work with, and the entire grinding process is fast. The bottom is stable and pretty tall, enabling you to unscrew it without spilling the herb.

Highlights: Comes in multiple colours so you can choose one that matches your preferences.

5. iRainy Herb Grinder

The iRainy cannabis grinder is one of the cheapest models that made our list. This small marijuana grinder has a modular design made out of five pieces that create four different chambers. The modular design allows you to use the grinder with all five pieces in place or even without some of them.

However, you should keep in mind that its two different mesh screens allow only the finest, fluffiest herb to reach the bottom chamber and, ultimately, the rolling paper, so you should use both at the same time.

This cannabis grinder is made out of a zinc alloy, which makes it pretty lightweight. But, despite its weight, this model is pretty durable and should last for a very long time.

Highlights: Modular design and spacious collecting chamber.

6. Mendo Mulcher

The Mendo Mulcher cannabis grinder is a small 2-piece model that’s perfect for those who want to keep their marijuana grinder close when they’re on the go. Even though this is one of the smallest grinders that made our list, you shouldn’t let its small size fool you.

The grinder is made out of aircraft-grade aluminium and has a good weight for its size. The extra-grippy construction ensures that your hand won’t slip and you won’t drop the cannabis grinder while you work on your herb.

This model will cut dry herb to small, even pieces. However, it doesn’t have a mesh filter, so it’s not recommended for those who want to separate the kief.

Highlights: Small and durable.

7. Aerospaced Grinder

The Aerospaced cannabis grinder is a hand-cranked model that enables you to see what’s happening to your herb while you work on it. This model uses a hand crank to operate a set of blades that cut up your dry herb to small pieces. The hand crank also makes the grinding process extremely easy and basically effortless.

This model has a clear lid that enables you to see the grinding operation, making the entire experience more pleasant. You can operate the crank clockwise or counterclockwise, which is great when you notice that a large chunk of herb is caught between the blades. This enables you to ensure that every single bit of your herb is finely chopped, no matter how large it is when you start the grinding process.

Highlights: Hand crank for easy operation. See-through lid that enables you to observe the herb being ground.

8. Kannastör

The Kannastör marijuana grinder is an awesome-looking model that has a modular design. This cannabis grinder comes with two removable screens and two interchangeable graters, allowing you to select the coarseness of your final product — fine or medium.

This model comes with eight separate pieces. But, thanks to its modular design, you can quickly take this grinder apart and reconstruct it with only the pieces that you want. The grinder is made out of high-quality aluminium and has a well-balanced centre of gravity.

One of the things that make this model stand out is that its fine grind is VERY fine. It produces extremely fluffy, evenly-cut dry herb.

Highlights: Modular design. Interchangeable graters. Very fine grind.

9. Anpro Premium Grinder

The Anpro Premium cannabis grinder is another budget-friendly model that made our list. This model is made out of aluminium and has an electroplated finish that won’t peel off no matter how poorly you treat it.

This model is short and stocky, but it’s wide enough to store a lot of herb. The grinder’s lid is magnetised, and the bottom compartment is tall, so you won’t spill any of your product in the grinding process.

Besides its low price, one of the other things that stand out about this product is that it’s super easy to maintain. Thanks to its practical finish, you can clean the grinder with water without worrying about rust.

Highlights: Durable finish. Easy to maintain.

10. Golden Bell Grinders Herb Grinder

The Golden Bell Grinders cannabis grinder has a nice design and a lovely finish. Created using heavy-duty zinc, this model is sturdy but lightweight. The marijuana grinder comes with four pieces that create three chambers. Its mesh screen allows only the smallest bits of herb to reach the storing chamber, so you can rest assured that all your product will burn evenly.

This model uses sharp teeth to grind your herb to fine particles. The teeth can easily cut through cannabis, and, thanks to the Poly O-Ring, the grinding process is smooth and fast.

The Golden Bell Grinders cannabis grinder is small, tough and reliable. Also, the manufacturing company is so confident in the grinder’s quality that it offers a lifetime warranty.

Highlights: Lifetime warranty. Smooth grinding.

Looking for a grinder? There are plenty of marijuana grinders out there, but only the best made our list. Here are the top 10 cannabis grinders in 2020.

The Best Weed Grinder

Updated June 21, 2018

Our budget pick, the Platinum Grinders Herb Grinder, is back in stock. We’ve moved the SharpStone V2 Grinder back to the Competition.

