- About 1 oz per fill: Enough beans for two large mugs or two espresso doubles.
The faceted aluminum catches light like a cut stone. Underneath the geometry: conical stainless steel burrs, a magnetic walnut handle, a clicking grind dial. Precision disguised as sculpture.

Why you will reach for it every morning
A burr grinder that looks as good on the counter as it grinds in the hand.
- True conical burrs, not blades: Hardened stainless steel cones crush beans to an even particle size. No scorching, no dust-and-boulders. Flatter cups, cleaner extraction.
- Dial in any brew: 12 clicks per rotation at 0.08 mm per click. Tight enough for espresso, open enough for French press, repeatable every time.
- Magnetic crank snaps on and off: Pull the handle free for travel or a drawer, snap it back with one hand. No threads to line up.
- All-metal body that lasts: Machined aluminum with a three-dimensional diamond facet. Won't rust, won't flex, ages well.
- Quiet, grid-free, plug-free: Grind beside a sleeping house or in a cabin off-grid. Just you and the crank.
Specifications
Care & maintenance
Metal forgives mistakes. Burrs demand attention.
- Brush after every grind: A small stiff brush clears retained grounds from the burrs and the catch cup. Oils turn rancid if left inside.
- Deep clean monthly: Take apart the three sections, rinse burrs and chamber under warm water, air-dry fully. The aluminum body wipes clean with a damp cloth.
- Check the center shaft: Every few months, twist the dial through its full range. If you feel grit or resistance, rinse and dry the shaft so it spins freely again.
- Burr longevity: Hardened steel burrs dull slowly and stay sharp through years of daily grinding.
- Wood knob care: Wipe with a barely damp cloth. Once or twice a year, rub a drop of food-grade mineral oil into the wood to prevent cracking.
Frequently asked
How fine is one click on the Diamond Manual Grinder's dial?
About 0.08 mm. The dial has 12 clicks per rotation, tight enough to dial in espresso and open enough for French press, and you can go back to the same click every time.
What is the difference between black and silver?
Both share the same burrs, the same dial, the same aluminum body. Black is matte and modern, silver is brighter and shows the metal grain. Pick the one that fits your counter.
Can it grind fine enough for espresso?
Yes. The conical steel burrs and 0.08 mm click steps let you dial in an espresso grind. Expect roughly 40 to 60 seconds of cranking for a double shot, depending on your pace.
How many beans fit inside?
About 25 to 30 g, enough for two large mugs or a couple of espresso doubles. Grind what you brew and the rest stays fresh in the bag.
Why a magnetic handle?
Magnets let you pull the crank off instantly for storage or travel, with no threads to unscrew. The connection is solid enough to grind and loose enough to pull free with one hand.
Steel burrs vs ceramic burrs: which is better?
Both grind evenly. Hardened stainless steel burrs like these are sharp enough for an espresso grind and dull slowly, staying sharp through years of daily grinding. Ceramic burrs never rust but are more brittle if the grinder is dropped.
Can I travel with it?
Yes. The magnetic crank pulls off, the body splits into three sections, and it needs no plug or battery, so it packs easily into a bag.
Can I rinse the burrs with water?
Yes, for the monthly deep clean. Take the three sections apart, rinse the burrs and chamber in warm water and let everything air-dry fully. After each grind, a dry brush is enough.
What's a good hand grinder for espresso?
You need fine, repeatable steps. The Diamond Manual Grinder has hardened stainless steel conical burrs and a 12-click dial at 0.08 mm per click, tight enough for espresso. The Voyager Hand Grinder has a numbered click dial from espresso to coarse and a conical steel burr. The Precision Manual Grinder also reaches espresso-fine. More: our espresso grinders.
Which coffee grinder has the fewest plastic parts?
Several hand grinders are mostly metal, wood and ceramic. The Diamond Manual Grinder is all-metal machined aluminum with stainless steel burrs and a walnut handle. The Bottega Pine Grinder is pine, cast iron and ceramic burrs with a metal hopper. The Kona Workshop Grinder pairs wood with a cast iron burr. Each page lists its materials; the Precision Manual Grinder, for example, has two small plastic parts (viewing window and dial cap).
I want a coffee grinder that looks like a design object.
The Diamond Manual Grinder has a faceted, machined aluminum body that catches the light, a magnetic walnut handle and stainless steel conical burrs. The Heritage Hand Mill comes in five two-tone wood and metal colorways, such as Black & Walnut or Ivory Crown. The Le Modèle Burr Grinder is a brushed steel electric cylinder.
