Built from high-speed steel with an oxide finish, it carries a 3 Morse taper shank for secure seating in compatible drill press spindles, lathes, and milling machine quills. The 118-degree standard point angle is suited to general-purpose drilling across a wide range of workpiece materials. With a flute length of 5.875 inches and an overall length of 10.5 inches, the bit provides the reach and chip-clearance depth needed for production and maintenance drilling applications. Web thinning reduces thrust load and improves penetration at the point.\u003c\/p\u003e\u003cp\u003eThis drill bit is a general-purpose cutting tool used in machine shops, maintenance and repair operations, and production environments. The 3MT shank interfaces directly with any machine spindle or drill chuck sleeve rated for Morse taper No. 3, making it a common selection for drill presses and engine lathes. Right-hand spiral flutes eject chips efficiently during through-hole and blind-hole operations. It is appropriate for use by machinists, toolmakers, and industrial maintenance technicians working on metal fabrication and repair tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch diameter with a diameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003eNo. 3 Morse taper shank for positive drive and self-holding fit in compatible machine spindles\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose drilling in a broad range of materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance and lubricity\u003c\/li\u003e\n\u003cli\u003eWeb-thinned point reduces required thrust force and improves cut initiation\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flutes provide effective chip evacuation in through and blind holes\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M standards; Series 2412\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any machine spindle, drill press, or lathe tailstock equipped with a No. 3 Morse taper socket.

Before inserting the bit, ensure the spindle bore and taper shank are clean and free of chips or oil to allow full seating and prevent slippage under load. Power down and lock out the machine before installing or removing the bit. Use a drift key and mallet against the spindle drift slot to remove the bit safely — never attempt to pull the shank free by hand under power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 3MT (Morse Taper No. 3)\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\u003eFlute Length\u003c\/strong\u003e: 5.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.5 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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2412\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: C12678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693583106354,"sku":"C12678","price":163.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edbdae676af85de54df2a5cd89a5ea72.jpg?v=1788314425","url":"https:\/\/voomisupply.com\/products\/cleveland-c12678-taper-shank-drill-bit-3-4-in-3mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
