Built to Series 6300 specifications, it features a 5.60mm diameter, a 140-degree split point, and a right-hand spiral flute with R-thinned web geometry. The straight-cylindrical shank provides secure chuck engagement. Solid carbide construction delivers the rigidity and wear resistance needed for production-rate drilling in steel, alloy steel, and cast iron. This bit is suited for machinists and tool and die professionals running CNC machining centers or manual drill presses where hole accuracy and tool life are priorities.\u003c\/p\u003e\u003cp\u003eThe 8670560 is intended for use in screw machine and short-hole drilling applications where a compact flute length and stiff tool body improve straightness and reduce deflection. Its 2xD flute-to-diameter ratio and tapered web configuration make it well-suited for drilling into steel, alloy steel, and cast iron in both job shop and production environments. The coated finish supports heat dissipation and extended cutting life under continuous use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5.60mm diameter with a diameter tolerance of +0 to -0.018mm for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle for self-centering entry and reduced thrust in hard materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eR-thinned web with tapered web configuration reduces cutting forces at the chisel edge\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design promotes chip evacuation in screw machine length applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance screw machine length drill bit for use in steel, alloy steel, and cast iron workpieces.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Carbide is brittle — avoid lateral loading, interrupted cuts without proper parameters, or dropping the bit on hard surfaces. Follow the machine manufacturer and OSG Series 6300 recommendations for RPM and feed rate based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5.60mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Length\u003c\/strong\u003e: 28.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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 -0.018mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDecimal Inch Size Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.7 inches L x 0.45 inches W x 0.35 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 8670560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744650920242,"sku":"8670560","price":101.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92ac2d2de290359753c194556239fb2a_81c1379c-4904-4622-89a7-eaf1ea884dd0.jpg?v=1788859525","url":"https:\/\/voomisupply.com\/products\/osg-8670560-screw-machine-drill-bit-5-60mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
