Bosch HSS-G Extra Length Drill Bit 9.5mm Pack of 5

The Long HSS Twist Drill Bit Ground is for drilling deep holes through metal with maximum precision. Its extended length makes this long bit capable of drilling deeply. 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. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges.
