Advantages
Maximum precision - The HSS spiral drill ground ensures maximum precision when drilling in metal.
The self-centring 135-degree split point combines active cutting action with perfect centring without running, delivering maximum precision.
The split tip makes pre-punching or pre-drilling up to 10 mm unnecessary.
This precision ground HSS (High-Speed Steel) drill bit offers up to 40% higher drilling speed and up to 50% lower feed pressure than standard ground HSS drills with chisel edges.
This drill bit is designed for drilling holes in alloyed and unalloyed steel, cast steel, cast iron, sintered iron, temper cast iron, non-ferrous metals and hard plastics.
