It features a 1\/2 inch cutting diameter, a 2-1\/2 inch length of cut, and a 4-1\/2 inch overall length. The four-flute, right-hand helical geometry with a 38-degree helix angle promotes efficient chip evacuation and stable cutting. An AlTiN-based coating designated WP15PE provides thermal resistance and extends tool life in high-heat applications. This end mill is single-ended and is installed and operated by machinists and CNC machine operators working in job shops, tool rooms, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for cutting steel, stainless steel, superalloys, titanium, hard materials, and high-temperature alloys. It is a right-hand cut tool suited for use in vertical and horizontal milling machines and CNC machining centers. The 1\/2 inch Weldon Flat shank provides positive drive and reduces pullout risk under heavy cutting loads. The regular-length geometry makes it well suited for standard-depth cavity milling, slotting, and peripheral milling operations across a range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eWP15PE AlTiN-based coating for elevated heat and oxidation resistance\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eFour flutes for balance between material removal rate and chip clearance\u003c\/li\u003e\n\u003cli\u003eWeldon Flat shank for secure, positive drive with minimal pullout\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing direct plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2 inch collet chucks, Weldon-style end mill holders, and side-lock holders compatible with a 1\/2 inch shank diameter.

Secure the Weldon Flat shank fully into a compatible end mill holder before tightening the set screw. Ensure the machine spindle is fully stopped and locked out before changing or measuring the tool. Confirm runout with a dial indicator after installation before beginning a cut, as excessive runout will accelerate wear and reduce surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WP15PE (AlTiN-based)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: High Temperature Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4V05\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.39 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WIDIA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5576623\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67911261815090,"sku":"5576623","price":270.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ecaeb85bb7e0ca02544923b91abd8c1_ce7c8fdd-6ad8-4a20-a582-9e1a5f723b37.jpg?v=1791208109","url":"https:\/\/voomisupply.com\/products\/widia-5576623-square-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
