Built to Series 2330 standards, this wire-gauge No. 7 bit measures 0.2010 inches in diameter with an overall length of 2.25 inches, making it well suited for stub-length drilling where rigidity and minimal deflection are priorities. The 135-degree split point reduces thrust and self-centers on contact, eliminating the need for a center punch in most setups. Web thinning further reduces cutting resistance. Licensed machinists, tool-and-die workers, and maintenance technicians install this bit in benchtop drill presses, CNC machining centers, and handheld drilling tools.\u003c\/p\u003e\n\u003cp\u003eThe C70311 is suited for drilling alloy steel and aluminum workpieces in production and maintenance environments. Its screw machine length profile — shorter than a jobber bit — delivers increased rigidity in applications where hole location accuracy and surface finish matter, such as tapping prep, close-tolerance assembly drilling, and sheet metal work. The bright uncoated finish makes it a practical general-purpose choice where a coating is not required by the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size No. 7 diameter: 0.2010 inches with a tolerance of +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering and reduced drilling thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web for lower cutting resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (2.25 inches OAL) for enhanced rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for alloy steel and aluminum workpieces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish; no additional heat treatment or coating to affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and NAS 907 Type C specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw machine length replacement or production drill bit for use with standard 3-jaw drill chucks accepting a 0.2010-inch straight cylindrical shank.

Secure the shank fully into the chuck and verify concentricity before operation. Ensure the workpiece is clamped securely to prevent movement during drilling. Inspect the cutting edges and point geometry before each use and replace the bit if chipping or dulling is observed.\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. 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2010 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\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\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, NAS 907 Type C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: C70311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720761311538,"sku":"C70311","price":50.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_c3e7ca4f-e541-4ec8-b8c2-da7d93356ab9.jpg?v=1788568761","url":"https:\/\/voomisupply.com\/products\/cleveland-c70311-screw-machine-drill-bit-wire-size-7-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
