7/16" Cobalt Drill Bit - Vermont American

The Vermont American 12628 7/16" Cobalt Drill Bit is engineered for professional performance in demanding drilling applications. Constructed from a premium cobalt steel alloy, this bit offers superior heat resistance and exceptional durability, making it an indispensable tool for working with hard and abrasive metals. It is designed to withstand the intense friction and heat generated during heavy-duty use, ensuring a longer lifespan and consistent results.

Key Features

• Premium Cobalt Steel Construction: Made from a high-speed steel (HSS) alloy containing 5-8% cobalt, providing enhanced hardness, wear resistance, and extended tool life, particularly in challenging materials.
• Exceptional Heat Resistance: The cobalt blend allows the bit to maintain its cutting edge integrity at high temperatures, preventing premature dulling and ensuring consistent performance during aggressive drilling.
• 135° Split Point Tip: Engineered for precision starting, this self-centering tip reduces bit walking or skating on the workpiece and allows for faster penetration with less pressure, often eliminating the need for a pilot hole.
• Optimized for Hard Metals: Specifically engineered to excel in drilling tough materials that challenge standard drill bits, delivering reliable results in professional environments.
• Resharpenable Design: Built for long-term value, this cobalt drill bit can be resharpened to extend its effective lifespan and maintain peak cutting performance.

Applications

This 7/16" Cobalt Drill Bit is ideal for a wide range of professional tasks, particularly in automotive, industrial, and fabrication settings. It is highly effective for:

• Drilling through stainless steel, hardened steel, and alloy steel components.
• Creating clean, precise holes in cast iron, tool steel, titanium, and other high-strength metals.
• Enlarging existing holes or preparing openings for threading in heavy-duty machinery, automotive chassis, and structural components.
• General metalworking, fabrication, and maintenance applications where durability and heat resistance are critical, including aluminum, brass, and certain plastics.
