Built from M42 cobalt high-speed steel, this bit handles tough workpiece materials including alloy steels and aluminum. It carries a No. 30 wire gauge size, which corresponds to 0.1285 inches in decimal. The 135-degree split point reduces walking and allows drilling to begin without a center punch. A parabolic flute geometry promotes efficient chip evacuation. The bit conforms to ASME B94.11M standards and is rated as heavy duty grade, making it a reliable choice for machinists and tool-and-die technicians working on close-tolerance applications.\u003c\/p\u003e\u003cp\u003eThis screw machine length drill bit is suited for production drilling operations in both shop and field environments. Its shortened overall length of 1-15\/16 inches provides added rigidity compared to jobber-length bits, reducing deflection in tight clearance setups. The straight-cylindrical shank fits standard drill chucks and collet holders. Typical applications include drilling alloy steel components and non-ferrous materials such as aluminum where heat resistance and bit longevity are critical factors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt tool material for superior heat resistance and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement\u003c\/li\u003e\n\u003cli\u003eParabolic flute design improves chip flow and reduces heat buildup in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web configuration lowers cutting resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (1-15\/16 inches OAL) provides rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0007 inches for precise, repeatable hole sizing\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and ANSI specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or stock drill bit for any standard drill chuck or collet system accepting a 0.1285-inch straight-cylindrical shank, consistent with No. 30 wire gauge screw machine length tooling in Series 2175.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling technician familiar with rotating cutting tools. Ensure the drill chuck or collet is fully tightened and the shank is fully seated before operating. Always power down and lock out the machine before changing bits.
