Built from M42 cobalt high-speed steel, it holds up under the heat generated by hard and abrasive materials where standard HSS bits fail. The bit measures 0.25 inches in diameter (Letter E) with an overall length of 2.5 inches, making it suited for short-reach, rigid setups in drill presses, CNC machines, and hand-held equipment. The 135-degree split point starts on contact without a center punch, reducing walking and improving hole accuracy.\u003c\/p\u003e\u003cp\u003eThis bit is intended for production and maintenance environments where consistent hole quality in tough materials is required. Primary workpiece materials include alloy steel and aluminum. The screw machine length body keeps the bit compact and stiff, reducing deflection in close-tolerance work. It is commonly used by machinists, tool-and-die workers, and maintenance technicians working in industrial and commercial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat resistance in alloy steel and aluminum drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact, no center punch required\u003c\/li\u003e\n\u003cli\u003eWeb-thinned design reduces thrust force and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine length body minimizes deflection in rigid setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2-flute regular spiral for standard chip flow\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 1897 standards for consistent dimensional quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use bit for drill presses, CNC drilling operations, and hand-held equipment requiring a 0.25-inch straight-cylindrical shank screw machine length drill bit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with drill press and rotating tool safety procedures. Secure the straight-cylindrical shank firmly in the chuck before operation and verify runout before production drilling. Always power down and de-energize the machine before changing bits. Use appropriate cutting fluid for the workpiece material to extend bit life and maintain hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 0.25 inches (Letter E, 1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 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: 0.25 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\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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: C14646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51712756744498,"sku":"C14646","price":15.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/196597029bc92cc46b20dea61fcaf939.jpg?v=1788488397","url":"https:\/\/voomisupply.com\/products\/cleveland-c14646-screw-machine-drill-bit-letter-e-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
