Grinders
by After Grow
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.
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 |
| Silver | HS0193 |
Here are the numbers that matter when you're comparing grinders side by side. The Thorinder Large sits in the 62mm class, which means it handles bigger loads without cramming.

| Primary Material | Aluminium (precision CNC-milled) |
| Secondary Material | Stainless steel |
| Surface Treatment | Anodized (scratch-resistant) |
| Lid | Clear acrylic window |
| Included Accessories | Cleaning tool, presentation casket |

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.
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.
We'd pick the Thorinder over most grinders in the same price range, and here's why: the threading. Pick it up, twist the sections apart, and you can feel how smoothly they separate. There's zero wobble, zero grit. The anodized surface has a satisfying matte weight to it — it feels like a tool, not a toy. The casket it comes in is a nice touch for gifting, though most people toss it after a week.
The honest limitation? The 62mm size means this isn't a pocket grinder. It's a desk grinder, a session grinder, a "lives next to the rolling tray" grinder. If you need something for on the go, look at the Thorinder Mini instead — same build quality, 50mm diameter, fits in a jacket pocket. But for home use, the Large is the one we'd actually grab off the shelf.
Compared to a standard no-name metal grinder, the difference is the longevity. We've seen Thorinders come back into the shop after two years of daily use still grinding like new. The teeth don't round off because the aluminium alloy is harder than what you'll find in budget grinders. The anodized coating means the surface doesn't pick up scratches from keys, lighters, or whatever else lives in your drawer.
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.
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.
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.
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.
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.
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.
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.
