Manufactured to BS328/DIN338RN. Black Finish (W-Finish) This is the most common surface finish and is the result of a steam tempering operation in which steam is passed over the product during a controlled tempering cycle, producing a black oxide layer. Black tools are generally recommended for ferrous applications where the oxide layer aids chip flow, helps to dissipate heat by retaining some coolant on the tool surface and also helps to prevent the tool from staining.

Maximum Precision - The HSS Twist Drill Bit Ground is for drilling through metal with maximum precision. The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect more→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. This bit is designed for drilling holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics.…
