7/64 In. Cobalt Pilot Point Drill Bit | M42 8% Cobalt, Parabolic Flutes

Discover Irwin 7/64 in. Cobalt Pilot Point Drill Bit, engineered for metalworking demanding stainless steel and tough alloys. Crafted from M42 cobalt steel with 8% cobalt, this bit delivers exceptional wear resistance and extended life. Its 135° split point and pilot point design bite instantly, delivering accurate starts with minimal wandering. The parabolic flute geometry aids heat dissipation, keeping the edge sharp longer.

Boosts Performance & Longevity: In hard metals, the cobalt alloy minimizes heat buildup while resisting dulling, enabling more holes per bit. Built for repeated use, this drill bit helps boost productivity and deliver cleaner holes with less effort.

• Pilot Point & 135° Split Point: Delivers immediate starts and helps prevent wandering on stainless steel and other hard metals, improving hole accuracy.
• 8% Cobalt Alloy (M42): Provides superior hardness and wear resistance for drilling through stainless steel and tough alloys.
• Parabolic Flutes: Supports rapid chip removal and reduces heat buildup, extending the bit's life during demanding metalwork.
• No-Spin Shank: Minimizes bit slippage, ensuring stable operation with drills and drill presses.
• Jobber Length with Shank Options: Standard length for versatile metal drilling; larger sizes like 7/16 in and 1/2 in use a 3/8 in reduced shank for compatibility with common chucks.

Why this cobalt drill bit stands out: It blends high-grade cobalt tooling with smart geometry to deliver precise, durable performance on demanding metals. From quick starts to extended life in stainless steel, this bit is built for professionals who value reliability, efficiency, and clean, accurate holes. Whether you’re fabricating parts or performing maintenance, this drill bit helps you work faster with less effort.
