2.5″ NOTCHED ALUMINUM GRINDER

The 2.5″ Notched Aluminum Grinder from What You Need is a five-piece herb grinder built for people who grind a lot and actually care about their kief. The notched top and bottom give you real grip even with sticky fingers, and the 2.5 inch (63.5mm) diameter hits that sweet spot between pocketable and “daily driver” size. If you want smoother grinds, easier twists, and a dedicated kief setup without babying your gear, this is the one.

Key benefits

• No more slippery twists — Deep notches on both the lid and base give you solid leverage, even when your hands are resin-covered.
• Catch and save every crystal — Multi-layer design with a kief chamber and scoop means your pollen doesn’t just get lost in the teeth.
• Dialed-in grind consistency — Precision-milled aluminum teeth break herb down evenly so bowls, cones, and vapes all burn more smoothly.
• Built to be dropped — All-aluminum body shrugs off everyday knocks way better than cheap plastic grinders.
• Less mess on the table — Five-piece layout keeps herb contained while you grind, tap, and scoop instead of scattering it everywhere.
• One grinder, full setup — Between the storage, screen, and scoop, you don’t need extra little jars just to manage your kief.

Best for

This grinder is made for people who grind daily and are tired of fighting flimsy teeth and sticky lids. If you like keeping a stash of kief for special bowls or topping off joints, the built-in catcher and scoop are going to see a lot of use. It also makes a solid upgrade if you’re pairing it with a durable piece like our silicone pipes and want a grinder that feels just as tough in the hand.

How to use it

The basics are simple: load your herb into the tooth chamber, close it up, and twist the notched lid against the notched base. The notches aren’t just for looks — they give you way more control so you’re not wrenching on the top when your grinder gets a little sticky.

Ground material drops down into the middle chamber, where you can tap it out into a bowl, paper, or onto a dab mat if you like keeping your surface clean and crumb-free. As you keep using it, fine particles sift through the screen and collect in the bottom kief compartment.

When you’re ready to tap into the good stuff, use the included scoop to pull kief from the bottom section. You can sprinkle it onto a bowl, mix it into a roll, or stash it away in one of our heavy-bottom glass jars if you’re saving up for a special sesh.

For cleaning, just empty out any herb, let sticky parts dry, then brush or wipe off residue. For deeper cleans, a quick soak of the metal sections in isopropyl alcohol, followed by a rinse and full dry, keeps everything turning smoothly.

Fit & usability notes

At 2.5 inches (63.5mm), this grinder feels substantial but still packs easily into a bag or case with the rest of your smoke shop gear. It’s a good size if you’re grinding for yourself plus a friend or two — big enough to handle multiple bowls, but not a bulky puck in your pocket.

The multi-piece stack screws together smoothly when clean. If you’re the type who likes ultra-fluffy grinds, you can give it a few extra twists; if you prefer a little chunk left, back off sooner. The screen and kief catcher will do their thing in the background while you use it however you like.

FAQ

1. Is this grinder good for everyday use?
   Yes — it’s designed as a daily driver. The aluminum body holds up well to regular grinding, pocket carry, and being tossed on the table next to your papers or joint tubes without feeling delicate.
2. Does it have a kief catcher and screen?
   It does. The 2.5″ Notched Aluminum Grinder is a five-piece setup with a main grinding chamber, a middle storage layer, and a bottom kief catcher separated by a fine screen, plus a scoop to collect what builds up down there.
3. Can I use this for small amounts or is it only for big grinds?
   You can do both. The 2.5 inch (63.5mm) size gives you room for bigger loads when you’re grinding for a few heads, but it still works just fine with a single bowl’s worth if you’re keeping things light.
4. How do I clean the grinder?
   Start by emptying all the chambers and brushing out the teeth and screen. For stubborn buildup, remove the metal sections and soak them briefly in isopropyl alcohol, then rinse with water and let everything dry fully before putting it back together.
5. Will the aluminum affect the taste of my herb?
   No, the aluminum is there for strength and precision machining. Once your herb is ground, it’s not sitting in there long — you’re popping it right into your piece, papers, or a storage option like our reusable storage & packaging containers if you’re getting things ready ahead of time.
6. How does this compare to a basic 2-piece grinder?
   A 2-piece is fine if you just want something super simple, but this five-piece gives you way more control and payoff. You get a dedicated kief catcher, a screen to separate fine material, and easier access to your ground herb without it getting packed into the teeth.
7. Is this a good gift for someone who already has a grinder?
   If they’re using a cheap plastic grinder or a tiny metal one with no kief chamber, this is a real upgrade. The notched grip, aluminum body, and multi-piece layout feel a lot more “serious setup,” especially paired with a nice rig or nectar collector in their kit.
