Cobalt Straight Shank Drill Bit - 9/64In - Hanson

The Hanson 63109 Cobalt Straight Shank Drill Bit, sized at 9/64 inches, is a professional-grade tool engineered for technicians and mechanics tackling demanding drilling applications. This jobber's length drill bit delivers exceptional performance and durability when working with challenging materials.

Key Features

• 135-Degree Split Point: Designed for instant drilling engagement, this point geometry prevents bit "walking" and ensures precise hole starting without the need for a pilot hole.
• Heavy-Duty Web Construction: The robust web design provides superior strength and durability, minimizing breakage under strenuous conditions, and ensuring faster chip ejection.
• 8% Cobalt Alloy: Constructed of M-42 5 percent (or 8%) cobalt high-speed steel, this drill bit exhibits significantly higher hot hardness and superior abrasion resistance, extending tool life in high-temperature drilling and in tough metals.
• Straight Shank, Jobber's Length: The versatile straight shank allows for use in a wide range of drill chucks, while the jobber's length offers a balance of reach and rigidity for general-purpose drilling tasks.

Applications

This Hanson Cobalt drill bit is specifically recommended for drilling through materials known for their toughness and heat resistance. It is ideal for applications involving hardened steel, super alloys, titanium, and various grades of stainless steel commonly encountered in automotive repair, heavy machinery maintenance, and industrial fabrication. Its robust construction makes it suitable for drilling into exhaust components, specialized fasteners, and structural metals.
