Built from cobalt high speed steel with a coated finish, it delivers strong heat and wear resistance in demanding cutting conditions. The bit features a 130-degree point angle, a 2-flute spiral configuration, and an R-thinned web for improved penetration and reduced thrust. At 0.242 inches (letter size C, 6.15 mm) in diameter with an overall length of 3-3\/16 inches, this bit is suited for short-reach, high-precision drilling. Installed and used by machinists, tool-and-die techs, and maintenance professionals working with steel and alloy steel.\u003c\/p\u003e\u003cp\u003eThis screw machine length drill bit is engineered for use in steel and alloy steel workpieces where a stub-length format is preferred for rigidity and runout control. The straight-cylindrical shank fits standard drill chucks and quick-change tooling systems. Its 1-3\/8-inch flute length, 3xD flute-to-diameter ratio, and tapered web configuration make it well suited for production drilling environments and CNC machining centers where tool stiffness and consistent hole quality are priorities. The Series 1000 designation places it in OSG high performance tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for heat resistance and durability in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with R-thinned web reduces thrust and improves centering\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length format increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and quick-change systems\u003c\/li\u003e\n\u003cli\u003eCoated finish extends tool life in abrasive cutting conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for applications requiring a 0.242-inch (letter C) screw machine length bit in steel and alloy steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and maintenance technicians using standard drill chucks or collet-style toolholders. Ensure the shank is fully seated and the chuck is properly tightened before operation. Use appropriate cutting fluid or coolant for steel applications to manage heat buildup, as this bit does not support through-coolant. Inspect the cutting edges for wear before each use to maintain hole quality and dimensional tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.242 inches (Letter C, 6.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/8 inches (34.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Type\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.041 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10242005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747264921906,"sku":"10242005","price":69.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d00724ce297b3d3a0e30e292a4aabf94.jpg?v=1788878361","url":"https:\/\/voomisupply.com\/products\/osg-10242005-screw-machine-drill-bit-0-242-in-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
