Built to Series 6500 specifications, it features a 140-degree split point with R-thinned web geometry that reduces thrust force and improves centering on entry. The 7.50mm (0.2953 inch) diameter, two-flute spiral design with a straight-cylindrical shank promotes chip evacuation and consistent hole quality. Coolant-through capability supports extended tool life when running at elevated speeds. This drill is intended for use by machinists, tool-and-die professionals, and CNC operators working in production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling steel, alloy steel, cast iron, titanium, and titanium alloys in screw machine, CNC, and manual drilling setups. The screw machine length body keeps the tool compact and rigid, making it well matched to close-tolerance applications on machining centers, drill presses, and turret lathes. The right-hand spiral flute configuration and coated finish are optimized for consistent performance in high-cycle production runs where tool longevity and hole accuracy are critical.\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 and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with R-thinned tapered web for reduced entry thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design extends tool life and supports chip clearing at depth\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral configuration promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with 8.00mm shank diameter fits standard collets and chucks\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0 to -0.022mm supports consistent hole sizing within a 0.2500 to 0.3000 inch size range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in standard straight-shank drill chucks and collet holders accommodating an 8.00mm shank.

Ensure the machine spindle is fully stopped and locked out before loading or removing the drill. Verify that the collet or chuck is rated for the 8.00mm shank diameter and is free of debris before seating the tool. When using coolant-through capability, confirm coolant pressure and flow rate are within the machine and toolholder specifications before engaging the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2953 inches (7.50mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 94.00mm (approximately 3.70 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 38.00mm (approximately 1.50 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00mm\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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eSeries\u003c\/strong\u003e: 6500\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: 8690750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730289426738,"sku":"8690750","price":187.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_8ca0e5a8-7060-49f3-8f76-111123ea9b04.jpg?v=1788714729","url":"https:\/\/voomisupply.com\/products\/osg-8690750-solid-carbide-screw-machine-drill-bit-7-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
