Hario Coffee Mill OCTO – octagonal hand grinder with ceramic burrs
The octagonal shape nestles into your palm, giving you a secure grip as you turn it, while the ceramic burrs deliver an even grind – calm, fresh, by hand.
The OCTO brings the octagonal design to your counter and into your backpack. We carry Hario at Coffee Coaching Club.
Shape and burrs
The octagonal body gives you a firm grip while grinding and stands steady on any surface. The ceramic burrs grind evenly, stay sharp for a long time, and never heat the grounds. The grind setting is steplessly adjustable – giving you a wide, finely tunable range from filter to French press.

Who it's for
For anyone who wants a compact hand grinder with a good grip and stepless adjustment – at home and on the go. If you want to grind espresso-fine with real consistency, take a look at the Comandante or electric coffee grinders.
What goes with it
A V60 NEO 02 or an AeroPress, filter papers from our Hario collection and a scale from the Normcore lineup. Beans like the round Nutty Delight or the fruity Wild Peach.
Frequently asked questions
How do you adjust the grind setting?
Steplessly, right at the burrs – that gives you fine-tuned control from filter to French press.
What material are the burrs made of?
Ceramic. Ceramic burrs stay sharp for a long time and never heat the grounds.
Is the OCTO suited for espresso?
It's made mainly for filter, French press, and pour-over. Espresso-fine, highly consistent grinding works more reliably with steel conical or electric grinders.
Roastery tip
The stepless adjustment invites you to explore – one or two clicks coarser or finer noticeably changes the cup. Rich and round with Nutty Delight, bright with Wild Peach. That's our recommendation, one of many.
