Eagle Cutting Tool C1090-037-I Cobalt Drill Bit 37/64 in

Product Description

The EAGLE CUTTING TOOL C1090-037-I is a 37/64-inch cobalt screw machine (stub) drill bit with a 1/2-inch straight shank. Cobalt high-speed steel construction provides elevated heat resistance, making this bit well suited for drilling through hard metals, stainless steel, cast iron, and other tough materials that would wear down standard HSS tooling. The stub-length flute design increases rigidity and reduces deflection during use, which improves hole accuracy in demanding production and maintenance environments. Licensed tradespeople and machinists rely on this type of bit for repetitive drilling where durability and precision matter.

This drill bit is designed for use in machine shop, fabrication, industrial maintenance, and field service applications where a 37/64-inch hole diameter is required. The 1/2-inch shank is compatible with standard drill chucks and keyed chuck setups found on drill presses, lathes, and heavy-duty hand drills. Typical applications include metal fabrication, structural steel work, pipe fitting preparation, and equipment repair where hard or abrasive base materials are encountered.

Key Features

• Cobalt high-speed steel construction for heat resistance and extended tool life in hard metals
• Stub screw machine length increases rigidity and reduces bit deflection
• 37/64-inch cutting diameter for precise hole sizing
• 1/2-inch straight shank fits standard drill chucks and drill press setups
• Suitable for stainless steel, cast iron, hardened alloys, and other tough materials

Compatibility

Designed as an OEM-style replacement or stock tooling option for use with any drill press, milling machine, or heavy-duty hand drill equipped with a 1/2-inch or larger keyed or keyless chuck.

Installation Notes

Installation of this drill bit is performed by machinists, maintenance technicians, pipe fitters, and ironworkers using standard drill chucks. Secure the 1/2-inch shank fully into the chuck before operation and verify chuck key is removed before starting the machine. Use appropriate cutting fluid when drilling hard metals to reduce heat buildup and extend bit life. Always wear appropriate eye and hand protection when operating drilling equipment.
