It carries a No. 1 Morse taper (1MT) shank for secure seating in compatible drill presses, lathes, and taper-socket holders. The bit is ground from high-speed steel with an oxide finish for baseline corrosion resistance. A 118-degree standard point and right-hand spiral flute make this a conventional, versatile choice for production and maintenance drilling. Web thinning reduces entry force and improves chip evacuation at the cutting tip. Overall length is 6.375 inches with a flute length of 3.125 inches, giving adequate reach for most standard drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for machine shop, maintenance, and light manufacturing environments where a 1MT taper-socket spindle is available. Typical applications include through-hole and blind-hole drilling in mild steel, aluminum, brass, and thermoplastics. The 19\/64-inch diameter (0.2969 inches decimal) fills a common fractional size used in bolt clearance, tapping prep, and fixture work. It conforms to ASME B94.11M, the standard governing straight and taper shank twist drills. Machinists, maintenance technicians, and toolroom operators are the primary users of this style and size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 1 Morse taper shank seats directly in 1MT drill press spindles and lathe tailstocks without an adapter\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles general-purpose drilling across a wide range of common materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point geometry provides consistent entry on flat and curved workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tip lowers thrust requirements and improves chip flow at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides light surface protection during storage and use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute — compatible with conventional spindle rotation on standard machine tools\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M dimensional and tolerance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for any machine spindle or tool holder accepting a No. 1 Morse taper shank drill bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1MT taper socket in the machine spindle or a dedicated Morse taper sleeve adapter. Power down and lock out the machine before seating or removing the bit. Drive the taper firmly into the socket with a soft mallet to ensure full engagement, and use a drift key through the spindle slot to release it cleanly without damage to the shank. Confirm spindle speed is appropriate for the workpiece material and bit diameter before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/64 inches (0.2969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 1MT (No. 1 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2410\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C12117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51701047525682,"sku":"C12117","price":48.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dbf11dfd75702b5ecc2df24a5258add_6a29a04f-3921-4025-ba06-4c4d9162510c.jpg?v=1788397389","url":"https:\/\/voomisupply.com\/products\/cleveland-c12117-taper-shank-drill-bit-19-64-in-1mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
