Built from M42 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard HSS bits. The 135-degree split point reduces walking at entry and requires less thrust to initiate a hole. At 1-3\/8 inches overall length, the shortened screw machine geometry provides added rigidity in tight-clearance applications. Two spiral flutes evacuate chips efficiently, and the web-thinned, parallel-web construction keeps cutting forces manageable across extended run cycles. This bit suits machinists, maintenance technicians, and fabricators working with CNC machines, drill presses, and handheld power tools.\u003c\/p\u003e\n\u003cp\u003eThe C14504 is sized at No. 58 wire gauge, equal to 0.0420 inch decimal diameter. The screw machine length format makes it well suited for short, rigid setups where a jobber-length bit would flex or chatter. Typical applications include production drilling in alloy steels and aluminum in both shop and field environments. The straight-cylindrical shank is compatible with standard three-jaw chucks and collet holders sized for 0.0420 inch shank stock. Right-hand cut geometry is standard for conventional drilling operations. The bit conforms to ASME B94.11M and DIN 1897 dimensional standards, making it a direct fit in metric and inch tooling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat resistance in alloy and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers required entry thrust\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (1-3\/8 inches OAL) provides rigidity in confined setups\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces cutting resistance and extends tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand, two-flute spiral design promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M and DIN 1897 for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard three-jaw chucks and collet systems accepting a 0.0420 inch straight-cylindrical shank.

Ensure the spindle speed and feed rate are appropriate for the workpiece material and bit diameter — consult published speeds-and-feeds charts for cobalt HSS tooling. No coolant-through capability is present on this bit; apply cutting fluid externally when drilling alloy steel or other work-hardening materials. Inspect the split point for chipping or wear before each use, as a damaged point will produce oversized or off-location holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 58\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0420 inches\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\u003eOverall Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.8750 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0420 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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 -0.0005 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\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\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: C14504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722349314354,"sku":"C14504","price":61.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47030faf7dbcc0c8352c49a21949413a.jpg?v=1788589819","url":"https:\/\/voomisupply.com\/products\/cleveland-c14504-screw-machine-drill-bit-no-58-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