Share this review

After more than 20 hours considering 32 grinders and testing 12 of them, we found that the Santa Cruz Shredder Medium 3-Piece grinds smoothly and evenly, producing results that work equally well whether destined for a pipe, vaporizer, or recipe. This grinder’s uniquely shaped teeth make quick work of the densest flowers and should stay sharp for years. Its extra-deep collection chamber holds more material than the competition and is easy to empty.

Our pick

Santa Cruz Shredder Medium 3-Piece

Sharp teeth, ample collection chamber

This simple three-piece model offers reliably smooth grinding thanks to durable, sharp, uniquely shaped teeth. Its collection chamber is the largest of any model we tested, and has rounded sides that make it easy to empty.

Buying Options

*At the time of publishing, the price was $50 .

In our tests, the four-pointed teeth on the Santa Cruz Shredder Medium 3-Piece grinder quickly and easily broke apart even our stickiest, most closely packed flowers. The three-piece model we recommend is easy to empty little by little thanks to its rounded bottom—far less messy than dumping a grinder out to get at anything stuck in the corners. The pieces of this grinder easily thread together and its top glides smoothly as you twist it. “If I could only have one grinder I would definitely go with a Santa Cruz Shredder,” Buzz of VaporizerWizard.com told us in an email.

Upgrade pick

Kannastör Gr8tr V2

For the finest, most consistent results

This model produced the fluffiest and finest results in our tests—a plus for many vaporizers. Its bonus storage compartment and an optional plate for coarser grinds are unique extras worth the added cost, but not necessary for everyone.

Buying Options

*At the time of publishing, the price was $75 .

The small, sharp teeth inside the Kannastör Gr8tr V2 tore through cannabis smoothly without binding and dropped the finest and fluffiest material of any we tried into its collection chamber. That’s ideal for many vaporizers, especially conduction-based models or hybrid conduction-convection models. (If you have a convection vaporizer, you can unscrew the Kannastör’s fine-grind plate and replace it with the included coarse-grind option.) Without adding bulk, the Gr8tr V2’s topmost piece seals off an extra storage compartment that no other grinder we considered includes—a great place to store whole flowers that you plan to grind later. The extra features aren’t necessary for everyone, but if you want a premium grinder, these features make the Gr8tr V2 worth the extra money.

Budget pick

Platinum Grinders Herb Grinder

The best in its price range

Although it doesn’t feel as well-made and isn’t as smooth to use as our other picks, the Platinum Grinders Herb Grinder gets the job done better than all other inexpensive grinders we tested.

*At the time of publishing, the price was $17 .

Given the cost of cannabis and vaporizers, we think that our top picks are worth every cent. But if you can’t justify the extra cost, get the Platinum Grinders Herb Grinder instead. For about less than half the price of our top picks, the Platinum Grinders model gets the job done reasonably well. The biggest drawback to the lower-quality construction of this model is the longevity: Some Amazon customers have noted failures at weak points such as the threads or the connection of the grinding plate. A few customers noted finding metal flecks in their grinders on first use, likely remnants of the manufacturing process. We’d recommend cleaning this budget option with rubbing alcohol before using it for the first time.

The research

Why you should trust us

We’ve covered the best portable vaporizers for most people for a few years, taking input from far and wide to decide what to test. We’ve now done the same for grinders; we looked at best-selling grinders and user reviews on Amazon, read enthusiasts’ feedback on forums, and even sat through video reviews on YouTube. We also got input from two expert reviewers in the field, Bud at The Vape Critic and Buzz at VaporizerWizard.com. Both are prolific reviewers who have in the past given us feedback on the dozens of vaporizers they’ve tried. They provided valuable insights into how to get the most from any grinder.

Who this is for

Despite the rise in concentrates, waxes, edibles, and a host of prepared cannabis products, most people still buy and use regular cannabis flowers—good old-fashioned pot. And most people smoking, vaporizing, or cooking with cannabis can benefit from a grinder. With a grinder you can quickly and easily turn dense, sticky buds into material that will heat evenly and efficiently. If you partake only on occasion, an inexpensive model will do enough to make your rare indulgence all the better. But if you regularly reach for a vaporizer, the investment in a high-end weed grinder won’t seem like a stretch and will pay off in the form of more bang for your bud. Though cheap grinders sometimes break, a high-quality grinder is an investment that should last for years.

Most people who casually reach for a vaporizer from time to time probably don’t have much use for separating the kief—the highly potent, crystal-like dust on leaves of cannabis plants—from the rest of the material, so we didn’t focus on kief-catching features like screens.

