Built from M42 cobalt high-speed steel, this double-end mill features a 3\/8-inch cutting diameter, a 9\/16-inch length of cut, and a 3-1\/2-inch overall length. The spiral flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. With centercutting capability, the C52159 can plunge directly into the workpiece, expanding its versatility on the milling machine or machining center. This tool is uncoated and intended for right-hand cut and right-hand flute orientation.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling high-temperature alloys, stainless steel, and general steel stock in job shop, maintenance, and production environments. The HDC-2 series designation indicates a heavy-duty cobalt construction appropriate for tougher workpiece materials where standard HSS tooling wears prematurely. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw tool holders with a 3\/8-inch bore. It is a regular-length tool appropriate for general-purpose side milling, slotting, and plunge operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for extended tool life in hard-to-machine materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends, extending service life\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eStraight shank with Weldon flat for secure clamping in set-screw holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for standard 3\/8-inch end mill holders and Weldon-style tool holders used in vertical milling machines and machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Secure the Weldon flat shank fully into a matching 3\/8-inch tool holder and tighten the set screw against the flat to prevent tool pull-out under load. Verify spindle direction is set to right-hand rotation before engaging the cut. Inspect both cutting ends for damage before use and follow shop-standard feeds and speeds for cobalt tooling in the selected workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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 (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble End\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\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: C52159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51701158936882,"sku":"C52159","price":61.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f230032de609f29e7a378870b82979c5.jpg?v=1788399020","url":"https:\/\/voomisupply.com\/products\/cleveland-c52159-square-end-mill-3-8-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
