Hardshell coffee grinder range — conical burr, 64mm flat burr and portable rechargeable grinders in full stainless steel, built to pair with espresso machines

Coffee Grinders — Conical Burr, 64mm Flat Burr & Portable, Built to Pair (OEM/ODM)

A grinder is only as good as its consistency. Ours holds grind size for a year+, kills static so grounds don't fly everywhere, and is built to match your espresso machine line — OEM/ODM from a 20-year factory.

Two Problems Every Grinder Buyer Knows — Solved

The problem

Consumers increasingly demand fresh grinding — but two issues plague the category. First, static: grounds fly everywhere, leaving a mess on the counter instead of in the cup. Second, drift: many grinders' burrs go coarse after six months, so the grind — and the espresso — becomes inconsistent.

The solution

Hardshell engineers both out. Our patented anti-static modules eliminate static so grounds land where they should. And our burrs hold grind consistency for a year+ with minimal drift — because in espresso, consistency is everything.

  • Grind range from fine Espresso to coarse French Press
  • Adjustable grind degree we can tune per market (US slightly coarser, others finer)
  • Full stainless-steel housing · removable burr & bean container for easy cleaning
  • Built to pair with our espresso machines — matching design & finish

Consistency Is Everything — Here's How We Protect It

  • Patented anti-static, two ways. Conical models use upgraded dual negative-ion modules; the 64mm flat-burr CG 2107 uses plasma anti-static. Both neutralize the static that makes grounds fly — so powder lands in your portafilter or cup, not all over the counter. Buyers feel it immediately: no mess, no cleanup.
  • Grind consistency that lasts a year+. Many grinders go coarse after six months. Ours hold their grind size with minimal drift well past a year — so the espresso your customers pull in month 12 tastes like month 1.
  • Tuned per market. We can set the grind degree to your market — slightly coarser for the US (drip heritage), finer for others — and lock that consistency in.
  • Anti-clog grinding path. A common grinder failure is clogging (damp beans, residue). Our grinding path and mess-free chamber are engineered against it.
