Built from high-speed steel with an oxide finish, it carries a 1.25 inch diameter and a 118-degree standard point angle with web thinning for reduced thrust at entry. The 4MT (Morse Taper 4) shank seats directly into compatible taper-socket spindles on drill presses, lathes, and radial arm machines, eliminating the need for a chuck. This bit is a general-purpose tool sized for production and maintenance machinists who drill large-diameter holes in ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThe C12279 is suited for stationary machine tool applications in industrial, manufacturing, and maintenance settings. Its 7.875 inch flute length provides adequate chip clearance during deep-hole passes, and the 13.5 inch overall length accommodates standard 4MT spindle setups. Right-hand spiral flutes eject chips efficiently in standard forward-rotation drilling operations. This bit is typically used in job shops, fabrication facilities, and plant maintenance operations where large-diameter through-holes and blind holes are required in structural or plate stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25 inch diameter with a diameter tolerance of +0.0000 to -0.0015 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e4MT (Morse Taper 4) shank for direct mounting in taper-socket spindles without a chuck\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning to reduce entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003eRegular right-hand spiral flutes for efficient chip evacuation in forward-rotation drilling\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M standards for drill bit geometry and dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, lathes, and other stationary machine tools equipped with a Morse Taper 4 spindle socket.

Power down and lock out the machine before seating or removing the taper shank. Clean both the shank and the spindle socket thoroughly before insertion to ensure full taper contact and prevent slippage under load. Do not use a standard drill chuck to hold a taper shank bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT (Morse Taper 4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 13.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.875 inches (7-7\/8 inches)\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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, 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\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: C12279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692826034482,"sku":"C12279","price":250.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dbf11dfd75702b5ecc2df24a5258add_0e0013e4-65c9-41fb-9c12-95acc94b4764.jpg?v=1788303578","url":"https:\/\/voomisupply.com\/products\/cleveland-c12279-taper-shank-drill-bit-1-1-4-in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