Be sure to read about the health and legal implications of cannabis use in our guide to portable vaporizers. Just like vaporizers, grinders are legal up until you use them with an illegal substance. Then, they become paraphernalia and are subject to the corresponding laws in your jurisdiction.

How we picked and tested

We considered the top brands recommended by expert and amateur reviewers alike. We focused on medium grinders in the 2-inch-diameter range—large enough to grind herbs for multiple sessions, but not so big they take up too much space—and looked for three- and four-piece models that let ground material fall through into a collection chamber. Letting gravity do the collection work is easier and less time-consuming than picking weed from between sharp teeth (as you would need to do when using a two-piece grinder).

On Amazon, best-selling and top-rated grinders that fit our initial criteria start at just $10, but seeing the difference between inexpensive grinders and models that cost up to $100 when shopping online can be difficult. Glossing over claims about sharper teeth or better materials when staring at pictures is easy, but the difference jumps out at you when you twist a quality grinder in your hands. It threads together with ease, plus glides and grinds more smoothly. We tested 12 models that ranged in price from $6 to $85 to determine the best value for most people based on four main criteria:

No binding when grinding: Some modern cannabis strains can produce flowers with incredibly dense buds that are hard to grind. The best grinders have teeth that will slice through these buds instead of binding while you try to force them through. The shape, sharpness, and number of teeth all contribute to this, but you can’t easily see what works best based on individual user reviews. During testing, we paid close attention to which design details resulted in easy, thorough grinds.

Easy to empty: A good three- or four-piece grinder should let most of your material fall through the holes between the teeth and into the collection chamber. It’s no fun to sit around picking tiny leafy chunks out from between sharp metal teeth. Yes, a knock or two will normally dislodge stuck buds, but sticky cannabis strains can stubbornly cling to tiny crevices. We looked for models that didn’t hold herbs hostage.

Evenness of grinds: Well-ground weed will often heat more evenly (and thus more efficiently) than uneven chunks torn by hand. Buzz at VaporizerWizard.com prefers to get a finer grind for conduction vaporizers, like models from the popular Pax line, or something a little coarser that lets air through for convection vaporizers like the Firefly. A slightly coarser grind is more flexible, though. To get a finer grind, all you need to do is give your flowers a few extra twists with the grinder upside down. That will keep it from falling through the holes into the collection tray and makes for finer material when you flip the grinder back over. Because preferences and uses vary, we focused on smooth and even grinds more than granularity in our testing.

Durability and support: A hunk of aluminum isn’t easy to damage, but accidents happen. Acrylic tops can crack and cross-threading two pieces when screwing them together can damage the threads. The pressure-fit and glued-in magnets that hold on the top grinding plate could pop out. Teeth can dull and begin to bind.

In short-term testing, we can’t replicate the type of use and abuse a grinder is likely to see over years of ownership. But in person and side by side, the varying construction quality is obvious. Some models felt cheap, made squeaks and groans when we unscrewed them, and had large, visible seams. The best models, though, felt precision-machined, with seams that disappeared from sight and would quietly glide across their threads. You can fairly assume that grinders made with care and precision should also last much longer. That said, we will monitor the performance of our picks over the long term.

If you’re going to spend more than the minimum to get a well-made grinder, having a company that will stand behind it is also nice. We noted the warranty and support options from each company, too.

Our pick: Santa Cruz Shredder Medium 3-Piece

Our pick

Santa Cruz Shredder Medium 3-Piece

Sharp teeth, ample collection chamber

This simple three-piece model offers reliably smooth grinding thanks to durable, sharp, uniquely shaped teeth. Its collection chamber is the largest of any model we tested, and has rounded sides that make it easy to empty.

Buying Options

*At the time of publishing, the price was $50 .

The Santa Cruz Shredder Medium 3-Piece uses more than two dozen uniquely shaped teeth to help it smoothly cut through dense flowers, dropping ground material with an even consistency into a huge collection chamber.

Santa Cruz Shredder grinders have a tooth shape that differs from that of every other grinder we tried: In our testing we found that its four-pointed teeth work as well as or better than the diamond-shaped teeth in most grinders. The teeth easily shredded each sample we tried, and the top grinding plate rotates so easily it almost feels like it’s floating. The grinding plate and teeth are made of the same piece of aluminum, and the metal’s anodized finish should hold up well to wear and tear. Less expensive models, like our budget pick, often have an unfinished grinding plate that won’t be as durable in the long term. The holes in the Santa Cruz Shredder’s grinding plate are an average size, and they yield a medium-coarse grind that works equally well with vaporizers, recipes, or pipes.

