kwb HI NOX HSS M2 Metal Drill Bit Ø 4 mm with Special Point Geometry for Efficient Drilling in Stainless Steel Cordless Drills and Power Drills, Longer Battery Life

EFFICIENT DRILLING: The HI-NOX HSS M2 Metal Drill Bit features a short, specially shaped spiral flute that reduces the grabbing effect during drilling in metal sheets, making it ideal for sheet metal applications. "QUICK CUT" GEOMETRY: The steel drill bits with special point geometry and a 130° point angle create small metal chips, providing quick and efficient drilling. They are three times stronger than cobalt-containing drills. EXTREME HEAT RESISTANCE: These HSS drill bits are highly heat-resistant and stable even under heavy loads, retaining their hardness and preventing damage to the material at high temperatures. VERSATILE APPLICATIONS: The metal spiral drill bits exhibit excellent cutting performance, especially in all stainless steel varieties, and are also suitable for various steel types, cast iron, and steel castings. ENHANCED DURABILITY: The shaft and spiral of the cylindrical steel drill bit are differentially hardened to reduce the risk of breakage., Manufacturer: kwb
