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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high-speed steel construction for durability in heavy-duty drilling\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating extends cutting life and reduces friction\u003c\/li\u003e\n\u003cli\u003e135-degree split point is self-centering on aluminum, bronze, superalloy, and wood\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces axial thrust at the drill tip\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral flute provides consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/2-inch shank fits standard keyed and keyless chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard jobber-length drill bit compatible with any drill press, hand drill, or milling setup accepting a 1\/2-inch straight-cylindrical shank.
