Built to the M42CO series specification, this bit features a 135-degree split point that reduces walking and lowers thrust force at entry. The straight-cylindrical shank fits standard drill chucks without adapters. A web-thinned, tapered web construction improves chip evacuation and extends tool life in demanding production and maintenance applications. At 0.272 inches in diameter (Letter I), it falls within the 0.2500 to 0.3000 inch size range. This bit is intended for use by machinists, maintenance technicians, and trade professionals working with harder workpiece materials.\u003c\/p\u003e\u003cp\u003eThis screw machine length bit is designed for applications where a shorter, stiffer tool is preferred over a jobber-length bit, particularly in tight-clearance setups or when using turret lathes, CNC machining centers, drill presses, or hand-held power tools. The 2.5xD flute-to-diameter ratio and 1.5-inch flute length make it well suited for shallow-to-moderate depth holes in hard material. Its regular spiral and right-hand cut configuration are standard for most metal-drilling operations encountered in HVAC fabrication, mechanical contracting, and general metalworking.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.272 inch (Letter I) diameter cobalt construction rated for high-performance drilling in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces bit walking and decreases feed pressure required at entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web improves chip flow and reduces heat buildup during drilling\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides added rigidity compared to jobber-length bits in confined setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard three-jaw drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; M42 material grade for elevated heat and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for screw machine length cobalt drill bits in the 0.2500 to 0.3000 inch diameter range, Series M42CO, conforming to ANSI standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only when the spindle is fully stopped and power is locked out or the tool is unplugged. Secure the shank fully in the chuck and verify runout before beginning a cut. Use appropriate cutting fluid or coolant for the workpiece material to maintain bit temperature and extend tool life.
