With the 19-piece Hikoki 780698 metal drill bit set, you can bore cleanly and efficiently into tough materials such as stainless steel, alloyed steel, and cast iron. Thanks to the heat-resistant hss-co cobalt alloy, these drill bits stay sharp and resist wear during high-friction operations. The split-point tip design prevents wandering on contact, allowing you to start drilling accurately without pre-drilling or center punching. Built to the din 338 standard, they feature a straight cylindrical shank compatible with standard handheld and pillar drills. Kept in a durable cassette, bits from 1 mm to 10 mm are always organized and ready for work.
