Built from M42 cobalt high-speed steel, it delivers higher heat resistance and edge retention than standard HSS tooling. The short overall length of 1-3\/8 inches reduces deflection and improves rigidity in tight-clearance drilling operations. It is designed for right-hand cutting with a straight cylindrical shank and two spiral flutes. Machinists, tool and die workers, and maintenance technicians use this bit for small-diameter hole production in production drilling applications.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling alloy steels and aluminum in screw machine, CNC, and benchtop drill press operations. The short screw machine length provides added rigidity compared to jobber-length bits, making it well-suited for cross-drilling, tapping prep, and precision work where hole location accuracy and minimal walkout are priorities. The split point geometry starts on contact without a center punch on most materials, reducing setup steps in high-volume operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat resistance in tough alloy and aluminum drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for self-starting entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 1-3\/8 inches overall for maximum rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and DIN 1897 specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-compatible replacement or standard production drill bit for use in any straight-shank drill chuck accepting a 0.0465-inch diameter bit; primary workpiece materials listed as alloy steel and aluminum.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by a qualified machinist or trained tradesperson familiar with drill press or machine tool operation. Secure the shank fully in the chuck and verify runout before drilling. Ensure the workpiece is clamped or fixtured to prevent movement during the cut. Use appropriate cutting fluid for alloy steel applications to extend tool life and maintain hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0465 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0465 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt HSS (M42)\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 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\u003eSeries\u003c\/strong\u003e: 2133\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\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: C14508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690386260274,"sku":"C14508","price":57.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55527680ba0a4ed0e1cc3a0f51e5bb65.jpg?v=1788269755","url":"https:\/\/voomisupply.com\/products\/cleveland-c14508-no-56-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
