Built to Series 6530 standards, it features a 140-degree split point geometry with X-thinned web construction that reduces thrust force and improves centering on entry. The EgiAs coating provides enhanced wear resistance and heat dissipation, extending tool life in difficult-to-machine materials. At 7.2 mm in diameter with a 10xD flute-length-to-diameter ratio, this bit is suited for deep-hole applications where rigidity and chip evacuation are both critical factors. Licensed machinists, toolroom technicians, and CNC operators are the typical end users.\u003c\/p\u003e\u003cp\u003eThis drill bit is applied in precision machining environments including CNC machining centers, drill presses, and manual mills where taper length reach is required. The straight cylindrical shank at 8.00 mm diameter seats securely in standard drill chucks and collet-style toolholders. Coolant-through capability makes it effective in high-speed production runs on materials such as alloy steels, stainless steels, and cast irons where internal cooling is necessary to maintain surface finish and tool life at depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior rigidity and wear resistance compared to HSS alternatives\u003c\/li\u003e\n\u003cli\u003eEgiAs coating enhances heat resistance and reduces tool wear in abrasive and hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree split point reduces walking and lowers entry thrust force\u003c\/li\u003e\n\u003cli\u003eX-thinned web geometry improves chip flow and reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed deep drilling with internal coolant delivery\u003c\/li\u003e\n\u003cli\u003e10xD flute-to-diameter ratio provides extended reach for taper length applications\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 standard drill chucks and collet toolholders accepting an 8.00 mm straight cylindrical shank across CNC and manual drilling platforms.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle at a full stop and machine power locked out. Ensure the shank seating surface and toolholder bore are clean and free of chips before securing the bit. Verify coolant-through lines are clear and delivering adequate flow before beginning deep-hole cycles. Consult machine tool manufacturer guidelines for recommended speeds and feeds when running solid carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6530\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.2 mm (0.2835 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\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 155 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\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 10xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.25 inches L x 0.55 inches W x 0.45 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: 653028312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728036856114,"sku":"653028312","price":323.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87f7ff7c8fa7b0a8efc9ab21e88b1f0e_2c868dd4-2e2f-4f48-ab90-f7102551ec8a.jpg?v=1788686707","url":"https:\/\/voomisupply.com\/products\/osg-653028312-taper-length-drill-bit-7-2mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
