It measures 7.00 mm (0.2756 inches) in diameter with an overall length of 88.00 mm (3.46 inches) and a flute length of 35.00 mm (1.38 inches). The 140-degree split point and R-thinned web reduce thrust force and improve centering on entry. Two spiral flutes with a 3xD flute-to-diameter ratio evacuate chips efficiently. Coolant-through capability supports high-speed runs in ferrous and exotic materials. A licensed machinist or tool-and-die professional typically installs this bit in CNC machining centers, drill presses, or screw machine setups.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for cutting steel, alloy steel, cast iron, titanium, and titanium alloys. Its screw machine length profile keeps the tool short and rigid, reducing deflection in tight-tolerance bores. The straight cylindrical shank seats in standard drill chucks and collets without modification. It fits production drilling applications where dimensional consistency and tool life are critical, and it falls within the 0.2500 to 0.3000 inch (6.50 to 8.00 mm) diameter size range of the OSG Series 6500 family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with R-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed, deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes at 3xD ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eScrew machine length profile maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0 to -0.022 mm for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces.

Secure the shank fully in the chuck or collet before operation and verify runout before cutting. When using coolant-through capability, confirm the machine spindle and toolholder support internal coolant delivery at the required pressure. Avoid shock loading or intermittent cuts that can chip carbide cutting edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 88.00 mm (3.46 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 35.00 mm (1.38 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.00 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\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 By Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2500 to 0.3000 inches (6.50 to 8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.55 inches L x 0.5 inches W x 0.45 inches H\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: 8690700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737162875186,"sku":"8690700","price":228.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d0d9f99e2868d1676c08b5fb762a65f.jpg?v=1788785103","url":"https:\/\/voomisupply.com\/products\/osg-8690700-screw-machine-drill-bit-0-2756-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
