It features a 135-degree split point, a Ti-NAMITE-X (TX) proprietary finish, and a web-thinned tip geometry for fast penetration and reduced thrust. The straight cylindrical shank measures 0.230 inches in diameter, and the overall length is 3.583 inches. With coolant-through capability and a micrograin carbide grade, this bit is built for production environments where tool life and hole quality matter. It is suited for machinists, tool-and-die professionals, and maintenance technicians running CNC or manual drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit fits applications requiring precision hole making in ferrous and non-ferrous metals, stainless steel, cast iron, and other difficult-to-machine materials. The 5xD flute-to-diameter ratio supports deeper cuts relative to the bit diameter. The two-flute spiral design promotes efficient chip evacuation. It is appropriate for use in CNC machining centers, drill presses, and manual machines where coolant delivery is available. The SGS Series 142P designation and DIN 6537 specification make it a recognized standard in industrial tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web-thinned tip reduces walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X (TX) finish improves wear resistance and heat management\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed production drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flutes for consistent chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose jobber drill for industrial drilling applications conforming to DIN 6537 specifications in the 0.300 to 0.350 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or tooling technicians.
