The best weed grinders will give you a smoother toking experience. And they’re not just for rolling joints anymore. Herb grinders are downright critical if you’re using a vaporizer.

(Vaporizers don’t use combustion, so they heat the herb’s surface area. Grinding your cannabis gives you more surface area to vaporize.)

Here are the best weed grinders available.

Our Unbiased Reviews
  1. 1. Best in Rose Gold: iRainy 5-Piece Herb Grinder with Keef Catcher

    Pros:
    • Lovely rose gold color
    • Two separate kief catchers
    • Magnetic lid
    Cons:
    • Five pieces could be a lot to keep together (after that kief-filled joint)
    • Screens could fall out after repeated use
    • Pieces could get stuck together if you over-tighten

    This is perfect if you document your cannabis wellness routine for Instagram. Especially if you want to match your grinder to your rose gold vaporizer.

    But this grinder isn’t just for boosting your influencer status. It’s a 5-piece unit with 4 separate chambers, including two different keef catchers. (Which this product description calls “pollen catchers.”) You’ll have two different ongoing keef collections: one for normal keef, and one for super-fine keef. (Kief is a part of the cannabis resin glands that’s packed with cannabinoids and terpenes.) The unit comes with a keef scraper to shovel up little heaps of it, when you’re ready for an extra helping of THC.

    Roll a super delicious joint that packs a heady, kief-filled punch! 

     

  2. 2. Best All-Around Herb Grinder: 2.5″ Grinder with Kief Catcher and Storage Chamber

    Pros:
    • Magnetic lid for quick closure
    • One-year warranty
    • Large chamber doubles as a stash box
    Cons:
    • Grinder gets stuck if bud is placed directly in the middle of the grinder
    • Can be difficult to twist
    • Can get gunked up

    This herb grinder is 2.5 inches in diameter. It grinds herb to fine, packable consistency. It has razor-sharp teeth, so it will grind even the densest (or most stem-filled) bud.

    It has an unusually large kief catcher, so if you love saving up your kief for months at a time, this is perfect for you. It comes with a kief scraper, which is kind of like a tiny shovel for spooning up that super-fine powder of cannabinoid-filled dried resin called kief.

    This design has clear plastic windows, so you can see how much herb you’ve ground up. The ground-herb chamber is also pretty large. (This is taller than some models, so even though it’s only 2.5 inches in diameter, it can store quite a bit of dried herb.)

    With a tight-fitting magnetic lid, you can feel free to take your ground herb on the go. This grinder doubles as a portable storage device. 

  3. 3. Best for Never Getting Your Grinder Mixed Up with Your Friend’s: Mandala Design 4-Piece Grinder

    Pros:
    • Beautiful mandala design
    • Micro-screen and kief chamber
    • Strong magnetic lid
    • Grinds easily
    • 14-Day Money Back Guarantee
    • Unique design means nobody will mistake your grinder for theirs
    Cons:
    • 2-inch diameter doesn't hold as much herb as some larger grinders
    • Can't grind that much herb at once
    • One reviewer found kief screen too flimsy

    This 2-inch-wide grinder doesn’t just look amazing, thanks to its polyurethane-coated mandala design. It also functions well, according to many happy customers. 

    But that design. A mandala is a spiritual symbol that represents the universe. This is perfect for anyone who finds themselves thinking about the universe after using their weed grinder. 

    It’s also made of aerospace-class aluminum, making it more lightweight than traditional zinc alloy grinders, without sacrificing durability. 

    It has textured edges for better grip. So you have greasy hands, or if you find yourself dropping metal gadgets for any other reason, this could be a nice feature. Plus the neodymium magnets keep the lid firmly attached.

    There’s a micro-screen and kief chamber, too, and an included pollen scraper.

    This isn’t the biggest grinder on the list. But it’s definitely the most beautiful. The UV-sealed mandala design is so eye-catching, you may find yourself displaying this cannabis grinder in your home, next to your crystals and your yoga mat. 

  4. 4. Best 5-Piece Herb Grinder: 9to5 Grinders 5-Piece with Removable Screen and Jar

    Pros:
    • Made from high-quality and durable materials
    • Transparent storage jar chamber
    • Can remove one chamber to make it more portable
    • Kief catcher screen is removable
    • Great customer service
    Cons:
    • Occasionally squeaks when grinding
    • Doesn’t come with instructions
    • Metal screw on kief catcher has caused minor problems for some users

    This grinder might cost more than other models, but it doesn’t skimp on quality. 9to5 Grinders makes their products from aircraft aluminum, using powerful magnets and razor-sharp diamond cutting teeth. This model has enlarged openings between the grinding and storage chamber, so you won’t grind your cannabis too finely (a common complaint with some cheaper models.)

    You can also remove the kief-sifting screen to make sure you get every last bit. It comes with a guitar pick as your kief scraper, which is kind of adorable. It also comes with a cute carrying bag.

    The ground-herb chamber is transparent, so you can always see how much you’ve ground, without opening up the unit.

    If you want to downsize this grinder to make it more compact and portable, you can remove the transparent storage jar.

    Customers also say they experience great customer service.

     

     

  5. 5. Best Cheap Herb Grinder: Golden Bell 4-Piece Grinder

    Pros:
    • Easy grinding with minimal friction
    • Includes kief catcher and mini-scraper
    • Extremely affordable
    • "Lifetime Warranty"
    Cons:
    • Ground herb chamber may be small for your needs (2 inch diameter)
    • Magnetic top may weaken over time
    • Cheaply made (obviously)

    This is made of zinc, and some users say that if you use it repeatedly for an extended period of time, some metal may wear off. Which sounds like an unpleasant situation — and unhealthy, if you don’t notice it getting mixed up with your ground herb.

    Still, nearly every customer is satisfied with the basic functionality of this device. And, everyone agrees, you can’t beat the price. Some users have noticed small design flaws, like the ground-herb chamber is pretty small, while the kief chamber is surprisingly large. Others say it can be hard to get the kief out. (One resourceful customer put a penny in the chamber to help lift out the kief.)

    Still, if you’re on a tight budget, there’s no question that this will get the job done. Plus, it comes with a lifetime warranty.

  6. 6. Best 3-Inch-Diameter Grinder: Kingtop 3-Inch Herb Grinder

    Pros:
    • Magnetic lid unlikely to fall off in bag
    • Can store about an eighth of dried herb
    • Produces a lot of kief in kief chamber
    Cons:
    • Metal threads on lid can wear out over time
    • Users experience problems with threads over time (but they don't mind ordering a replacement unit at this price!)
    • If bud not completely dry, likely to get stuck on teeth (teeth very close together)

    This is probably the best price you can find on a 3-inch grinder (which is slightly wider in diameter than most grinders, which are 2-inches or 2.5-inches across). If you need a little extra room in your storage chamber, this could be great.

    (Still, don’t expect it to hold more than an eighth of ground herb.)

    It’s perfect for travel. Users say they’ve never had the magnetic lid come off in their bag. That’s a pretty huge bonus, if you like to toss your loaded grinder into your purse.

    Like most cheap grinders, the metal threads may loosen over time, making it less likely to stay together. One customer even took steel wool to the threads to make sure any loose metal particles wouldn’t interfere with the threads.

    Others note that your herb must be completely dry — otherwise, be prepared to use a poker to stick some crumbs through the holes.

    Still, if you’re looking for a 3-inch wide grinder at a cheap price point, this is definitely your best option.
