HSS Cobalt Twist Drill Bits

Bosch HSS-Co Cobalt Drill Bits (DIN 338)

Introducing the series of HSS-Co (Cobalt) Drill Bits from Bosch. These high-performance drill bits are manufactured from alloyed high-speed steel to DIN 338 with 5% cobalt content making them resistant to heat and wear, making them ideal for use in tough and hard steels. The HSS-Co drill bits enable up to 40% faster drilling rates and 50% lower feed pressure than standard HSS bits, with a chisel edge and split point drill tip manufactured to DIN338. The bit’s exposed 135-degree self-centring split-point tip combines active cutting and perfect centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm. These drills are ideal for use with pillar drills and drill stands.
