At 1\/2 inch in diameter with a 135-degree split point and web-thinned tip, it starts fast and cuts cleanly without walking. The M42 cobalt construction handles the heat generated in alloy steel and aluminum applications where standard HSS bits fail prematurely. Built to Series 2133 specs, this is a production-grade tool suited for machine shop use, maintenance drilling, and fabrication work. Licensed machinists, millwrights, pipefitters, and industrial mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe C14731 is built for drilling alloy steels and aluminum in screw machine, drill press, and CNC setup applications. The shorter overall length of 3.75 inches improves rigidity and reduces deflection in tight workpiece clearances. The straight cylindrical shank seats securely in standard 1\/2 inch chucks. Two-flute spiral construction promotes chip evacuation during through-hole and blind-hole operations. This bit is well suited to production environments where consistent hole tolerance and tool life matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for extended tool life in alloy and aluminum drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (3.75 inches OAL) provides rigidity and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral and 2-flute configuration for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 1\/2 inch drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 1897 dimensional standards\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 drill bit compatible with standard 1\/2 inch straight-shank drill chucks on drill presses, CNC machining centers, and screw machines.

Ensure the workpiece is clamped and the spindle speed is set appropriately for the material and bit diameter before starting. Cutting fluid or coolant is recommended for alloy steel drilling to extend tool life, even though this bit does not feature through-coolant capability. Inspect the cutting edges before each use and replace if chipping or dullness is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches (3-3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 inches (2-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 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\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\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eSeries\u003c\/strong\u003e: 2133\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\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\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 1897 (ANSI\/DIN)\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: C14731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51718278480178,"sku":"C14731","price":35.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b053e1c7dd7d8ff8c45d51c0e0275200.jpg?v=1788551525","url":"https:\/\/voomisupply.com\/products\/cleveland-c14731-1-2-in-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
