COB. DR. 7/16CD - Hanson

The Hanson 63328 COB. DR. 7/16CD is a professional-grade 7/16" cobalt drill bit engineered for demanding drilling applications in automotive and industrial settings. Constructed from M-35 5% cobalt high-speed steel, this drill bit delivers superior hot hardness and abrasion resistance, making it ideal for penetrating challenging materials without compromising bit integrity. Its robust design ensures consistent performance and extended tool life for professional technicians and mechanics.

Key Features

• 135° Split Point: Designed to begin drilling immediately, minimizing bit "walk" and reducing the need for a pilot hole, ensuring precise starts on tough surfaces.
• M-35 5% Cobalt High-Speed Steel: Infused with additional cobalt, this bit offers exceptional resistance to heat and abrasion, allowing for efficient drilling through hardened materials.
• Heavy-Duty Web Construction: Provides enhanced strength and durability, preventing premature breakage and ensuring reliable performance under strenuous conditions.
• 3-Flatted Shank: For improved chuck grip on 7/16" and larger sizes, reducing slippage and enhancing operator control during high-torque applications.
• Laser-Etched Markings: Ensures quick and easy identification of bit size for efficient workflow.

Applications

This Hanson cobalt drill bit is specifically recommended for drilling through a wide range of abrasive and high-tensile strength materials commonly encountered in professional workshops and industrial environments. It excels in applications involving hardened steel, super alloys, titanium, and stainless steel, providing clean, accurate holes with less effort. It is an essential tool for automotive repair, machinery maintenance, and fabrication tasks where standard HSS bits fall short.
