Sized at Letter E (0.2500 inch), it fits a 1MT spindle and features a 118-degree standard point with web thinning for reduced thrust and easier entry. The flute length measures 2.875 inches and overall length is 6.125 inches. Constructed from high-speed steel with an oxide finish, this bit is suited for general-purpose drilling in metal, wood, and similar materials. It conforms to ASME B94.11M standards and cuts in a right-hand direction with a regular spiral flute pattern.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in drill presses, milling machines, lathes, and other machine tools equipped with a No. 1 Morse taper spindle or adapter. The taper shank design is common in production and job-shop environments where positive drive and quick tool changes are prioritized. It is appropriate for general-purpose drilling applications in ferrous and non-ferrous metals, plastics, and similar workpiece materials. Machinists, toolroom technicians, and maintenance professionals will find this bit suitable for standard drilling tasks where a standard-point, spiral-flute geometry is called for.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter E size (0.2500 inch) with a diameter tolerance of +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eNo. 1 Morse taper (1MT) shank provides a self-locking, positive drive connection in compatible spindles\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point with web thinning reduces cutting thrust and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for general-purpose durability\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute, right-hand cutting direction suitable for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit drill bit for machine tools equipped with a No. 1 Morse taper (1MT) spindle socket or adapter sleeve.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom personnel on machine tools with a compatible 1MT spindle. Before inserting or removing the taper shank, power down and lock out the machine per OSHA lockout\/tagout procedures. Clean both the taper shank and spindle bore of chips and oil before seating to ensure full contact and prevent slippage. Do not use this bit in hand-held drilling equipment; taper shank bits require a machine spindle for safe operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: Letter E (0.2500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 1MT\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 with web thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.125 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\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: C12091\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51701882716466,"sku":"C12091","price":44.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dbf11dfd75702b5ecc2df24a5258add_6c3ae23c-86d4-422d-8232-36f87a549648.jpg?v=1788406478","url":"https:\/\/voomisupply.com\/products\/cleveland-c12091-taper-shank-drill-bit-letter-e-1mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
