Metal drill bits HSS-G Cobalt Set - 19 pc

The Milwaukee Metal Drill HSS-Co DIN 338 19-Piece Set (SKU 4932352470) is a professional-grade drill bit set engineered for precision and durability in demanding metal-drilling applications. Made from cobalt-alloyed high-speed steel (~5% cobalt) and ground to the DIN 338 standard, these bits resist heat and wear in tough materials including stainless steel and high-alloy steels with tensile strengths above 1,000 N/mm². The QUAD EDGE™ tip with 135° split point delivers fast, accurate starts without walking, and the variable flute geometry improves chip removal and cooling. The set covers diameters from 1.0 mm through 10.0 mm in a plastic cassette for organized storage and transport.
