Built to the M41 cobalt high-speed steel specification, it delivers the heat and wear resistance needed when cutting hardened steel, stainless steel, cast iron, and similar tough workpiece materials. The bit measures 0.147 inches in diameter (Wire Size 26) with an overall length of 2.0625 inches and a flute length of 1 inch. The 135-degree split point reduces walking and lowers the thrust required to start a hole without a center punch. A tapered web with web thinning supports chip evacuation and extends cutting life in repetitive-cycle applications.\u003c\/p\u003e\u003cp\u003eScrew machine length bits are shorter than jobber-length bits, making them the standard choice for drill presses, CNC machining centers, turret lathes, and screw machines where rigidity and minimal deflection are critical. This bit is suited for production shops, tool-and-die work, and maintenance applications involving hard or work-hardening materials. The 2.5xD flute-to-diameter ratio keeps the tool compact and stiff. It is a right-hand cut, regular spiral design with a straight cylindrical shank that seats directly in standard drill chucks or collet holders without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM41 cobalt high-speed steel construction for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and eliminates walking\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.0625 inches overall) for maximum rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute with tapered web for efficient chip clearing\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; rated for heavy-duty, high-performance use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or production-use bit for any application requiring a Wire Size 26 (0.147 inch) screw machine length drill bit with a straight cylindrical shank, conforming to ANSI standards for Series M41CO cobalt tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a drill press, CNC machine, or turret lathe with a properly sized chuck or collet rated for the shank diameter. Secure the shank fully and verify runout before cycling. Use cutting fluid or coolant appropriate for the workpiece material to preserve edge life, noting that this bit does not support coolant-through delivery.
