Small-diameter hone 220

Hand honing apparatus type 220 for diameters from 1.5 to 21 mm A special adapter with a friction-clutch can also be used for manual honing when using the 220 unit, this is to protect small diameter honing tools. For honing tools Ø 1.5 to 20 mm Turns your drilling, turning or milling machine into a precision honing machine Very handy design and very easy handling With these honing apparatus, even untrained persons can achieve the highest precision and surface quality immediately and without special training. With micrometric expansion 1 pitch = 0.001 / 0.002 mm expansion of the honing tool 1 complete revolution = 0.02 / 0.04 mm expansion Maximum 15 revolutions, i.e. 0.3 or 0.6 mm The units have an adjustable stop Repetition accuracy within 0.001 mm Honing tools Are expanded evenly and absolutely parallel on the entire circumference (self-centring) Available from Ø 1.5 mm for through holes Available from Ø 1.5 mm for blind holes A micrometric expansion of the honing tools, which work according to the lapping principle, are guarantees for top performance.
