Why it exists

Cold mornings at camp, we still want a clean, even grind—not a crushed mess from a cheap mill. Pre-ground coffee goes stale in the bag. This CNC stainless hand grinder is how we keep whole beans whole until the kettle is hot. Dual bearings hold the shaft true so each turn stays smooth. A steel-ball damper lets you click coarseness point to point instead of guessing on a loose collar.

Built for the trail

  • Five-axis CNC stainless burrs hardened to HRC58 for a sharp, consistent cut on espresso, pour-over, and French press.
  • Walnut wood body with food-grade aluminum alloy and stainless hardware; diamond-texture grip that stays put with wet hands.
  • Glass grounds bin holds about 20g—enough for a solo mug or a shared pour without packing extra parts.
  • Click adjustment: set the origin fully clockwise, then count clicks (12 per full turn). Espresso ~10–14; hand brew ~18–24; French press ~25–27.
  • Washable build so you can rinse after a dusty trail day and pack it dry.

No special issues, Everything went smoothly. Description was accurate. Excellent quality

★★★★★ Verified buyerCA15 Dec 2025G2-Black

This is a high quality, all metal grinder. The stainless steel burr is easy to adjust, and makes consistent grind sizes. The wooden knob on the handle is large and comfortable to hold. For espresso, I turn the dial counter clockwise until it stops completely (it stops at 4, not 2), then turn counter clockwise 16-18 clicks. It takes very little effort to grind 8g of beans (enough to fill the basket in my Wacacao Minipresso GR2). I do not recommend using settings 4-6, it grinds it into a fine powder and takes forever - too fine for espresso. Note: you can turn the dial counterclockwise pass 24 at least 3 times! If you keep turning, you can remove the blade. Be careful, don't lose the spring. Overall, highly recommend this reasonably priced (<$25), stainless steel burr grinder.

Excellent grinder. When disassembling, be careful to place the grooved part of the washer in contact with the bearing. It is made of high-quality steel. It weighs about 470 g. The grinder is made of steel and is very sharp, it has 24 positions and can make 3 turns, so you have a total of 72 adjustments, but adjustments from 0 to 6 are not recommended.

Incredible! Excellent grinder for the price. Previously, I had a mini slim+ from the famous Japanese brand that costs more than twice as much, and overall, this Havmore is much better, solid metal body, even and easy grinding, you don't need to apply much force, even a child could grind easily. Perhaps the only detail is that sometimes I want to grind about 25 grams and need to add two or three grams after grinding the first 22, but even so, they fit well in the bottom container. For everything else, I LOVE IT. My coffee tastes much better now.

It's very well made and sturdy. it grinds well and the grind is adjustable. A batch makes a 500 millilitre amount for a french press.

★★★★★ Verified buyerIL03 Oct 2025G2-BlackTranslated

Excellent. Very high quality. Well constructed. Easy to adjust the grinding level and the grinder produces almost no powder.

A grinder with a compact size and weight, but a surprisingly good construction, absolutely suitable for espresso. It has a beautiful, unique design and is easy to use (it doesn't require much effort to turn it).

★★★★★ a***aPL09 Jan 2026G2-greyTranslated

I was pleasantly surprised by the quality of the craftsmanship, I poured in 20 grams of Lavazza, set the grind size to "12", and prepared a cortado using a geyser. I'm not an expert or a professional, I just love coffee. Until now, I used an electric coffee grinder. This grinder has completely changed my attitude towards the process of preparing the product. Quality beans, the right grinder, and we get delicious coffee with different flavors and preferences. Thank you to the seller for the quick processing of the order and the high-quality packaging!!!

★★★★★ a***rGB04 Apr 2026G2-Black

Great grinder for espresso. 24 clicks available and starts at zero. Set to 10 for my Breville Sage Bambino and seems about spot on.

★★★★★ P***oES19 Oct 2025G2-BlackTranslated

Perfect, both in terms of material quality and grind quality. It grinds finely and uniformly enough to make an espresso. I've had others that didn't grind evenly but this one is perfect for its price, plus it's also very stable when grinding.

★★★★★ K***YFR19 Jun 2026G2-BlackTranslated

Excellent grinder that exudes quality. I can fit a maximum of 23.5g of coffee in it. It grinds very evenly and quickly. A tip to grind even faster: use both hands to make circular movements, not just the hand holding the handle.
