Eagle Cutting Tool SC400-032-I Cobalt Stub Drill 1/2 in

Product Description

The EAGLE CUTTING TOOL SC400-032-I is a cobalt stub drill with a 1/2-inch diameter, designed for drilling through hard and abrasive materials in demanding trade and industrial applications. Cobalt construction gives the bit superior heat resistance compared to standard high-speed steel, making it well-suited for sustained drilling cycles without rapid edge degradation. The stub length profile provides added rigidity, reducing deflection when starting holes or working in confined spaces. Licensed tradespeople including electricians, pipefitters, HVAC technicians, and plumbers rely on stub-length cobalt drills when penetrating structural steel, stainless, and other tough substrates.

This drill is appropriate for use in metal fabrication, mechanical contracting, and field service work where a short, stiff cutting tool is needed to maintain hole accuracy. The 1/2-inch diameter makes it a common selection for conduit knockouts, pipe penetrations, and structural steel drilling where standard jobber-length bits are prone to walking or flexing. The cobalt alloy composition handles interrupted cuts and harder alloys that would quickly dull conventional twist drills.

Key Features

• 1/2-inch cutting diameter for standard trade drilling applications
• Cobalt alloy construction provides elevated heat resistance and extended tool life in hard metals
• Stub length profile increases rigidity and reduces bit deflection during use
• Minimum order quantity of 1, allowing single-unit procurement

Compatibility

Designed as an OEM-style replacement or standard supply item compatible with 1/2-inch drill chucks on corded and cordless drilling equipment used in electrical, plumbing, HVAC, and general mechanical contracting work.

Installation Notes

Cobalt stub drills should be installed by a qualified tradesperson using properly rated drill equipment with a chuck rated for 1/2-inch shank tooling. Always secure the workpiece before drilling and use cutting fluid when working through stainless steel or hardened alloys to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is evident to avoid workpiece damage or injury.
