Cobalt Metal Drill Bits – High-Speed Steel, DIN 338 - 4932373346

Cobalt Metal Drill Bits – High-Speed Steel, DIN 338

Engineered for professional use, these metal drill bits are made from solid 5% cobalt-alloyed high-speed steel for extreme heat resistance and durability. Designed to tackle high-strength metals, including stainless steel and alloys with tensile strength over 1000 N/mm², these bits offer precision, longevity, and superior performance.

Key Features & Benefits:

QUAD EDGE™ Tip – combines a 135° split point and four cutting edges for precise starts and smaller chip formation to reduce heat buildup.

Variable flute geometry – improves material ejection, keeps the bit cooler, and extends life

Enhanced tapered web – wider core towards the shank increases core strength and flute durability

3-flat shank (from ⌀ 5 mm) – ensures better grip and prevents chuck slippage

Heat-resistant cobalt steel – ideal for drilling high alloy steels and metals with tensile strength >1000 N/mm²
