Cobalt M42 Drill Bit

Durable and High-Heat Resistant

Our Cobalt M42 drill bit is designed for durability and high-heat resistance, making it perfect for demanding industrial applications. Unlike standard drill bits, the enhanced M42 alloy material, containing 8% Cobalt, ensures a life 10 times longer than standard bits.

Multi-Purpose Design for Tough Materials

The thick web-helix design provides additional stability, ensuring precision and control even in tough applications. The surface-hardened tip is ideal for penetrating abrasive materials like stainless steel, cast iron, titanium, light-gauge metal, and aluminum.

Variety of Sizes for Precise Drilling

The Cobalt M42 drill bit set includes a range of sizes: 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 3/16", 7/32", 1/4", 5/16", 3/8", and 1/2". This variety ensures you have the right bit for any drilling task, from small to large jobs.

Enhanced M42 Alloy Material

The 8% Cobalt alloy in the M42 drill bit greatly extends its lifespan, making it a cost-effective solution for prolonged use in high-temperature applications. This extended durability ensures consistent performance and reduced downtime.

Perfect for High-Heat Applications

Designed to withstand high-temperature applications for extended periods, the Cobalt M42 drill bit is ideal for forging, heat-treating, and other industrial processes where heat resistance is critical.
