Built from M42 cobalt high-speed steel, it carries a 135-degree split point with web thinning for fast penetration and reduced thrust. The bit measures 2-11\/16 inches overall length with a 1-1\/2 inch parabolic flute length, and features a straight-cylindrical shank with a diameter of 0.2810 inches. The parabolic flute geometry promotes efficient chip evacuation, making it well suited for interrupted cuts and deep-hole applications. It conforms to ASME B94.11M standards and carries an ANSI specification designation.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in screw machine operations and general production drilling. Primary workpiece materials include alloy steel and aluminum. The screw machine length profile fits standard drill chucks and quick-change toolholding systems used in CNC lathes, turret lathes, drill presses, and machining centers. The short, rigid body reduces deflection and improves hole location accuracy compared to jobber-length alternatives. It is a single-bit unit typically purchased by machinists, tool-and-die shops, and maintenance technicians requiring consistent hole quality in metalworking applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat and wear resistance in alloy and aluminum drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for self-centering and reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry for efficient chip evacuation in deep or interrupted cuts\u003c\/li\u003e\n\u003cli\u003eScrew machine length body for added rigidity and improved hole location accuracy\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and quick-change holders\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and ANSI specification requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for screw machine and production drilling applications requiring a Letter K, 0.2810-inch diameter bit in the CLEVELAND Series 2175A line.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and tooling technicians. Secure the shank fully in the drill chuck or collet before operation and verify runout is within acceptable limits.
