It features a 140-degree split point geometry and an EgiAs coating finish, which helps reduce friction and extend tool life in high-cycle production environments. The bit has a 0.2520-inch (6.40 mm) diameter, a straight shank with an 8.00 mm shank diameter, and an overall length of 125.00 mm (approximately 4.92 inches). The spiral flute design with X-thinned web promotes efficient chip evacuation and reduces thrust force during entry. Coolant-through capability allows internal coolant delivery directly to the cutting zone, supporting deep-hole drilling applications. This bit is sold individually as a single unit.\u003c\/p\u003e\u003cp\u003eThe OSG 8704640 is suited for machine shop production drilling, CNC machining centers, and precision toolroom work. The 8xD flute-length-to-diameter ratio and taper length configuration make it appropriate for applications requiring greater depth reach than a jobber-length bit provides. Right-hand cutting direction is standard for conventional drill press and CNC spindle use. This bit is typically installed and operated by machinists and CNC operators working with ferrous and non-ferrous materials in industrial production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in high-speed drilling\u003c\/li\u003e\n\u003cli\u003eEgiAs coating finish reduces friction and improves tool life\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle for aggressive entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers cutting fluid directly to the tip for deep-hole applications\u003c\/li\u003e\n\u003cli\u003eX-thinned web geometry reduces walking and improves chip flow\u003c\/li\u003e\n\u003cli\u003e8xD flute-length-to-diameter ratio provides extended reach beyond standard jobber length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement taper length drill bit within the OSG Series 6520 product line.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet or chuck acceptance of the 8.00 mm straight shank before tightening. When using the coolant-through feature, confirm that the machine tool coolant supply is properly connected and set to appropriate pressure for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2520 inches (6.40 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\/Finish\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 125.00 mm (approximately 4.92 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6520\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8704640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728759423282,"sku":"8704640","price":267.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05777040c54e7cc3a2761962bca80aec_d2bde84a-c575-44cd-8474-2bb72591252a.jpg?v=1788695926","url":"https:\/\/voomisupply.com\/products\/osg-8704640-taper-length-drill-bit-0-2520-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
