Measuring 4.50mm (0.1772 inches) in diameter with an overall length of 140mm (5.51 inches) and a flute length of 85mm (3.35 inches), this bit delivers the reach needed for deep-hole work where standard-length tooling falls short. The 140-degree split point reduces thrust and improves entry accuracy, while the X-Thinned web geometry minimizes walking on entry. Applied with an EgiAs finish, the bit is suited for high-speed, high-precision drilling cycles. It is typically installed by machinists and CNC operators in production and toolroom environments.\u003c\/p\u003e\u003cp\u003eThis extra length drill bit is designed for deep-hole drilling operations in materials including steel, stainless steel, cast iron, and similar workpiece materials common in manufacturing and precision machining. The 15xD flute-to-diameter ratio provides extended reach without sacrificing chip evacuation. Coolant-through capability supports continuous cutting cycles in high-output CNC machining centers and drill presses where internal coolant delivery is available. Right-hand cutting direction makes it compatible with conventional spindle rotation on standard machine tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance for hard-material drilling\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n\u003cli\u003eX-Thinned web geometry minimizes cutting resistance and material deformation at entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, deep-hole drilling with internal coolant delivery\u003c\/li\u003e\n\u003cli\u003eEgiAs finish enhances surface hardness and tool life in abrasive cutting conditions\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with 6.00mm shank diameter fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and multi-spindle equipment accepting straight-cylindrical shank drill bits with a 6.00mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or CNC operators familiar with cutting tool setup and machine operation. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before loading or changing tooling. Secure the shank fully within the collet or chuck to the recommended grip length before engaging the workpiece. Verify coolant supply lines are clear and delivering adequate flow when using the coolant-through feature during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 4.50mm (0.1772 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 140mm (5.51 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 85mm (3.35 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00mm\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.115 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241637\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: 8712450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746377204018,"sku":"8712450","price":479.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87f7ff7c8fa7b0a8efc9ab21e88b1f0e_11bc6b11-efb9-42a5-9fcd-422910f891a0.jpg?v=1788869200","url":"https:\/\/voomisupply.com\/products\/osg-8712450-extra-length-solid-carbide-drill-bit-4-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
