Built to Series 6300 standards, it features a 6.2 mm cutting diameter (0.2441 inch), a 140-degree point angle with R-thinned web geometry, and a coated finish that extends tool life in demanding production environments. The straight-cylindrical shank measures 8.00 mm in diameter, and the overall length is 79.00 mm (3.11 inches). With a 34.00 mm flute length and a 2xD flute-to-diameter ratio, this bit is suited for short, stable cuts in tight tolerances. Machinists and toolroom technicians working in CNC and manual drilling applications install this bit where rigidity and precision are required.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on steel, alloy steel, and cast iron workpieces. The screw machine length body keeps overhang minimal, improving rigidity and reducing deflection when drilling in high-cycle production setups. The right-hand spiral flutes and tapered web configuration support efficient chip evacuation. This bit fits applications where a compact, stiff drill geometry outperforms jobber-length alternatives, particularly on machining centers, drill presses, and turret lathes operating at production volumes.\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 point angle with R-thinned web reduces entry force and improves centering\u003c\/li\u003e\n\u003cli\u003eCoated finish extends tool life under continuous cutting conditions\u003c\/li\u003e\n\u003cli\u003eScrew machine length body minimizes overhang and deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets accepting 8.00 mm shanks\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral and tapered web for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for machining applications in steel, alloy steel, and cast iron.

Secure the shank fully in a matched collet or drill chuck before operation and verify runout is within acceptable limits, as solid carbide is more brittle than high-speed steel and sensitive to side loading. Power down and lock out the machine spindle before changing tooling. Follow the machine manufacturer and tooling supplier recommendations for speeds, feeds, and coolant strategy appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.2 mm (0.2441 inch)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\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\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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 8670620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730409914674,"sku":"8670620","price":107.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92ac2d2de290359753c194556239fb2a_eab24feb-c556-4968-b9ba-206bb8cbf70a.jpg?v=1788716959","url":"https:\/\/voomisupply.com\/products\/osg-8670620-carbide-screw-machine-drill-bit-6-2-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
