Metal Grinders

A Metal Grinder is an essential accessory for any rolling setup, helping create an even, fine grind for cleaner filling, more consistent airflow, and a more even burn. Compared with coarsely broken material, a well-ground preparation reduces loose pockets and dense clumps.

Metal construction also offers greater durability than plastic or acrylic alternatives. Sharp teeth, magnetic closures, and precision threading help provide reliable performance over repeated use. This collection includes the Magnetic No.1 Shark Teeth Grinder and options from brands such as Head Chef, Santa Cruz Shredder, and RAW.

Why Choose A Metal Grinder

Teeth That Stay Sharp 

Metal grinder teeth, typically milled from aluminium or zinc alloys, maintain their cutting edge through hundreds of uses. Plastic and acrylic teeth dull relatively quickly, producing a torn rather than cut result that affects the consistency of the grind. A Metal Herb Grinder with well-designed teeth cuts cleanly through material rather than dragging or mashing it, producing a more uniform particle size throughout.

Magnetic Closure for a Secure Grind 

Most quality Metal Grinders use a rare-earth magnet to keep the lid closed during grinding. The magnet creates a firm closure that prevents the lid from spinning off if you lose your grip, keeps the grinder together in a bag or pocket, and means you can apply firm downward pressure during grinding without the lid lifting. The Magnetic Metal Grinder design is now the standard across most metal grinder brands for good reason.

Shark Teeth Design: More Cuts Per Rotation 

The shark-tooth tooth profile used in quality metal grinders features angled, pointed teeth arranged to pull material inward and cut on each rotation rather than simply pushing it around. More teeth contacting the material per rotation means a finer, more even grind for the same amount of effort compared to a fewer-tooth or peg-style grinder.

Durable Enough for Daily Use 

A quality Metal Tobacco Grinder handles daily use without degrading in the way that plastic alternatives do. Aluminium alloy grinder bodies resist cracking, the thread does not strip under normal use, and the magnet does not weaken over time. For daily rollers who grind multiple times per day, the lifespan difference between a metal and a plastic grinder is significant.

Multiple Chamber Options 

Metal Grinders are available in 2-part, 3-part, and 4-part formats, from a simple two-piece grind-and-tip to a full four-chamber sifter with a pollen/kief collection screen at the bottom. The additional chambers collect the fine particles that pass through the mesh screen, which accumulate in the bottom chamber over time and represent the most concentrated material from the grind.

Small Metal Grinder Options for Pocket Carry 

Metal grinders are available from pocket-friendly 40–50mm diameters right up to large and jumbo sizes above 90mm. A Small Metal Grinder at 40mm fits easily into any pocket, handles a single roll-up quantity per grind, and is practical for on-the-go use. Larger grinders suit those who prepare more material at once or prefer fewer, larger grinds per session.

Clean Up Easily, Last for Years 

Metal grinder bodies clean effectively with isopropyl alcohol and a small brush; the metal surface does not absorb residue or stain permanently the way acrylic does. Regular cleaning keeps the threads moving smoothly, prevents tooth clogging, and extends the usable life of the grinder indefinitely.

2-Part vs 3-Part vs 4-Part Metal Grinders

The number of parts is the most important buying decision in the metal grinder category. Each format produces the same ground output but handles the collection and fine material differently.

2-part grinders are the most compact and straightforward. Grind, open, and tip the material out of the teeth chamber. No separate collection below. Best for Pocket Metal Grinders and minimal-carry situations.

3-part grinders add a catch chamber below the grinding teeth that collects the ground material through holes in the base. No need to tip the grinder; the material falls through into the lower chamber ready to use. No screen, no kief collection.

4-part sifter grinders are the most complete format. The catch chamber sits above a fine mesh screen. Material fine enough to pass through the screen falls into the kief collector at the bottom. Over multiple grinds, the kief chamber collects a concentrated fine material that many users save separately.

• Magnetic No.1 Shark Teeth Grinder  The Magnetic No.1 Shark Teeth Grinder uses a sharp shark-tooth cutting profile and a magnetic lid closure for a secure, consistent grind. The shark-teeth design cuts more efficiently than a standard peg-style grinder, producing a finer, more even result per rotation. Magnetic closure keeps the lid firmly in place during grinding and prevents accidental opening in a bag or pocket. A reliable, accessible Metal Herb Grinder for everyday rolling use.
• Mini Pocket Magnetic Plastic Grinder 40mm  The 40mm Mini Pocket Magnetic Plastic Grinder is the compact companion to the Shark Teeth Grinder, a 40mm pocket-sized grinder with the same magnetic closure in a lightweight plastic body. For those who want the convenience of magnetic closure in the smallest possible form factor, the 40mm format handles a single session's quantity and fits in any pocket. Not a metal body, but it shares the magnetic closure feature with the metal range.

• Chongz and Other Brands  Chongz produces a range of metal sifter grinders in aluminium alloy at mid-range price points across multiple sizes and colours.

Metal Grinder Size Guide

The medium size (55–63mm) covers the widest range of everyday use cases and is the most commonly purchased format in the UK metal grinder market.

How To Use a Metal Grinder

1. Remove the lid by unscrewing it or lifting it from the magnetic closure.
2. Break the material into rough pieces and place them between the teeth, avoiding the centre post.
3. Replace the lid and rotate it back and forth several times with light pressure.
4. Open a 2-part grinder to remove the ground material, or unscrew the lower chamber on 3-part and 4-part designs.
5. For sifter grinders, gently tap before opening to help fine material pass through the screen.
6. Use the evenly ground material to fill your rolling paper or cone.
7. Clean regularly by brushing away residue and fully drying the grinder before reassembling.
