11/64 In Cobalt Drill Bit – M42 Alloy, 8% Cobalt, Pilot Point

Introducing Irwin 11/64 in. Cobalt Drill Bit—a high-performance tool engineered for stainless steel and other hard metals. Constructed from an M42 cobalt steel alloy containing 8% cobalt, this bit delivers outstanding wear resistance and heat tolerance for demanding drilling tasks. The precision ground pilot-point geometry starts holes quickly and resists wandering, while a parabolic flute design ensures efficient chip evacuation and cooler operation. The non-spin shank keeps the bit aligned in the chuck for steadier drilling. With its jobber-length body, it handles a broad range of metalworking applications.

Superior durability and efficiency: When cutting through tough metals, this cobalt bit maintains sharpness longer and reduces the need for re-drilling, helping you finish projects faster with less tool wear. Its optimized geometry minimizes heat buildup, extending bit life in stainless steel and other alloys.

• Cobalt-infused M42 alloy delivers exceptional wear resistance for hard metals, including stainless steel, with improved heat tolerance.
• Pilot-point geometry promotes precise entry and reduces wandering on metal surfaces.
• Parabolic flute design enhances cooling and chip evacuation to prolong cutting life.
• Non-spin shank prevents slippage in the drill chuck during heavy-duty drilling.
• Diameter options include 11/64 in, with 7/16 in and 1/2 in variants offering a 3/8 in reduced shank for compatibility with smaller drills.

Why choose this cobalt drill bit for metalworking: Built for professionals who demand fast, accurate holes in stainless steel and tough alloys, this bit delivers reliable performance, reduced downtime, and long-term value for metal fabrication and maintenance tasks.
