It features a 140-degree split point with X-thinned web geometry, which reduces thrust force and improves centering on entry without a pilot hole. The EgiAs finish enhances surface hardness and lubricity for extended tool life in ferrous and non-ferrous materials. Coolant-through capability delivers cutting fluid directly to the cutting edge, making this bit well suited for CNC machining centers and drilling stations where heat management is critical. Machinists and tooling specialists are the primary installers and users of this bit.\u003c\/p\u003e\u003cp\u003eThis drill bit belongs to OSG Series 6540 and is designed for deep-bore operations where standard-length bits cannot reach. With a flute-to-diameter ratio of 20xD and a 170 mm flute length, it handles deep features in molds, dies, fixtures, aerospace components, and precision mechanical assemblies. The straight cylindrical shank at 5\/16 inch diameter allows direct chucking in standard drill chucks and collets without adapter sleeves in most CNC and manual setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003e140-degree split point with X-thinned web reduces walking and entry thrust\u003c\/li\u003e\n\u003cli\u003eEgiAs coating improves surface lubricity and extends tool life\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels fluid directly to the cutting zone for heat control\u003c\/li\u003e\n\u003cli\u003e20xD flute-to-diameter ratio enables deep-hole drilling in a single tool\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, 2-flute configuration for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for CNC machining centers and drilling stations accepting a straight cylindrical shank with a 5\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists and CNC tooling technicians. Ensure the spindle and collet or chuck are fully de-energized and at a complete stop before changing tooling. Verify runout and chuck grip on the 5\/16 inch shank before initiating a drilling cycle. Follow machine manufacturer and facility safety guidelines for feeds, speeds, and coolant pressure when using coolant-through tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.055 inches (230.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.693 inches (170.00 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 20xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6540\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.2 inches L x 0.55 inches W x 0.45 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.205 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: 654028012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737111232818,"sku":"654028012","price":681.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fb5c0c3dd8b29b6bec8c30553aa0e01_8ea1ba08-3f7f-4e6a-b802-3cb2f076590e.jpg?v=1788784400","url":"https:\/\/voomisupply.com\/products\/osg-654028012-extra-length-drill-bit-0-2813-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