Each time we took the grinder apart and screwed it back together, the threads mated smoothly and never bound up like those of some of the competition.

Because the three-piece model we tried doesn’t have a pollen screen, everything falls into the massive collection chamber. As one Grasscity commenter put it, the chamber is so big that “it can hold a shit ton of weed.” At nearly an inch deep, the dish is two to three times deeper than the collection chambers on other models we looked at, and the corners and sides are nicely rounded, letting you easily pinch out what you need. Even the larger four-piece Santa Cruz Shredder models don’t have this collection chamber, so the extra capacity of our three-piece pick stands out in a crowd.

Bud at The Vape Critic also recommends a Santa Cruz Shredder grinder: “Tons of people have it and love it, and I receive virtually zero complaints,” he wrote. Buzz at VaporizerWizard.com had high praise for this grinder, too. “I use my Santa Cruz Shredder more than the rest of my grinders put together, and if I could only have one grinder I would definitely go with a Santa Cruz Shredder,” he wrote in an email.

Not only are Santa Cruz Shredders highly regarded by enthusiasts for their quality, but if the teeth ever break, the company stands behind them with a lifetime warranty.

We focused on the three-piece model without the pollen screen, but if you want to separate your kief, the four-piece model includes a screen and catcher.

Upgrade pick: Kannastör Gr8tr V2

Upgrade pick

Kannastör Gr8tr V2

For the finest, most consistent results

This model produced the fluffiest and finest results in our tests—a plus for many vaporizers. Its bonus storage compartment and an optional plate for coarser grinds are unique extras worth the added cost, but not necessary for everyone.

Buying Options

*At the time of publishing, the price was $75 .

If you would appreciate extra, dedicated storage in your grinder or the option to change the coarseness of your grind, the Kannastör Gr8tr V2 is worth the higher price to prepare your pot. The Gr8tr V2 is an update to our previous top pick, the Gr8tr. The newer model is nearly identical on the inside, and grinds just as well as the original. It also carries forward the exceptional feel of quality materials and construction we liked in the first version, adding a facelift for the exterior design. The Gr8tr’s fine, fluffy results set it apart from any other grinder we tried at any price.

The two included grinding plates are a standout feature of the Gr8tr V2. The fine-grind plate has nearly 80 holes, which are smaller than our top pick’s 15 holes. Buzz from VaporizerWizard.com told us that when he wants to maximize the vapor output on a conduction vaporizer, he likes the finer grind offered by the Magic Flight Finishing Grinder. Though we didn’t consider the Magic Flight grinder because it’s offered in only a two-piece design, the holes on the Gr8tr V2 are similarly sized. The plate in the updated Gr8tr V2 is nearly identical to that of our former top pick, the discontinued Gr8tr, so you can expect similar results. As one Reddit reviewer wrote on r/vaporents: “This grind size for me ended up being a perfect all-rounder. I didn’t feel like my convection vaporizers were going to be damaged due to too fine of a grind and my conduction vaporizers still produced very large clouds. To me it is the best of both worlds.”

If you don’t want such a fine grind, or dislike when large bits and stems get stuck in the smaller holes, you can quickly unscrew the grinding plate and replace it with the included coarser-grind plate. (The spare plate can be screwed into the top of the grinder for storage, or kept in a safe spot if you prefer to keep the grinder a bit svelter.) That extra plate has holes closer in size to those of most other grinders, and would be best for convection-based vaporizers that benefit from the extra airflow of more coarsely ground cannabis.

In addition, the Gr8tr V2 adds another unique feature: a second storage compartment in the lid. In every other grinder we tried, the only place to keep anything is in the collection chamber at the bottom. But the free-spinning magnetic top piece of the Gr8tr V2 unscrews to reveal an extra storage area, which is perfect for whole flowers. Plus, if you want something more compact on the go, the top and bottom pieces mate together into a slim storage puck.

When you open the Gr8tr V2, you can tell that Kannastör put a lot of attention into detail and quality. But if anything does go wrong, the company offers a lifetime warranty with email support.

If you’re an enthusiast who uses a variety of vaporizers and smoking accessories, you might consider spending a bit more to get the Kannastör Gr8tr V2 Solid Body w/ Stainless Easy Change Screen version. It comes with an extra piece with a mesh pollen screen for kief collection.

We spent more than 20 hours considering 32 weed grinders and testing 12. Here’s the one we picked based on its smooth, even, and versatile results.
