Cobalt Drill Bit, 17/64 In Diameter - Vermont American

The Vermont American 12667 Cobalt Drill Bit, with a 17/64 inch (0.2656") diameter, is a jobber-length tool engineered for rigorous drilling tasks in professional automotive and industrial settings. Designed for superior performance and extended tool life, it efficiently cuts through tough materials like stainless steel, hardened alloys, and abrasive cast iron. Its slightly larger diameter compared to a 1/4" bit offers beneficial clearance for oversized fasteners or materials subject to thermal expansion during assembly.

Key Features

• M35 Cobalt Steel Construction: Crafted from M35 cobalt steel, this drill bit provides enhanced heat resistance and edge retention, making it suitable for demanding applications involving stainless steel, high-tensile alloys, and abrasive cast iron.
• 135° Split Point Tip: Features a precision 135-degree split point design that initiates cutting immediately upon contact, effectively eliminating bit walking and reducing the need for a pilot hole.
• Consistent Hole Accuracy: Engineered to consistently produce clean, precise holes, a critical factor for secure fastening and component integration in professional automotive and industrial applications.
• Efficient Chip Ejection: The optimized flute geometry facilitates rapid chip removal, preventing clogging and supporting faster, more consistent drilling performance across diverse materials.
• Extended Durability: The inherent hardness and heat resistance of the cobalt steel construction ensure prolonged operational life, even under continuous heavy-duty use.

Applications

This 17/64 inch cobalt drill bit is a valuable tool for technicians and mechanics across various sectors, proving highly effective for:

• Automotive Repairs: Ideal for creating precise clearance holes for bolts, screws, and threaded inserts in automotive chassis, engine components, and and exhaust systems.
• Industrial Fabrication: Suited for drilling through hard metals in industrial machinery parts, fixtures, and molds, including materials such as hardened steel, titanium, and Inconel.
• Maintenance & MRO: Essential for demanding repair and overhaul operations in fabrication shops, machine shops, and professional garages that regularly encounter difficult or abrasive materials.
