Metal Grinder 75mm by Tsunami Glass
The Metal Grinder 75mm from Tsunami Glass is a four-piece aluminium herb grinder built for people who grind regularly and in larger batches. At 75mm across, it holds roughly twice the herb of a standard 50mm grinder, which means fewer reloads and a more consistent grind across the board. The strategically angled teeth inside shred rather than crush, giving you an even texture that burns or vaporises uniformly — no hot spots, no wasted material.
Pick Your Colour
This 75mm metal grinder comes in 7 finishes: Gun Metal, Green, Red, Purple, Silver, Black, and Blue. All identical in build and function — purely a style choice. The Gun Metal and Black variants show fingerprints the least, if that matters to you. The anodised coating on all colours resists scratching well, though we'd avoid tossing it loose in a bag with keys and coins.
Why a 75mm Herb Grinder Changes Your Setup
A 75mm grinder processes roughly twice the herb per load compared to a 50mm model, cutting reloads in half during longer sessions. If you've been grinding with a 40mm or 50mm grinder, you know the routine: load, grind, empty, repeat. With a 75mm chamber, you can process enough herb for an entire session — or even a full evening — in a single load. That's not just convenience; it's consistency. One grind means one uniform particle size across everything you pack or roll.
The four-piece design separates your workflow into three tiers. The top chamber grinds. The middle chamber catches your ground herb through precision-drilled holes. And the bottom chamber — the pollen catcher — sits below a fine mesh screen, collecting the trichome-rich dust that falls through over time. After a few weeks of regular use, you'll have a decent stash of concentrated pollen sitting there. Nothing goes to waste.
The Tsunami Glass grinder uses diamond-shaped teeth positioned to interlock without metal-on-metal contact during rotation. That means the cutting edges stay sharp longer and the grind action stays smooth. You'll notice it the first time you twist the lid — there's a satisfying, low-resistance rotation that cheaper grinders simply don't have.

Complete your setup: pair this 75mm grinder with a rolling tray to keep your surface clean and a stash jar to store your freshly ground herb. If you vaporise, a fine grind from a grinder this size feeds perfectly into most dry herb vaporisers — check out the Azarius vaporiser collection for a match. You can also buy a brush set to keep the mesh screen clear between deep cleans.
Why You Actually Need a Proper Grinder
A proper grinder produces a uniform particle size in seconds, which directly improves how evenly your herb burns or vaporises. Tearing herb by hand is the number one way to waste it. You end up with uneven chunks — some too fine, some too coarse — which means uneven burning, hot spots, and half your material going up as harsh, under-extracted smoke. According to the EMCDDA's 2020 report on cannabis preparation methods, mechanical grinding is associated with more controlled dosing compared to hand-preparation, since consistent particle size allows for more predictable results. A quality grinder addresses that in about 5 seconds of wrist action.
The 75mm size specifically suits people who grind for groups, who pre-grind for the week, or who simply got tired of the cramped loading on smaller grinders. It's also the best size for anyone with larger hands or reduced dexterity — the wider body gives you a much better grip. The magnetic lid keeps everything sealed during grinding, so you're not losing herb off the sides when you twist.
One honest limitation: 75mm is not pocket-friendly. This grinder lives on your table, in your bag, or in a drawer. If you need something you can slip into a jeans pocket, look at a 40mm or 50mm grinder instead. But for home use and bag carry, the 75mm is the sweet spot between capacity and portability — and we'd pick it over a 63mm every time for the extra chamber space alone.
How to Use the Metal Grinder 75mm
Using this grinder takes under a minute from loading to collecting your ground herb. Follow these steps for the best results.
- Remove the magnetic lid (top piece) from the grinder body.
- Break your herb into rough pieces — about the size of a pea — and place them between the teeth. Don't overpack; leave a little room so the teeth can do their job. Fill to about 80% capacity for the best results.
- Replace the lid. The magnet will snap it into place.
- Hold the bottom of the grinder in one hand and twist the lid back and forth with the other. 7 to 10 rotations is usually enough for a medium grind. Fewer for coarse, more for fine.
- Unscrew the grinding chamber from the herb collection chamber below it. Your ground herb is sitting right there, ready to use.
- To access your pollen, unscrew the very bottom piece. Over time, fine trichome dust collects here through the mesh screen. Use the small scraper tool (or a guitar pick, honestly) to gather it.
- After each session, give the threads a quick brush to prevent residue build-up. A stiff-bristled brush or old toothbrush works well. For a deeper clean every few weeks, disassemble all 4 pieces and soak them in isopropyl alcohol for 20 minutes, then rinse and dry thoroughly.
