Milwaukee Drill HSS-CO 19pc Set

This 19-piece set of high-speed steel drill bits is ground from solid 5% cobalt-alloyed steel to DIN 338 specification, delivering extreme heat resistance for demanding applications. The bits are engineered for drilling high alloy content steels and stainless steel with tensile strengths over 1000 N/mm². Variable flute geometry accelerates material ejection and keeps the bit cooler during use. Each bit features Milwaukee’s QUAD EDGE tip, combining a 135° split point for precise starts without walking and four cutting edges that produce smaller chips to prevent heat build-up and extend working life. The enhanced tapered web strengthens the core for increased flute durability, whilst bits from 5 mm diameter upwards feature a 3-flat shank for superior grip and chuck security.
