Product Description
The Bohrcraft DIN 352 HSS-G short machine tap M 12 x 1,75 Form B is a versatile single-pass tap engineered for both manual operations (tap wrenches, cordless drills) and machine use in drill presses. The Form B spiral point lead chamfer (4–5 threads) pushes chips forward ahead of the tool through the bore, preventing flute clogging and delivering superior surface finish in through holes up to 3xD depth. Manufactured from fully-ground HSS-G steel for steels up to 800 N/mm² (tolerance ISO2 / 6H). Supplied in a plastic split-pack.
