Built to Series 2175A specifications, this bit features a 135-degree split point for fast, accurate starts with minimal walking. The parabolic flute geometry promotes efficient chip evacuation, while the M42 cobalt construction provides heat resistance and extended tool life when cutting harder materials. The overall length is 2.25 inches, making it well suited for close-quarters drilling on drill presses, CNC machines, and manual setups. Installation and use are handled by machinists, tool and die professionals, and general metalworking tradespeople.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for drilling alloy steel and aluminum in production and maintenance environments where short overall length is required for rigidity and clearance. The screw machine length profile reduces deflection compared to jobber-length bits, making it a reliable choice for repetitive hole patterns and precision work. The straight-cylindrical shank accepts standard drill chucks without modification. Web-thinned construction lowers thrust requirements and improves penetration efficiency on tougher workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 9 (0.1960 inches) with diameter tolerance of +0.0000 to -0.0007 inches for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and allows fast penetration without a center punch\u003c\/li\u003e\n\u003cli\u003eM42 cobalt material grade provides elevated heat and wear resistance for extended service life\u003c\/li\u003e\n\u003cli\u003eParabolic flute design with web thinning improves chip flow and lowers cutting thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.25 inches OAL) delivers added rigidity in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight-cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit compatible with standard drill chucks accepting a 0.1960-inch straight-cylindrical shank, suitable for alloy and aluminum workpiece materials per Series 2175A specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and metalworking tradespeople using standard drill presses, CNC drilling equipment, or hand drills with compatible chucks. Secure the workpiece firmly before drilling and ensure the chuck is properly tightened to prevent shank slippage. Always power down and de-energize the machine before changing tooling.
