Built from high-speed steel with an oxide finish, it accepts a 3MT (Morse taper) shank for secure seating in compatible drill presses, lathes, and machining centers. The bit measures 15\/16 inch (0.9375 inch) in diameter with a 118-degree standard point angle and web-thinned geometry that reduces thrust and improves chip clearance at entry. With a flute length of 6.125 inches and an overall length of 10.75 inches, it handles moderate-depth through-hole and blind-hole applications. Cutting direction is right-hand with a regular spiral flute pattern. This bit is intended for installation and use by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThe C12243 is suited for general-purpose production drilling where a Morse taper interface is required. Typical applications include drilling on floor-standing drill presses, manual lathes with tailstock chucks, and milling machines fitted with a 3MT adapter. It performs well in ferrous metals, aluminum, and plastics at moderate speeds and feeds. The oxide finish provides a baseline level of lubricity and corrosion resistance for shop environments. This bit conforms to ASME B94.11M standards, making it appropriate for toolrooms, maintenance shops, and production floor use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15\/16 inch diameter (0.9375 inch decimal) with a diameter tolerance of +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e3MT Morse taper shank for direct mounting in compatible drill presses, lathes, and machining centers\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned geometry for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for general-purpose durability\u003c\/li\u003e\n  \u003cli\u003eRegular right-hand spiral flute, 6.125 inches long, for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose taper shank drill bit compatible with any machine spindle or tailstock chuck accepting a 3MT (No. 3 Morse Taper) interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified tool operators. Before mounting, ensure the machine spindle is fully stopped and de-energized. Clean both the shank taper and the spindle socket to remove chips and oil before seating to ensure proper taper contact. Use a drift and mallet against the drift slot to remove the bit; never use impact force against the cutting end or flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/16 inch (0.9375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper\u003c\/strong\u003e: 3MT (No. 3 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, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.75 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: Regular Spiral, Right-Hand Cut\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 -0.0012 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C12243\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699888619826,"sku":"C12243","price":140.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dbf11dfd75702b5ecc2df24a5258add_24749b9b-4352-4294-979d-848ec1b8da18.jpg?v=1788382628","url":"https:\/\/voomisupply.com\/products\/cleveland-c12243-taper-shank-drill-bit-15-16-in-3mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
