It measures 1-1\/8 inches in diameter with an 11-3\/4 inch overall length and a 7-1\/8 inch spiral flute length. The bit is manufactured from high-speed steel with an oxide finish and features a 3MT (Morse Taper 3) shank for secure, positive engagement in compatible drill presses and lathes. The 118-degree standard point with web thinning reduces thrust and improves chip evacuation on entry. This bit is designed for right-hand cutting with a regular spiral flute pattern, suitable for production and maintenance drilling operations.\u003c\/p\u003e\u003cp\u003eThe C12518 is used in machine shop, fabrication, and industrial maintenance environments where large-diameter holes are drilled in steel, cast iron, aluminum, and similar materials. The 3MT taper shank seats directly into taper-socket spindles on drill presses, lathes, and milling machines, eliminating the need for a separate chuck. This makes it a practical choice for shops and field maintenance crews that require consistent, repeatable large-bore drilling without auxiliary toolholding equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/8 inch diameter with a tight tolerance of +0.0000 to -0.0015 inches for accurate hole sizing\u003c\/li\u003e\n\u003cli\u003e3MT Morse Taper shank for direct spindle mounting on compatible machine tools\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction supports general-purpose cutting across a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning reduces entry thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eOxide finish provides mild corrosion resistance and reduces friction at the cutting interface\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute design per ASME B94.11M standard; Series 2411\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill press spindles, lathes, and milling machine quills with a No. 3 Morse Taper socket.

Before mounting, clean the taper shank and spindle socket thoroughly to remove chips, oil, and debris that could cause runout. Insert the shank firmly into the spindle socket and seat it with a moderate upward tap using a rubber mallet — never use the spindle quill feed to force-seat the taper. To remove, use the appropriate drift key in the spindle slot; do not strike the bit directly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11-3\/4 inches (11.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7-1\/8 inches (7.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper\u003c\/strong\u003e: 3MT (Morse Taper No. 3)\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\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 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 -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2411\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C12518\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51710433460530,"sku":"C12518","price":249.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97ec02281711929023cf67b857b77442.jpg?v=1788466908","url":"https:\/\/voomisupply.com\/products\/cleveland-c12518-taper-shank-drill-bit-1-1-8-in-3mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
