Metal drill bits HSS-Ground DIN 338 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 crafted for precision and durability in demanding metal‑drilling applications. Made from cobalt‑alloyed high‑speed steel (approx. 5% cobalt) and ground to the DIN 338 standard, these bits are designed for high resistance to heat, wear and tough materials such as stainless steel and high‑alloy steels with tensile strengths above 1 000 N/mm².  The QUAD EDGE™ tip with a 135° split point ensures fast accurate starts without walking, and the variable flute geometry enhances chip removal and cooling.  The set covers diameters from 1.0 mm through to 10.0 mm, all housed in a practical plastic cassette for organised storage and transport.
