Built from cobalt high-speed steel with a WXL finish, this bit handles harder workpiece materials and elevated cutting temperatures with better wear resistance than standard HSS tooling. It features a 120-degree drill point angle, right-hand spiral flute configuration, and R-thinned web geometry that reduces thrust force at entry. The straight-cylindrical shank seats directly in standard drill chucks or collet holders without adapters. Machinists, tool-and-die technicians, and metalworking tradespeople are the primary users of this bit.\u003c\/p\u003e\u003cp\u003eThis drill bit suits production drilling, maintenance, and fabrication environments where access depth or workpiece thickness exceeds standard drill length capacity. The 15xD flute-to-diameter ratio provides extended reach while the two-flute spiral design promotes consistent chip evacuation in ferrous and non-ferrous metals. It is well suited for use in drill presses, CNC machining centers, and handheld power drills where a straight-cylindrical shank is accepted. No coolant-through capability is present, so external coolant or cutting oil applied at the entry point is recommended when drilling hardened or heat-sensitive materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat and wear resistance over standard HSS bits\u003c\/li\u003e\n\u003cli\u003eWXL finish reduces friction and extends tool life in metalworking applications\u003c\/li\u003e\n\u003cli\u003e120-degree split point angle for accurate self-centering entry without a center punch\u003c\/li\u003e\n\u003cli\u003eR-thinned web reduces axial thrust and prolongs cutting edge life\u003c\/li\u003e\n\u003cli\u003eTwo-flute right-hand spiral design promotes reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003e15xD flute-to-diameter ratio provides extended reach for deep-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard straight-cylindrical shank extra length drill bits in the 0.063-inch diameter class, compatible with any drill chuck or collet holder accepting a 2 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully within the chuck or collet to the recommended engagement depth before beginning any drilling operation. Ensure the workpiece is clamped or fixtured to prevent movement under cutting load. Apply a suitable cutting fluid or oil when drilling ferrous metals to manage heat buildup, particularly given the absence of coolant-through channels. Inspect the cutting edges for wear or chipping before each use, and replace the bit if edge geometry is compromised to avoid workpiece damage or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.063 inches (1.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WXL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 8623016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753359343922,"sku":"8623016","price":59.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db8bf4eab9c5a3586e50c713caca40ea.jpg?v=1788935788","url":"https:\/\/voomisupply.com\/products\/osg-8623016-extra-length-cobalt-drill-bit-0-063-in","provider":"Voomi Supply","version":"1.0","type":"link"}
