Built from M42 cobalt high-speed steel, this double-end, two-flute tool measures 0.3438 inches (11\/32 inches) in cutting diameter with a 0.5625-inch (9\/16 inches) length of cut and a 3.5-inch overall length. The spiral flute geometry and 30-degree helix angle promote chip evacuation and reduce cutting forces. The centercutting design allows plunge milling in addition to peripheral and slot milling. Licensed machinists and tool-and-die professionals reach for this series when working materials that demand heat-resistant tooling.\u003c\/p\u003e\u003cp\u003eThe C52158 is suited for milling stainless steel, high-temperature alloys, and general steel workpieces where cobalt tooling outperforms standard high-speed steel. Its HDC-2 series designation places it in a heavy-duty category built for rigidity and longer tool life in these tough materials. The 3\/8-inch straight-cylindrical shank with Weldon flat is compatible with standard end mill holders and set-screw style tool holders on vertical mills, CNC machining centers, and knee mills running right-hand spindle rotation.\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\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables plunge, slot, and peripheral milling\u003c\/li\u003e\n\u003cli\u003eDouble-end design extends usable tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eWeldon flat on 3\/8-inch shank for positive grip in set-screw holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/8-inch end mill holders and Weldon-style tool holders.

Ensure the spindle is fully stopped and the machine is in a locked-out state before changing tooling. Seat the Weldon flat against the set screw in the tool holder and torque to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut to maximize tool life and surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 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 with Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HDC-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: C52158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700401242418,"sku":"C52158","price":58.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aac2a2891f8effe9c5fe24a9047df496.jpg?v=1788389886","url":"https:\/\/voomisupply.com\/products\/cleveland-c52158-square-end-mill-11-32-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
