Built from high-speed steel with an oxide finish, it features a 1-inch diameter, a 4 Morse taper shank for secure spindle engagement, and a 118-degree standard point angle with web thinning for easier penetration at startup. The right-hand spiral flute configuration and regular helix promote efficient chip evacuation during deep-hole drilling. This bit conforms to ASME B94.11M standards, confirming dimensional consistency for professional use.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general-purpose drilling in ferrous and non-ferrous metals, including mild steel, cast iron, and aluminum. The 4 Morse taper shank seats directly in drill press spindles, milling machine quills, or lathe tailstocks equipped with a 4MT socket. With a 6.375-inch flute length and 12-inch overall length, it handles deep-hole operations that shorter jobber-length bits cannot reach. Machinists, millwrights, and maintenance technicians working with large-bore through-holes will find this length-to-diameter ratio practical for production and repair work alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch diameter with a tight tolerance of +0.0000 to -0.0012 inches for accurate hole sizing\u003c\/li\u003e\n  \u003cli\u003e4 Morse taper shank for direct mounting in compatible spindles without a chuck\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced thrust at entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for heat resistance in general-purpose cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in machine tool spindles, drill presses, milling machines, and lathe tailstocks equipped with a 4 Morse taper socket.

Clean and inspect the taper socket and shank for burrs or debris before seating to ensure full contact and prevent slippage under load. Secure the bit using a drawbar or drift as appropriate for the machine design. Verify workpiece is clamped and machine is at the correct speed for the material and diameter before beginning the cut.\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 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.375 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 Helix\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 -0.0012 inches\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  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: C12684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51705625215282,"sku":"C12684","price":241.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edbdae676af85de54df2a5cd89a5ea72_78358f66-b12c-4bba-bde2-775cfba673eb.jpg?v=1788430063","url":"https:\/\/voomisupply.com\/products\/cleveland-c12684-taper-shank-drill-bit-1-in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
