1/2 In Cobalt Pilot Point Drill Bit - M42 8% Co, Parabolic Flute

Discover the Irwin 1/2 in. Cobalt Pilot Point Drill Bit, built to tackle hard metals with confidence. M42 cobalt steel with 8% cobalt delivers exceptional wear resistance for stainless steel and tough alloys. A 135-degree split-point starts instantly to prevent wandering, while the parabolic flute efficiently cools the cut and clears chips. The no-spin shank ensures a firm grip in standard chucks for steady, accurate drilling.

Benefits in action: This cobalt drill bit delivers clean holes, reduced heat buildup, and longer tool life when drilling stainless steel and hard alloys. Its robust geometry keeps precision intact through tough materials, while the secure shank improves control and minimizes downtime during production.

• M42 cobalt steel alloy with 8% cobalt provides superior wear resistance for metalworking in stainless steel and hard alloys.
• 135 degree pilot point geometry ensures immediate penetration and resists walking on smooth metals.
• Parabolic flute design enhances heat control and faster chip removal for longer bit life and smoother drilling.
• No-spin shank prevents bit slippage in drill chucks, delivering steadier operation and improved accuracy.
• Reduced shank option: 7/16 in and 1/2 in sizes include a 3/8 in shank for compatibility with smaller tool holders.

Experience precision and durability: Built to withstand demanding metalworking environments, this Irwin cobalt drill bit delivers consistent holes, cleaner finishes, and extended service life. The combination of cobalt enrichment, pilot point geometry, and heat-efficient flute design supports productivity in stainless steel and tough alloys. With a secure no-spin shank and versatile length, it suits both stationary presses and handheld drills, reducing chatter and downtime.
