Built from M42 cobalt high-speed steel, it delivers heat and wear resistance in applications where standard HSS bits fall short. The 135-degree split point reduces walking and lowers thrust requirements at entry, making it well suited for hard alloys and interrupted cuts. Overall length is 3.25 inches, with a 1.875-inch flute length, giving it a compact, rigid profile that minimizes deflection in short-stroke drilling operations. Licensed tradespeople and machining professionals install this bit in drill presses, CNC machining centers, and manual screw machines.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for drilling alloy steel, aluminum, and similarly demanding workpiece materials. The screw machine length format is a standard choice in production environments where rigidity matters more than reach. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup during continuous drilling cycles. It meets ASME B94.11M and ANSI specification designation standards, making it appropriate for controlled-tolerance work in shop and field settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and minimizes bit walking\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast, efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0010 inches for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard supply drill bit for use in screw machines, drill presses, and CNC machining centers requiring a straight-cylindrical shank bit in the 0.3500 to 0.4000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and tool-and-die professionals in machine shop environments. Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation and verify chuck key is removed before powering the spindle. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drill presses or CNC equipment. Do not exceed the recommended feed and speed ratings for the workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inches (0.3906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches (82.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (33.34 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3906 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\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2175\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 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: C14221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695549481266,"sku":"C14221","price":43.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/add08a82740fa373bb351d6987563a9f.jpg?v=1788336342","url":"https:\/\/voomisupply.com\/products\/cleveland-c14221-screw-machine-drill-bit-25-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
