It features a 140-degree split point angle with X-thinned web geometry, which reduces thrust and improves centering at the start of the cut. The 7.4 mm cutting diameter is paired with a straight cylindrical shank measuring 8.00 mm, making it compatible with standard drill chucks and tool holders. An EgiAs coating provides enhanced wear resistance and heat reduction at the cutting edge. This bit is installed and used by machinists, tool-and-die technicians, and maintenance mechanics working in production or job shop environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for taper length drilling operations in ferrous and non-ferrous metals, alloys, and other materials where extended flute reach is required beyond standard jobber length. The 81 mm flute length at an 8xD ratio supports chip evacuation in deeper holes. The right-hand spiral flute design and coolant-through capability make it well suited for CNC machining centers and manual drill press setups where through-spindle or through-tool coolant is available. It is packaged and sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with X-thinned web reduces walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eEgiAs coating extends tool life and reduces heat buildup at the cutting zone\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole applications\u003c\/li\u003e\n\u003cli\u003e8xD flute-to-diameter ratio provides extended reach with efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks without adaptation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style taper length drill bit for use in CNC machining centers, drill presses, and manual machine tools accepting a straight cylindrical shank with an 8.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup and machine operation. Secure the shank fully in a properly sized collet or drill chuck before operation, and confirm runout is within acceptable tolerance for the application. Ensure the machine spindle is at a full stop before changing or inspecting the tool. When using coolant-through capability, verify that coolant pressure and flow rate are compatible with the machine spindle and tool holder system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.4 mm (0.2913 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: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 81 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 140 mm\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: 8.00 mm\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\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.55 x 0.5 x 0.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.155 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: 8704740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730292146482,"sku":"8704740","price":390.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05777040c54e7cc3a2761962bca80aec_57a466a1-25bb-494f-a9bd-804c40d2ded6.jpg?v=1788714785","url":"https:\/\/voomisupply.com\/products\/osg-8704740-taper-length-drill-bit-7-4-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
