It carries a 2.50 mm (0.0984 inch) diameter, a 140-degree split point, and an X-thinned web that reduces thrust and improves centering on entry. The straight-cylindrical shank measures 4.00 mm in diameter and fits standard drill chucks without an adapter. At 62.00 mm overall length and a 14.00 mm flute length, this stub-length geometry provides extra rigidity compared to jobber-length bits, making it well-suited for precision hole-making on CNC machining centers and manual drill presses alike.\u003c\/p\u003e\u003cp\u003eThis bit is designed for production drilling in steel, alloy steel, and cast iron. The screw machine (stub) length format is a common choice in high-volume machining environments where reduced tool overhang minimizes deflection and improves hole location accuracy. The 2xD flute-to-diameter ratio and regular spiral flute geometry support efficient chip evacuation in short-depth holes. It does not include coolant-through capability, so it is best applied in operations where flood coolant or cutting oil is applied externally.\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 reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eX-thinned web reduces cutting resistance and heat buildup at the point\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with regular spiral flutes for consistent chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute design in OSG Series 6300\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.014 mm for tight hole-size control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSuited for drilling steel, alloy steel, and cast iron workpieces. Fits any drill chuck or collet accepting a 4.00 mm straight-cylindrical shank. Sized for applications within the 0.0000 to 0.1000 inch (0.00 to 3.50 mm) drill bit size range per the Series 6300 product family.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in a collet or drill chuck before operation and verify runout before starting a production run. Apply external flood coolant or cutting oil throughout the cut, as this bit does not support coolant-through delivery. Solid carbide is brittle relative to high-speed steel — avoid side loading, interrupted cuts without proper feed management, or cross-drilling into existing holes at an angle without a guide. Inspect the cutting edges for chipping between uses, as carbide micro-chipping may not be visible without magnification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62.00 mm (2.44 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 -0.014 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: 0.027 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: 8670250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749755224370,"sku":"8670250","price":103.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca5920429c45f49565e2455108ed0666.jpg?v=1788910036","url":"https:\/\/voomisupply.com\/products\/osg-8670250-screw-machine-drill-bit-0-0984-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
