Built from M42 cobalt high-speed steel, it handles tough ferrous alloys and hardened materials that standard HSS tooling cannot efficiently cut. The 1\/4 inch cutting diameter and 30-degree helix angle promote smooth chip evacuation and reduced cutting forces. The bright uncoated finish suits applications where coating adhesion or heat buildup is not a concern. Licensed machinists and tool-and-die professionals use this style of end mill for profiling, slotting, and ramping cuts on vertical mills and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations in job shops, maintenance facilities, and production environments working with steel, stainless steel, and similar ferrous materials. The Weldon flat shank provides a positive mechanical lock in end mill holders and reduces tool pullout under high feed loads. Its single-end configuration and square end geometry make it a direct fit for standard milling chucks and collet holders accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat resistance in hard and tough materials\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip clearance and surface finish capability\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank prevents tool pullout in side-lock holders\u003c\/li\u003e\n\u003cli\u003eSquare end geometry supports profiling, slotting, and shoulder milling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for general-purpose milling without coating concerns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders, Weldon-style side-lock holders, and collet chucks accepting a 3\/8 inch shank diameter on vertical knee mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the Weldon flat against the side-lock set screw to the manufacturer-specified engagement depth to prevent pullout under load. Verify runout with a dial indicator before beginning cuts when tight tolerances are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 724-4023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692514181426,"sku":"724-4023","price":55.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4555bad759d1a8ec17639aab2559bb7b.jpg?v=1788298697","url":"https:\/\/voomisupply.com\/products\/value-collection-724-4023-end-mill-1-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
