Built from M42 high-performance cobalt steel, it delivers the heat and wear resistance needed for demanding drilling applications. The parabolic flute geometry promotes efficient chip evacuation and reduces cutting pressure. With an overall length of 4.125 inches and a flute length of 2.875 inches, this bit is well suited to general-purpose drilling in both production shop and field environments. Licensed tradespeople and machinists handling hard or abrasive materials are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for right-hand drilling in cast iron, non-ferrous metals, stainless steel, and carbon or alloy steel. The web-thinned, tapered web design reduces entry resistance in harder workpieces, making it a practical choice for metalworking shops, maintenance machinists, and fabrication tradespeople working with ferrous and non-ferrous stock. It follows a straight-cylindrical shank profile that seats directly into standard drill chucks without requiring a collet adapter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for high heat and wear resistance during hard-material drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for fast engagement and reduced walking on entry\u003c\/li\u003e\n\u003cli\u003eTiN coating extends cutting edge life in abrasive and ferrous materials\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes rapid chip clearing and lower thrust requirements\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 338 standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for applications requiring a Letter F (0.2570-inch) jobber drill in cast iron, non-ferrous metals, stainless steel, and steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or qualified maintenance tradespeople using a standard drill press, milling machine, or hand drill with a keyed or keyless chuck. Ensure the chuck is fully tightened and the shank is fully seated before operation. Use appropriate cutting fluid or coolant where required by the workpiece material to maximize tool life, noting that this bit does not have through-coolant capability. Follow applicable shop safety standards and wear eye protection during all drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2570 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches (104.78 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches (73.03 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2570 inches (6.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.250 inches (31.75 mm)\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\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eMaterial\u003c\/strong\u003e: Cobalt Steel, Grade M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Gold)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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 Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.004 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: C15654\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51704864899378,"sku":"C15654","price":29.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f17a95740d972c69b0b9fa89d8b48f0_1f30b46a-4f84-4c7b-8421-39a04c136781.jpg?v=1788425449","url":"https:\/\/voomisupply.com\/products\/cleveland-c15654-cobalt-jobber-drill-bit-letter-f","provider":"Voomi Supply","version":"1.0","type":"link"}
