It features a 140-degree split point, right-hand spiral flute geometry, and a straight-cylindrical shank measuring 8.00 mm in diameter. The R-thinned web reduces thrust and improves centering without a separate spotting operation. At 0.2402 inches (6.10 mm) in diameter, this bit fits the 0.2000 to 0.2500 inch size range of the OSG 6300 Series. A coated finish extends tool life in abrasive cuts. Diameter tolerance holds to +0 to -0.022 mm, making it suitable for close-tolerance hole requirements in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for machining steel, alloy steel, and cast iron in screw machine and CNC lathe or mill applications. The screw machine length format provides added rigidity compared to jobber-length bits, reducing deflection in short-reach setups. The 2xD flute-to-diameter ratio and tapered web configuration support efficient chip evacuation in moderate-depth holes. It is well suited for production drilling, component manufacturing, and toolroom use where consistent hole quality and tool life are critical. No coolant-through capability is present, so external flood or mist cooling should be applied when drilling at high speeds or feeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with R-thinned web for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eCoated finish extends cutting life in steel and alloy steel applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides increased stiffness over jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.022 mm supports close-tolerance hole production\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the OSG 6300 Series, designed for drilling steel, alloy steel, and cast iron workpieces.

Secure the shank fully in a collet or drill chuck to the recommended engagement depth before running the spindle. Power down and de-energize the machine before changing tooling. Do not run this bit in materials outside its rated workpiece range, and apply adequate external coolant when operating at elevated speeds to prevent thermal damage to the carbide substrate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2402 inches (6.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm (3.11 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm (1.34 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 pounds\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: 8670610\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736272929074,"sku":"8670610","price":107.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/040010d67133b60e6ed22726ce9083c9.jpg?v=1788776907","url":"https:\/\/voomisupply.com\/products\/osg-8670610-screw-machine-drill-bit-0-2402-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
