Triumph Twist Drill 011507 Cobalt Drill Bit 7/64 in

Product Description

The TRIUMPH TWIST DRILL 011507 is a cobalt jobber-length drill bit designed for high-performance drilling in tough materials. Built to Series T1C standards, this bit features a 135-degree split point for self-centering starts and reduced walking on hard surfaces. The gold oxide coating provides heat resistance and extended tool life during demanding drilling operations. At 0.1094 inches (7/64 inch) in diameter with a 2-5/8 inch overall length, it suits a wide range of precision hole-making tasks. Right-hand cut with a regular spiral flute, it is suited for trade professionals and machinists working with alloy and alloy steel workpieces.

This drill bit is intended for use in alloy steel and alloy material applications where a standard high-speed steel bit falls short. The 1-1/2 inch flute length and web-thinned, tapered web configuration improve chip evacuation and reduce cutting resistance. It is a practical choice for maintenance technicians, fabricators, pipefitters, and industrial service pros who regularly drill through hardened or work-hardened metals. The straight-cylindrical shank fits standard drill chucks without adapters.

Key Features

Compatibility

Designed for drilling alloy and alloy steel workpieces; the straight-cylindrical shank is compatible with standard keyed and keyless drill chucks accepting a 7/64 inch shank diameter.

Installation Notes

This bit is installed by a machinist, fabricator, or maintenance technician using a standard drill press, hand drill, or magnetic drill. Secure the straight-cylindrical shank firmly in the chuck before operation and verify chuck runout is within acceptable limits. Use appropriate cutting fluid or coolant when drilling alloy steel to manage heat and preserve coating integrity. Follow all applicable shop safety practices and wear proper eye protection during operation.
