Metal Grinder Thorinder Large — Precision-Milled Herb Grinder
The Metal Grinder Thorinder Large is a four-part aluminium herb grinder built for people who are done replacing cheap grinders every few months. Precision-milled from aerospace-grade aluminium with stainless steel components, the Thorinder features a clear acrylic lid so you can watch your herb break down to exactly the consistency you want. It arrives in a presentation casket with a cleaning tool — the kind of detail that tells you the manufacturer actually cares about the product beyond the sale.
Choose Your Colour
The Thorinder Large comes in four anodized finishes: Blue, Green, Orange, and Silver. All four are identical in build and performance — the anodized coating provides the same scratch resistance regardless of colour. Pick whichever one you won't lose on your coffee table.
| Variant | SKU |
|---|---|
| Blue | HS0190 |
| Green | HS0191 |
| Orange | HS0192 |

Complete your setup: A grinder this good deserves decent storage. Pair the Thorinder Large with a UV-blocking stash jar to keep your freshly ground herb from drying out. If you're grinding for a vaporiser, check out our rolling trays and dosing capsule sets — they make loading sessions far less fiddly.
Why the Thorinder Large Is Worth the Upgrade
We've sold hundreds of grinders over the years, and the pattern is always the same. Someone buys a cheap acrylic grinder, the teeth dull within a month, the threading cross-threads, and they're back in the shop. The Thorinder breaks that cycle. The teeth on this thing are CNC-milled — meaning they're cut by a computer-controlled machine from a single block of metal, not cast in a mould. That matters because milled teeth have sharper edges and more consistent spacing, which translates to an even grind with less effort on your part.
The 62mm diameter gives you a proper grinding surface. If you've been using a 40mm or 50mm grinder, the difference is immediately obvious — you can load more herb, and the teeth have room to work instead of jamming up. The four-part design separates your ground herb from the fine kief that falls through the stainless steel mesh screen. Over a few weeks, that bottom chamber collects enough to make your day noticeably better.
Then there's the clear lid. It sounds like a small thing, but once you've used it, you won't go back to guessing. You pop the lid on, give it a few twists, and you can see exactly when the grind hits the consistency you want — coarser for joints, finer for vaporisers. No more opening and closing to check.
How to Use the Thorinder Large Grinder
- Unscrew the clear lid from the grinding chamber. Break your herb into smaller pieces by hand — roughly thumbnail-sized — and place them between the teeth. Don't overfill; leave room for the teeth to do their work. About 1-2 grams fits comfortably.
- Replace the lid and twist back and forth 8-12 times. Watch through the clear window — you'll see the herb drop through the holes into the collection chamber below once it's ground fine enough.
- Unscrew the grinding chamber from the collection section. Your ground herb sits on the stainless steel mesh screen, ready to use. Scoop it out with the included cleaning tool or tap it onto your paper, bowl, or vaporiser chamber.
- Over time, fine trichome particles (kief) fall through the mesh into the bottom catcher. Unscrew the bottom chamber periodically to collect it. Some people save it for weeks — the longer you wait, the more satisfying the payoff.
- Clean the grinder every few weeks by brushing the screen and teeth with the included cleaning tool. For a deeper clean, disassemble all four parts and soak them in isopropyl alcohol for 20-30 minutes, then rinse with warm water and dry completely before reassembling.
Frequently Asked Questions
What size is the Thorinder Large compared to the Mini?
The Thorinder Large has a 62mm diameter, while the Mini sits at 50mm. The Large handles bigger loads and gives you a more efficient grind per session. Go Large for home use, Mini for travel.
Does the clear lid affect durability?
The acrylic window is set into the aluminium lid, not replacing it structurally. It's recessed and protected by the metal rim, so it won't crack from normal use. We haven't seen one come back broken yet.
How fine does the Thorinder grind?
The CNC-milled teeth produce a medium-fine grind that works well for both rolling and vaporising. Fewer twists give you a coarser result; more twists push it finer. The clear lid lets you dial it in visually.
Is the kief screen easy to clean?
The stainless steel mesh screen does clog over time, especially with sticky herb. Use the included cleaning tool to brush it after each session. A 20-minute soak in isopropyl alcohol every few weeks keeps it flowing freely.
Can I put the Thorinder in the freezer to collect more kief?
Yes, and it actually works. Freezing the grinder for 20-30 minutes makes trichomes brittle and easier to shake through the screen. Give it a firm tap on a hard surface after freezing and check the bottom chamber. The aluminium and stainless steel handle the cold without any issues.
What colours are available?
Blue, Green, Orange, and Silver. All four use the same anodized aluminium finish with identical scratch resistance. The colour is purely aesthetic — pick the one you like.
Does the Thorinder come with a warranty?
The grinder arrives in a presentation casket with a cleaning tool. Warranty terms depend on the manufacturer. That said, the precision-milled construction means we rarely see these come back with defects — the build quality speaks for itself.
