Designed for heavy-duty drilling applications, it features a 135-degree split point that reduces walking and cutting force at entry, and a web-thinned parallel web for improved chip evacuation. With an overall length of 2.375 inches and a straight-cylindrical shank, this bit is built for use in screw machine and production drilling environments where compact tooling is required. Machinists, toolroom technicians, and production operators are the primary installers and users of this tooling.\u003c\/p\u003e\u003cp\u003eThe C70309 is suited for drilling into alloy steels and aluminum in production or job-shop settings. Its screw machine length body reduces deflection and improves rigidity in short-reach applications such as turret lathes, CNC screw machines, and drill presses where stub-length tooling is preferred. The right-hand cut, regular spiral flute geometry handles a broad range of metal drilling tasks at standard feed and speed conditions appropriate for high-speed steel tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size No. 5 with 0.2055-inch decimal diameter and tight tolerance of +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates center-punch requirement on most metals\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web construction improves chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for heavy-duty service across alloy steel and aluminum workpieces\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body at 2.375 inches OAL improves rigidity in short-reach setups\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and NAS 907 Type C standards for dimensional and performance conformance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit suitable for use in standard straight-shank drill chucks and collet holders sized for 0.2055-inch shank diameter tooling in production and general machining applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or toolroom personnel familiar with cutting tool setup and speeds-and-feeds selection for high-speed steel tooling. Ensure the machine spindle and chuck or collet are fully de-energized and locked out before loading or changing tooling. Verify chuck or collet bore is clean and within tolerance for a 0.2055-inch straight shank before seating the bit. Do not exceed recommended surface footage for high-speed steel when drilling alloy steel or aluminum to avoid premature edge breakdown.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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 Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\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: C70309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699460964658,"sku":"C70309","price":58.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_835aa5fb-c8c7-4c5e-8fe2-0cec8f6e0b92.jpg?v=1788375896","url":"https:\/\/voomisupply.com\/products\/cleveland-c70309-no-5-hss-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
