Built from M42 cobalt high-speed steel with a bright uncoated finish, it handles tough ferrous and non-ferrous materials where heat resistance and edge toughness matter. The 1\/2 inch diameter, 4-flute configuration with a 30-degree helix angle provides a balance of chip evacuation and surface finish. A Weldon flat shank ensures positive drive and minimal slippage in the holder. This tool is installed and used by machinists and tool-and-die professionals on vertical and horizontal milling machines and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing and finishing operations on steel, stainless steel, cast iron, and similar materials in both job-shop and production environments. The 3 inch length of cut accommodates deeper pocketing and slotting applications where standard-length end mills fall short. The right-hand flute direction and right-hand cutting configuration are standard for conventional CNC and manual milling setups. With a 1\/2 inch shank diameter matching the cutter diameter, it seats directly in standard ER, set-screw, or Weldon-style tool holders without a reducer sleeve.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for superior heat and wear resistance compared to standard M2 tools\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree helix geometry balances chip removal with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e3 inch length of cut supports deep pocket, slot, and peripheral milling operations\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and prevents tool pullout under load\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish is suitable for regrinding and re-coating after wear\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with square end profile for flat-bottom features and shoulder milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct fit for standard 1\/2 inch Weldon flat and set-screw tool holders used on CNC machining centers, knee mills, and manual vertical mills.

Ensure the spindle is fully stopped and the machine is powered down before loading or removing the end mill from the holder. Torque set screws to the tool holder specification using calibrated tooling — do not overtighten against the Weldon flat. This tool is not center-cutting; plunge milling is not recommended.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 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: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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\u003eCentercutting\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 724-4128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696856924466,"sku":"724-4128","price":160.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5dac54aba23ac644ce2ed7a7ed28486.jpg?v=1788347092","url":"https:\/\/voomisupply.com\/products\/value-collection-724-4128-roughing-finishing-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
