Built to an overall length of 3.11 inches with a flute length of 1.457 inches, this bit delivers the rigidity needed for accurate hole placement without deflection. The 135-degree split point starts on contact without center-punching, reducing walking on hard materials. Constructed from M42 cobalt high-speed steel, the C14812 handles elevated heat generated when cutting alloy steels and aluminum without losing edge hardness. It is a heavy-duty grade tool suited for machinists, maintenance technicians, and fabricators who need consistent results in production or repair environments.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits are the go-to choice when stub rigidity is required in drill presses, CNC machining centers, lathes, and hand-held power drills working in tight clearances. The C14812 is rated for alloy steel and aluminum as primary workpiece materials, making it appropriate for HVAC bracket fabrication, structural steel maintenance, and general metalworking tasks. The straight cylindrical shank with a diameter of 0.315 inches seats securely in standard three-jaw chucks and collet systems without requiring a specialized holder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction resists heat buildup during high-speed cutting in alloy and aluminum stock\u003c\/li\u003e\n  \u003cli\u003e135-degree split point initiates cutting on contact, eliminating center-punch prep on most metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web geometry reduces thrust load and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides added rigidity compared to jobber-length bits, reducing deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with regular helix promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 1897 standards for dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0010 inches ensures precise, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit for standard three-jaw chucks and collet holders accepting a 0.315-inch straight cylindrical shank, compatible with drill presses, CNC machining centers, lathes, and hand-held power drills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and maintenance technicians using standard drill press, lathe, or hand-held drill equipment. Secure the shank fully in the chuck or collet before operation and verify runout before drilling into workpiece material. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling alloy steel to extend edge life. Always wear appropriate eye protection and follow applicable shop safety protocols when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.457 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.654 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eSeries\u003c\/strong\u003e: 2133\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, ANSI, DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\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: C14812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51702567436594,"sku":"C14812","price":19.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/656b0769500aee95bfb5b7d67df7d4d2.jpg?v=1788412017","url":"https:\/\/voomisupply.com\/products\/cleveland-c14812-cobalt-screw-machine-drill-bit-0-315-in","provider":"Voomi Supply","version":"1.0","type":"link"}
