5/32 In Cobalt Pilot Point Drill Bit – M42 Steel, 8% Cobalt, No-spin Shank

Presenting the Irwin 5/32 in cobalt pilot point drill bit. Built from M42 high-speed steel with 8% cobalt, this bit delivers exceptional wear resistance for stainless steel, abrasive metals, and other hard alloys. The 135° pilot point begins cutting on contact to prevent wandering, while a parabolic flute design promotes efficient chip removal and cooler operation. The no-spin shank keeps the bit firmly seated in the chuck, and the jobber-length body provides versatile reach; the 7/16" and 1/2" sizes feature a 3/8" reduced shank for compatibility with standard tool systems.

Benefits Paragraph: This drill bit enables cleaner holes with less effort when drilling tough metals, including stainless steel and hard alloys. The cobalt alloying preserves sharpness longer than standard high-speed steel, while the designed tip reduces walking for accurate starts and fewer rework incidents.

• 8% cobalt alloy steel provides outstanding wear resistance for tough metal drilling tasks, including stainless steel.
• 135° pilot point geometry creates immediate contact, minimizes walking, and improves first-hole accuracy for stainless steel and hard metals.
• Parabolic flute configuration fosters rapid heat dissipation and extended drill life during heavy-duty drilling.
• No-spin shank design prevents bit slippage in the chuck for reliable performance in demanding applications.
• 7/16" and 1/2" sizes come with a 3/8" reduced shank for compatibility with common power drills and accessories.

Why This Product Stands Out: Designed for professionals who demand durability and precision, this cobalt bit delivers consistent results across hard metals and stainless steel. Its robust construction reduces wear, extends service life, and supports faster project completion. Trust it for clean holes, reduced chatter, and reliable performance in fabrication, automotive, and maintenance tasks.
