Built to M42 cobalt steel grade, it carries a gold oxide coating that improves lubricity and heat resistance during extended cuts. The 135-degree split point reduces walking and requires no center punch on most surfaces. At 6-5\/8 inches overall length with a 4-13\/16-inch flute length, this bit is sized for general-purpose jobber work on the drill press or hand-held power drill. Machinists, fabricators, and maintenance technicians working in metalworking environments are the primary users of this series.\u003c\/p\u003e\n\u003cp\u003eThe 50079 is rated for drilling titanium as its primary workpiece material, making it a practical choice for aerospace, medical fabrication, and precision machining applications where standard HSS bits fail prematurely. The 37\/64-inch diameter with a straight-cylindrical shank fits standard drill chucks without adapters. The spiral flute with regular helix and web-thinned, tapered web configuration promotes chip evacuation and reduces torque in deep-hole applications. This bit meets DIN 338 and NAS 907 Type J standards, which are recognized specifications in aerospace and defense manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for durability in hard metals including titanium\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement on most workpieces\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating improves surface lubricity and extends tool life under heat\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces cutting resistance in deep-hole operations\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for aerospace-grade tooling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill presses and hand-held power drills accepting a 37\/64-inch straight-cylindrical shank.

Secure the workpiece firmly before drilling and confirm the chuck is tightened to the shank before operation. Use appropriate cutting fluid or coolant when drilling titanium or other hard alloys to preserve tool life, as this bit does not support through-coolant delivery.
