Cobalt Drill Bit, 29/64 In Diameter - Vermont American

The Vermont American 12679 Cobalt Drill Bit is engineered for professional technicians and mechanics routinely tackling challenging materials. With its 29/64-inch diameter and robust cobalt alloy construction, this drill bit ensures predictable performance and consistent hole sizing when drilling through tough alloys like stainless steel, high-strength steel, and other difficult metals, even under demanding operational conditions.

Key Features

• Cobalt Alloy Construction: Features a high cobalt content to enhance heat and abrasion resistance, crucial for maintaining edge life and integrity when drilling through demanding materials such as stainless steel, grade 8 fasteners, and spring steel.
• Precision Ground Point: Designed to minimize bit walking and improve starting accuracy on curved or uneven surfaces common on frames, brackets, and exhaust components, often reducing the need for prior center punching.
• Efficient Flute Geometry: Optimized flute design effectively clears chips, which aids in heat management and extends the bit's operational life during continuous or production drilling tasks.
• Accurate 29/64" Sizing: Maintains tight tolerances for critical applications, making it suitable for installing press-fit bushings, repair inserts, sleeves, or preparing holes for tapping larger threads.
• Professional-Grade Durability: Built for demanding environments, this bit performs reliably in drill presses, magnetic drills, and quality hand drills across professional automotive, fleet, and industrial settings.

Applications

This versatile drill bit is well-suited for a wide range of professional applications, including comprehensive automotive and truck repair, chassis and suspension work, and custom fabrication projects. Common uses involve drilling precise mounting holes in brackets and plates, modifying steering and suspension components, working on hitch and tow hardware, exhaust hangers, and structural steel on service bodies and equipment. It is also an appropriate tool for welding shops, maintenance departments, and manufacturing facilities requiring consistent hole quality in hard metals.
