Built from M42 cobalt high-speed steel, it carries a No. 4 wire gauge designation with a decimal diameter of 0.2090 inches. The 135-degree split point with web thinning reduces thrust force and enables self-centering on contact, minimizing the need for a center punch. At 2.375 inches overall length, this short-flute design provides rigidity in drill press, CNC, and turret lathe setups. The parabolic flute geometry promotes efficient chip evacuation. It is sized for use by machinists and maintenance technicians working with ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThe C15294 targets production drilling environments where stub-length rigidity and cobalt heat resistance are required. Primary workpiece materials listed include alloy steel and aluminum. The straight-cylindrical shank at 0.2090 inches diameter fits standard drill chucks and collet holders without modification. The 1.25-inch flute length accommodates moderate hole depths typical of screw machine and short-run production work. This series is sold individually per package, with a minimum order quantity of 10 units, making it suited for shop stocking or production line replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for extended tool life in abrasive and high-heat drilling conditions\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry accelerates chip removal and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides increased rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eParallel web configuration and coated finish extend cutting edge durability\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and ANSI specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement screw machine drill bit for use in standard drill chucks and collet systems accepting a 0.2090-inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and de-energized before changing tooling. Verify chuck or collet concentricity and tighten securely to the manufacturer torque specification for the holding device, not this bit.
