Built to M42 cobalt material grade, this double-end, center-cutting tool features a 0.25-inch mill diameter, a 0.5-inch length of cut, and a 3\/8-inch straight-cylindrical or Weldon flat shank. The 30-degree spiral flute geometry promotes efficient chip evacuation and heat resistance, making it well-suited for production environments where tool longevity under load is a priority. Licensed machinists and tool-and-die professionals install this end mill in CNC and manual milling machines where consistent edge geometry is critical.\u003c\/p\u003e\u003cp\u003eThe C52155 is rated for use on high-temperature alloys, stainless steel, and carbon and alloy steels. Its regular-length classification and 3-3\/8-inch overall length make it a standard choice for pocketing, slotting, and peripheral milling operations in job shops, aerospace component shops, and general metalworking facilities. The right-hand cut and right-hand flute configuration is the standard orientation for conventional milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS tooling\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge milling in addition to peripheral and slot cuts\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eDouble-end configuration provides two usable cutting ends, extending tool service life\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical or Weldon flat shank accommodates a wide range of collet and end mill holder types\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids on ferrous and high-temp alloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on high-temperature alloys, stainless steel, and steel workpieces; fits standard 3\/8-inch end mill holders, collets, and Weldon-style chucks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following shop-standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the holder and torque set screws to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical \/ Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HDC-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, Steel\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: C52155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698136514866,"sku":"C52155","price":54.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccd40e705aa39e953455bdf0ce8d9238.jpg?v=1788358297","url":"https:\/\/voomisupply.com\/products\/cleveland-c52155-square-end-mill-0-25-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
