Coban 98 Flat
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Grinders — where the cup is decided
Shops upgrade machines and discover the grinder was the ceiling. The Coban raises it — shop-speed throughput, tight particle spreads, and burr life measured in tonnes, tracked by the counter.
Burrs are the whole argument. Ours are cut from hardened tool steel or coated in titanium nitride, measured on an optical comparator, and matched in pairs; carriers are machined, not cast, so alignment survives shipping, seasons and years of shots. Chirp-free at zero, even after the ten-thousandth kilogram.
Design & Craft
- Quiet under load — low 70s dB(A) at full song
- 83–98 mm flat tool-steel burrs for shop-speed espresso with tight spreads
- Machined burr carriers hold alignment through shipping and seasons
- Low-retention throat purges with a single dose after adjustment
- Grind-by-weight dosing lands within a tenth of a gram
- Burr wear tracked by kilograms; replacements change in minutes

Questions, Answered
Does it come aligned?
Every unit is shimmed and chirp-checked before dispatch, then re-checked after transport at commissioning. Alignment is a deliverable, not a lottery.
How long do burrs last?
Tool-steel burrs are rated in the specification (typically 800–1500 kg for shop sets); titanium-nitride coatings extend that two- to three-fold. Replacements are stocked for fifteen years and change in minutes.
