HSS-Co Cobalt Twist Drill Bit, 4.2 mm, for Stainless Steel
A cobalt HSS twist drill for stainless steel and other work-hardening alloys. The cobalt content keeps the edge hard when the cut heats up, which is where a standard HSS drill dulls and starts to rub instead of cut.
Key features
- HSS-Co (5 % cobalt) for stainless and high-alloy steel
- 135° split point, no pre-drilling on many sizes
- Ground flutes clear chips cleanly
- Straight shank for standard chucks
