Built to Series 2330 standards, this bit features a 135-degree split point and web-thinned geometry that reduces walking and lowers thrust on entry. At 21\/64 inch (0.3281 inch) in diameter and 2-15\/16 inches overall length, it fits stub-reach drilling setups where a jobber-length bit would interfere with the workpiece or fixturing. The straight-cylindrical shank accommodates standard drill chucks and collets. Right-hand cut with a regular spiral and two flutes. Intended for installation and service use by machinists, HVAC fabricators, plumbers, and electricians working in metal fabrication or equipment assembly.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling into alloy steel and aluminum in production and field service environments. The screw machine length body keeps the cutting edge close to the chuck, improving rigidity and reducing deflection in short-hole work. Typical applications include drilling through sheet metal, structural steel, enclosure panels, and fittings where hole location accuracy and clean entry are required. The bright uncoated finish makes it appropriate for use with cutting fluids or dry in lower-speed setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch marking on most metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web construction lowers cutting resistance during penetration\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2-15\/16 inches OAL increases rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for heavy-duty grade service\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.3281 inch diameter fits standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and NAS 907 Type C specifications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit screw machine length drill bit for standard drill chucks, collets, and drill presses accepting a straight-cylindrical shank in the 21\/64 inch diameter range.

Secure the shank fully seated in the chuck before operation. Use appropriate cutting fluid when drilling alloy steel to extend tool life and maintain hole tolerance. Handle uncoated HSS bits carefully — edge chipping from improper storage or contact with hardened surfaces will reduce performance on first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/64 inch (0.3281 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3281 inch\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 -0.0010 inch\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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: 0.3 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: C70268\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715326968114,"sku":"C70268","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_33e087c0-40f5-4f14-b018-8cce2bacf556.jpg?v=1788512113","url":"https:\/\/voomisupply.com\/products\/cleveland-c70268-21-64-in-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
