It features a 0.2811 inch (9\/32 inch) diameter, a 140-degree split point, and a right-hand spiral flute configuration. The shorter screw machine length body provides rigidity and reduces deflection in high-speed production setups. R-thinned web geometry lowers thrust force and improves chip evacuation. Coolant-through capability supports extended tool life in deep-hole operations. This bit is suited for machinists, toolroom operators, and production drilling technicians working with ferrous and exotic materials.\u003c\/p\u003e\n\u003cp\u003eThe OSG 650028011 is engineered for cutting steel, alloy steel, cast iron, titanium, and titanium alloys. Its 3xD flute-to-diameter ratio and regular spiral flute geometry make it a practical choice for CNC machining centers, drill presses, and manual mills where a stiff, short-length bit is needed. The straight-cylindrical shank fits standard drill chucks and collet holders without modification. Series 6500 identifies this as part of OSG high-performance carbide drill lineup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces walking and improves entry in steel and alloy steel\u003c\/li\u003e\n  \u003cli\u003eR-thinned, tapered web lowers cutting thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports heat management in production drilling\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body minimizes deflection in high-speed applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual drilling equipment with standard straight-cylindrical chuck or collet systems.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to side loading. Power down and de-energize the machine spindle before changing tooling. Always apply appropriate cutting fluid or coolant when drilling ferrous metals and titanium alloys to prevent premature tool wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2811 inches (9\/32 inch, 7.14 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm (approximately 1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 94.00 mm (approximately 3.70 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.115 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.8 x 0.5 x 0.45 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 650028011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748161388850,"sku":"650028011","price":242.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_2e0a91f4-5c2a-4746-bf7c-70c3c1c21b0d.jpg?v=1788889813","url":"https:\/\/voomisupply.com\/products\/osg-650028011-carbide-screw-machine-drill-bit-0-2811-in","provider":"Voomi Supply","version":"1.0","type":"link"}
