Optimum OPTIgrind GH 15T Drill Grinding Machine

The Optimum OPTIgrind GH 15T is a 230 V drill grinding machine for regrinding double-edged twist drills from Ø 3 to 30 mm, with tip angles from 90° to 145°. A CBN grinding wheel and an adjusting aid hold the drill in the right position, so you can restore blunt drills quickly and accurately without prior experience. Workshops save money on new drills and avoid poor cutting caused by badly hand-ground tips. The delivery includes 6 ER 20 and 22 ER 40 collets, enough to cover the whole drill range straight away.
