RED COBALT - HSS-Ground - DIN 338 Cobalt Metal Drill Bits - 3.0 mm

Milwaukee RED COBALT – HSS-Ground DIN 338 Cobalt Metal Drill Bits

Engineered for extreme durability and precision, the Milwaukee RED COBALT Drill Bits are manufactured from solid, heat-resistant 5% cobalt-alloyed high-speed steel (HSS-Co) in compliance with DIN 338 standards. Designed for demanding applications, they are ideal for drilling high-alloy steels and tough metals with tensile strengths above 1000 N/mm², including stainless steel.

Key Features & Benefits:

5% cobalt-alloyed HSS-Co – withstands extreme heat & ensures superior durability

QUAD EDGE™ Tip – 135° split point for fast, precise starts with no walking

Four cutting edges – smaller chips reduce heat build-up for longer tool life

Variable flute geometry – faster chip ejection & cooler operation

Enhanced tapered web – reinforced core for greater strength & durability

3-flat shank (from Ø 5 mm) – prevents chuck slippage, ensures secure grip

Bronze finish – easy identification & premium appearance

Applications:

Stainless steel

High-alloy steels

Hard metals with tensile strength > 1000 N/mm²
