Built from cobalt high-speed steel with a WXL finish coating, this bit handles elevated cutting temperatures without losing hardness at the cutting edge. The 120-degree split point with R-thinned web reduces thrust and improves centering without a pilot hole. At 2.10 mm (0.0827 inches) in diameter with an 80 mm overall length and a 38 mm flute length, this bit is suited for extended-reach applications where standard-length tooling cannot reach. Right-hand spiral flute geometry clears chips efficiently during through-drilling operations. Licensed machinists, toolmakers, and precision fabricators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in CNC machining centers, manual drill presses, and handheld drilling applications where deep or hard-to-access hole locations require extra reach. The 2.00 mm straight cylindrical shank fits standard collets and chucks without modification. The 15xD flute-to-diameter ratio supports deep-hole drilling in stainless steel, high-nickel alloys, titanium, and hardened ferrous materials where standard HSS tooling fails prematurely. It is also suitable for production drilling in aerospace, medical device, and precision instrument manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction resists heat buildup and maintains edge hardness in hard, work-hardening alloys\u003c\/li\u003e\n  \u003cli\u003eWXL finish coating reduces friction and extends tool life in demanding applications\u003c\/li\u003e\n  \u003cli\u003e120-degree drill point angle with R-thinned web lowers entry thrust and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eExtra length at 80 mm overall with 38 mm flute length provides reach for deep or recessed drilling\u003c\/li\u003e\n  \u003cli\u003e15xD flute-by-diameter ratio supports efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral, two-flute design compatible with standard drilling equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for applications requiring a 2.10 mm diameter extra-length cobalt drill bit with a 2.00 mm straight cylindrical shank in any collet or drill chuck accepting that shank size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling professional familiar with speeds and feeds for cobalt tooling in the target material. Secure the straight cylindrical shank fully in the collet or chuck before operation and confirm runout is within acceptable limits. Power down the spindle completely before changing tooling. Do not exceed the recommended cutting parameters for cobalt drill bits in the material being machined, as excessive feed rate or insufficient coolant can cause premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0827 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 38.00 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\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\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: R-Thinned\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 8623021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727298986290,"sku":"8623021","price":64.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd04e13a29827bcc78d99e9041c2a78f.jpg?v=1788676032","url":"https:\/\/voomisupply.com\/products\/osg-8623021-extra-length-cobalt-drill-bit-0-0827-in","provider":"Voomi Supply","version":"1.0","type":"link"}
