Grinders
by After Grow
The Solinder metal grinder is a 4-part CNC aluminium grinder by After Grow that grinds tough, sticky herb with almost zero effort thanks to 25 diamond-cut teeth arranged in a patented waveform pattern. At 155 grams and 62mm across, it sits heavy in your hand — the kind of weight that tells you straight away this isn't another disposable grinder that'll strip its teeth after six months. We've had these on the shelf for years and they're still the metal grinder Solinder we'd grab if someone asked us to pick one and only one. If you want to buy a grinder that genuinely lasts, this is where your search ends.
The metal grinder Solinder comes in five anodised finishes — Blue, Orange, Red, Grey, and Green. All identical in build and performance; the only difference is the colour of the aluminium. Grey is the understated classic. Orange and Red stand out in a crowd. Blue and Green split the difference. Every unit ships in the original Solinder branded case with a pollen scraper included, regardless of colour.

|---|---|
| Blue | HS0925 |
| Orange | HS0926 |
| Red | HS0761 |
| Grey | HS0155 |
| Green | HS0760 |

Complete your setup: pair the metal grinder Solinder with a set of rolling papers such as RAW Classic or a quality glass pipe like the Fumo Pipe. If you're grinding herb for a dry herb vaporiser, the Solinder's fine, consistent output is exactly what you want feeding into something like the Storm Vaporizer or the Mighty by Storz and Bickel — check our vaporiser range by name to find the right match. You can also order a stash jar or smell-proof pouch to keep everything together.
The Solinder outperforms standard 4-part grinders because every component is CNC machined to precise tolerances rather than stamped or cast. We've sold dozens of grinder models over the years. Plastic ones crack. Cheap metal ones cross-thread within weeks. The teeth dull, the screen clogs, and the lid that "sealed magnetically" starts spinning free after a few months of daily use. We get the returns. We hear the complaints. And that's exactly why we keep coming back to the metal grinder Solinder.
The difference is in the machining. CNC aluminium means every thread, every tooth, and every chamber wall is cut to precise tolerances — not stamped out of a sheet and bent into shape. You can feel it the first time you twist the lid: the magnetic closure snaps firm without wobble, and the grinding action is smooth with just enough resistance to tell you the 25 diamond-cut teeth are actually biting through your material rather than just mashing it. That waveform tooth pattern isn't marketing fluff — the staggered arrangement pulls herb into the cutting edges from multiple angles, so you don't get that annoying spinning-without-grinding that happens with symmetrical tooth layouts. According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), consistent preparation of herbal material is a factor in harm reduction when vaporising rather than combusting — and a quality grinder like the Solinder supports that consistency.
The honest limitation? At 62mm diameter, the Solinder is a medium-sized grinder. If you regularly grind large batches for a group session, you'll be loading it twice. For personal use or sessions with a mate, it's spot on. And at 155 grams, it's noticeably heavier than budget grinders — which is a good thing for your desk drawer but means it won't disappear into a slim jacket pocket. The branded case is useful for transport, though.
The metal grinder Solinder weighs 155 grams, and that heft is the first thing every customer comments on when they pick one up at our counter. The anodised finish has a slightly matte texture — not slippery, not rough, just grippy enough that you can twist it one-handed without it skating out of your fingers. The magnetic lid clicks shut with a satisfying snap. Open it back up and there's zero play in the hinge point — the threads are machined tight enough that the chambers separate cleanly without that gritty, cross-threaded feeling you get with lesser grinders.
The pollen sieve is fine-mesh and sits between the grinding chamber and the bottom collection tank. After a week or two of regular use, you'll find a decent dusting of trichome powder in that bottom chamber. The included scraper is a small flat tool that fits the curve of the tank — use it to gather everything into one corner and press it together. That's your spatula hash, and it's genuinely one of the best perks of owning a 4-part grinder. Compared to a 2-part grinder where everything just falls into the same space, the Solinder actually separates and collects for you. If you want to order the Solinder, we stock all five colours and ship from our Amsterdam warehouse.
Using the Solinder takes under a minute: load, twist, and collect from three separate chambers. Here's the full step-by-step process.
The Solinder metal grinder costs more than generic alternatives but delivers CNC-machined threads, a patented 25-tooth waveform pattern, and a verifiable serial code that budget grinders cannot match. If you're weighing it against a basic no-brand aluminium grinder, here's what the difference actually gets you.
| Feature | Solinder by After Grow | Generic 4-Part Metal Grinder |
|---|---|---|
| Material | CNC machined aluminium | Cast or stamped aluminium |
| Teeth | 25 diamond-cut, patented waveform | Typically 30-50 standard pegs |
| Grind Consistency | Even, medium-fine | Varies — often uneven |
| Thread Quality | Precision-machined, smooth | Can cross-thread after months of use |
| Magnetic Lid | Strong neodymium-style magnet | Weak magnet or friction fit |
| Pollen Sieve | Fine mesh, separate collection tank | Usually included, mesh quality varies |
| Authenticity | Unique serial code, verifiable | None |
| Included Extras | Branded case + pollen scraper | Sometimes a scraper, rarely a case |
| Weight | 155g | 80-120g typically |
The generic grinder works fine for occasional use. But if you're grinding daily, the metal grinder Solinder's thread quality and tooth design make a noticeable difference in how long the grinder stays smooth and how consistent your output remains. We'd pick the Solinder over a budget option every time — the threads alone are worth the upgrade. Buy the Solinder once and you won't need to replace it.
A grinder breaks herb into smaller, even pieces for smoother rolling, packing, or vaporising. A 4-part grinder like the metal grinder Solinder adds a pollen sieve and collection chamber below the grinding teeth, so fine trichome particles are separated and stored automatically. You get a better grind and a bonus stash of potent material over time.
Yes. The Solinder produces a medium-fine grind that works well with most dry herb vaporisers. Conduction vapes generally prefer a finer grind, and the Solinder delivers that with a few extra twists. For convection vapes, a slightly coarser output works — just do fewer rotations.
Every original Solinder has a unique serial code engraved on the body. Visit the After Grow manufacturer's website and enter the code to confirm you've got a genuine product. If you bought it from us, it's authentic — we source directly.
For daily users, a quick brush of the teeth and sieve every week keeps things running smoothly. A full isopropyl alcohol soak every month or two removes built-up resin. Dry all parts completely before reassembling — aluminium doesn't rust, but trapped moisture can cause residue buildup.
The magnetic lid creates a firm seal that contains most odour. The included branded case adds another layer of containment. It won't be completely scent-proof after heavy use — residue builds up in the teeth — but a clean Solinder in its case is about as discreet as a metal grinder gets.
Standard grinders use evenly spaced pegs or diamond shapes in a symmetrical grid. The Solinder's patented waveform staggers the 25 teeth so herb is pulled into the cutting edges from multiple angles simultaneously. The result is less resistance when twisting and a more consistent particle size — you don't get half-ground chunks stuck between the teeth.
For personal use, 62mm is the sweet spot — large enough to grind a solid session's worth in one load, small enough to fit in a bag or drawer. If you're regularly grinding for three or more people at once, you might want something in the 75-80mm range. For one or two people, 62mm handles it comfortably.
The sieve is built into the Solinder's chamber design and isn't sold separately by After Grow. With proper care — gentle brushing, occasional alcohol soaks — the mesh lasts the lifetime of the grinder. Avoid pushing hard objects through the screen, and it'll stay intact.
You can buy the metal grinder Solinder directly from Azarius. We stock all five colours and ship from Amsterdam. Every unit we sell is sourced directly from After Grow, so authenticity is guaranteed with a verifiable serial code.
