CO2155B
- Cobalt bits with upgraded M42 alloy for long life in hard metal
- Surface hardened with web-helix design and high heat resistance
- Drills stainless steel, cast iron, titanium, other hard metals
Benefits
Cobalt M42 drill bit
provides upgraded M42 cobalt jobber-length bits designed for durability, high heat resistance and hardened surface for stainless steel, cast iron, titanium, light-gauge metal and aluminum
Enhanced M42 alloy material
contains 8% cobalt alloy that delivers 10X life vs. standard bits
Three-flat shank on bits 3/16 In. and larger
deliver better bit grip
High-heat resistant bits
withstand high-temperature applications for extended periods of time
Thick web-helix design
provides additional stability in tough applications
Surface-hardened tip
penetrates tough abrasive materials
Split points on bits 1/8 In. and larger
allow for easy starts with no skating, eliminating the need for a center punch
