Built from M42 cobalt steel, this bit handles alloy steels, aluminum, and other tough materials where standard high-speed steel bits fall short. It features a 135-degree split point for fast starts without center-punching and a parabolic flute geometry that clears chips efficiently. The straight cylindrical shank measures 0.2010 inches in diameter, matching the wire size 7 designation at 0.2010 inches drill diameter. At 2.25 inches overall length, the stub-style body is rigid and reduces deflection during tight-clearance or fixture-guided drilling operations.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machinists, tool-and-die workers, sheet metal fabricators, and maintenance technicians who need a compact, high-duty drill for production or repair work. The screw machine length format fits drill presses, CNC machining centers, hand drills, and right-angle drill setups where a jobber-length bit would be too long. Primary workpiece materials include alloy steel and aluminum. The web-thinned, parallel web configuration reduces thrust load at the cutting edge, which is useful when drilling through harder alloy grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and extended tool life in alloy and hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact, no center-punch required\u003c\/li\u003e\n\u003cli\u003eParabolic flute design improves chip evacuation in deep or interrupted cuts\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2.25 inches OAL reduces deflection and fits tight setups\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers drilling thrust and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0007 inches for close-tolerance holes per ASME B94.11M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty OEM-style screw machine drill bit for use in standard straight-shank drill chucks across drill presses, CNC machines, and hand-held power drills.

Secure the shank fully in the chuck before operation and verify runout is within tolerance for close-fit hole applications. Use appropriate cutting fluid or coolant for the workpiece material, as this bit does not support coolant-through capability. Inspect the cutting edges and point for wear or chipping before each use, and replace the bit when diameter tolerance can no longer be held.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: M42 Cobalt Steel\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\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2010 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 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: 2175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: C14247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51705314378034,"sku":"C14247","price":23.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa77943d95a6af6b1d32de2b5ea4eb96.jpg?v=1788428172","url":"https:\/\/voomisupply.com\/products\/cleveland-c14247-screw-machine-drill-bit-size-7-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
