Built from M42 cobalt high-speed steel with a coated finish, it carries a No. 31 wire gauge diameter of 0.1200 inches and an overall length of 1.875 inches. The 135-degree split point reduces thrust force and self-centers on entry, minimizing the need for a center punch on most surfaces. Two spiral flutes with a web-thinned, parallel web configuration promote chip evacuation and reduce heat buildup during continuous use. This bit is sold individually and must be ordered in multiples of 10.\u003c\/p\u003e\n\u003cp\u003eThe C14570 is suited for drilling alloy steels and aluminum in high-cycle production environments, machine shops, and fabrication settings. Its screw machine length — shorter than jobber length — provides added rigidity and reduces deflection when used in drill presses, CNC machining centers, turret lathes, and hand-held power tools where stub-length bits are specified. The straight cylindrical shank fits standard drill chucks without modification. Right-hand cutting direction is standard for conventional drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat and wear resistance in tough alloy and aluminum drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for reduced entry thrust and self-centering performance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1.875 inches OAL for increased rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with parallel web configuration for efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for consistent, precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 1897 standards; ANSI and DIN designated\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks accepting a 0.1200-inch straight cylindrical shank.

Ensure the drill chuck is fully tightened and the bit is seated squarely before operation. Use appropriate cutting fluid or coolant for the workpiece material when drilling alloy steels to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is degraded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1200 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\u003eTool Material\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1200 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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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: C14570\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51712288129330,"sku":"C14570","price":60.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bb1ed657ed77f717a31aeb619bef76d.jpg?v=1788485944","url":"https:\/\/voomisupply.com\/products\/cleveland-c14570-screw-machine-drill-bit-no-31-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
