Built to Series 6300 specifications, it features a 0.122 inch (3.10 mm) diameter, a 140-degree split point, and a two-flute spiral configuration with X-thinned web geometry. The straight cylindrical shank measures 4.00 mm in diameter and seats securely in standard drill chucks or collet holders. At 66.00 mm overall length, the screw machine format provides a short, rigid profile that minimizes deflection in production drilling and CNC machining environments. Licensed machinists and tool and die technicians are the primary installers and operators of this bit.\u003c\/p\u003e\u003cp\u003eThe OSG 8670310 is suited for drilling steel, alloy steel, and cast iron in both manual and CNC applications. The screw machine length format is well matched to turret lathes, machining centers, and drill presses where stub-length rigidity is required. The 2xD flute-to-diameter ratio and regular spiral geometry support efficient chip evacuation in short-depth holes. This bit is positioned for production environments where precision hole tolerance and tool consistency are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eX-thinned web with tapered web configuration reduces cutting force at entry\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design promotes chip evacuation in short-depth holes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eCoated finish for extended tool life in steel and cast iron applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling steel, alloy steel, and cast iron workpieces.

Ensure the machine spindle and workpiece are fully secured before engaging the bit. Carbide tooling is brittle and should not be subjected to interrupted cuts or side loading beyond the tool design parameters. Inspect the cutting edge and shank for damage before each use and replace immediately if chipping or wear is detected.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.122 inches (3.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (approximately 2.60 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 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\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\u003eWeb Thinning\u003c\/strong\u003e: X-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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 8670310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731160760626,"sku":"8670310","price":108.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d34e3c221b9812828d6c89564d2208d.jpg?v=1788727754","url":"https:\/\/voomisupply.com\/products\/osg-8670310-screw-machine-drill-bit-0-122-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
