Ideal for drilling low-alloy steel (R<750N/mm²) to hardened alloy steel (R>950N/mm²) and stainless steels. The increased cobalt content provides greater resistance to drill bit deformation, allowing for drilling through hard steels and stainless steel that require consistent cutting throughout the drilling process. Achieve up to 3 times more drilled holes compared to a standard HSS drill bit. Features an auto-centering split point sharpening for efficient material penetration without the need for pre-drilling.
