Built to Series 2133 standards, this bit features a 7.4 mm (0.2913 inch) diameter, a 135-degree split point for fast, accurate starts with minimal walking, and a web-thinned construction that reduces thrust and improves chip evacuation. The heavy-duty M42 cobalt material grade delivers heat resistance and edge retention when cutting through tough workpiece materials. It is sold individually and suited for use by machinists, maintenance technicians, and metalworking professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in alloy steels and aluminum, making it a practical choice for fabrication shops, maintenance and repair operations, and production environments where shorter overall length provides better rigidity in confined setups. The screw machine length profile is shorter than jobber-length bits, reducing deflection and increasing precision in drill press, CNC, and hand-held power tool applications. The straight-cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt material grade for heat resistance and extended tool life in hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and lowers required entry thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web construction improves chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eScrew machine length (74 mm OAL) provides increased rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral fluting for standard drilling operations\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 1897 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for applications requiring a 7.4 mm diameter hole in alloy steel or aluminum workpieces, compatible with any standard drill chuck accepting a 0.2913-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with metalworking safety practices. Always secure the workpiece before drilling and set spindle speed appropriate to the workpiece material and bit diameter. Inspect the cutting edges before each use and replace if chipping or excessive wear is present. No coolant-through capability is available on this bit, so apply cutting fluid externally when drilling harder alloys to manage heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.4 mm (0.2913 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm (2.9134 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm (1.5748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2913 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 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\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\u003eWeight\u003c\/strong\u003e: 0.35 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: C14811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51701094023474,"sku":"C14811","price":18.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52d63f7d6ed7ecf25d68f4da4b7ff374.jpg?v=1788398150","url":"https:\/\/voomisupply.com\/products\/cleveland-c14811-screw-machine-drill-bit-7-4mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
