Built from high-speed steel with an oxide finish, it resists heat and wear during extended use. The bit features a 118-degree standard point angle with web thinning to reduce thrust and improve hole entry. At 11\/32 inches (0.3438 inches) in diameter, it fits a No. 1 Morse Taper (1MT) spindle and delivers consistent results in drill press and machine tool setups. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this style of bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production and maintenance environments where a taper shank interface is required for secure, self-locking tool holding. The 3-1\/4-inch flute length provides adequate chip clearance for moderate-depth holes, and the 6-1\/2-inch overall length accommodates standard 1MT spindle sockets on bench drill presses, radial arm drills, and similar machinery. It is a right-hand cutting, regular spiral design built for general-purpose work in both job shop and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced drilling thrust\u003c\/li\u003e\n  \u003cli\u003eNo. 1 Morse Taper shank for self-locking fit in compatible spindles\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0010 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any machine tool or drill press equipped with a No. 1 Morse Taper (1MT) spindle socket.

Power down and lock out the machine before inserting or removing the taper shank. Clean both the shank and the spindle socket before seating to ensure full contact and prevent slippage. Use a drill drift and mallet to eject the bit safely — never strike the spindle housing directly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/2 inches (6.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/4 inches (3.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper\u003c\/strong\u003e: 1MT (No. 1 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Treatment\u003c\/strong\u003e: Web-Thinned\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 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: C12139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695846687026,"sku":"C12139","price":59.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dbf11dfd75702b5ecc2df24a5258add_d280ab07-ced2-4ae3-84f7-c89149e16e5b.jpg?v=1788338742","url":"https:\/\/voomisupply.com\/products\/cleveland-c12139-taper-shank-drill-bit-11-32-in-1mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
