ProMaxx Cobalt Drill Bit - Precision Tooling for Hard Metals - ProMaxx Tool by Milton

The ProMaxx Cobalt Drill Bit, model SSSC270, by ProMaxx Tool by Milton, is an indispensable precision tool for professional technicians and mechanics tackling the toughest materials. Engineered for superior performance, this drill bit consistently delivers clean, accurate holes and an extended service life in demanding automotive and industrial environments.

Key Features

• Specialized M42 Cobalt Alloy Construction: Offers exceptional hardness and heat resistance, maintaining sharpness and structural integrity when drilling through tough, abrasive metals up to Rockwell (Rc) 55, including stainless steel and titanium.
• Precision Ground Flutes & Cutting Edges: Designed for optimal chip evacuation, these features minimize material buildup and heat, ensuring cleaner holes and more efficient drilling operations. This thin web design allows for fast, clean drilling and chip clearing.
• 135° Split Point Tip: This self-centering, micro-edge tip initiates drilling on contact, effectively preventing bit "walking" and often eliminating the need for pilot holes, which enhances accuracy and operational speed. It also works well on curved shapes.
• High Strength Design: Built to withstand high torque and stress, its robust construction ensures reliable, sustained performance and retains cutting edge sharpness even under strenuous conditions. The machine-shop-grade tooling is ground straight to ensure accurate and repeatable results.

Applications

This ProMaxx drill bit is an indispensable tool for reliable drilling in extremely hard and abrasive materials across various professional sectors.

• Automotive Repair & Fabrication: Ideal for penetrating chassis components, engine parts, exhaust systems (especially for drilling out broken exhaust studs), and other vehicle applications constructed from tough alloys.
• Industrial Metalworking: Suited for demanding industrial tasks involving stainless steel, high-tensile alloys, and heat-treated steels where precision and tool durability are critical. This includes materials up to and including Rc55.
• Cast Iron & Hardened Materials: Effectively drills through cast iron and other hardened metals, including boron and ultra-strength steel, commonly encountered in machinery maintenance, structural components, and heavy equipment.
