Triumph Twist Drill 012832 1/2 Inch Hss Tin Drill Bit

Product Description

The TRIUMPH TWIST DRILL 012832 is a jobber-length drill bit designed for high-performance metal, alloy, and wood drilling in professional trade applications. Built from M7 high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced heat buildup during continuous use. The 135-degree split point is self-centering, eliminating the need for a center punch on most materials. The straight-cylindrical shank measures 1/2 inch in diameter, and the overall length is 6 inches with a 4.5-inch flute length. This bit is part of the T1HDG heavy-duty series and is rated for high-performance drilling environments.

This bit is suited for drilling aluminum, aluminum alloy, bronze, superalloy, and wood. The right-hand spiral flute with a regular spiral type clears chips efficiently during through-hole and blind-hole operations. The web-thinned, tapered web configuration reduces thrust requirements at the cutting tip, making it well-suited for production drilling, maintenance work, and field service by machinists, millwrights, pipefitters, and general mechanical contractors. It accepts standard 1/2-inch drill chucks and is packaged as a single unit.
