Bosch HSS-G twist drill bit set is a 25-piece set with bit sizes from 1 to 13 mm and all DIN 338. The drill bits are fully ground HSS so they provide up to a 40% faster drilling rate and up to 50% lower feed pressure. The drill bits have cylindrical shanks enabling use in drill drivers and stands. With a 135° tip split point tip, h8 diameter tolerance and drill bit type N you will achieve perfect centring and precise cutting with no wondering due to a split point tip.
