Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed for cutting steel, stainless, and other tough alloys. The 3\/4 inch diameter, 4-flute geometry with a 30-degree helix angle balances chip evacuation with surface finish quality. At 2.5 inches length of cut and 4.625 inches overall length, this tool suits deep-slot and peripheral milling operations on manual mills and CNC machining centers alike. The Weldon flat shank provides positive drive retention in standard end mill holders.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for job shops, tool rooms, and production environments handling ferrous metals and high-nickel alloys where standard HSS tooling falls short. The right-hand cut, right-hand flute configuration is the standard orientation for conventional milling setups. Single-end construction makes it a straightforward replacement when one cutting end is worn. The bright uncoated finish means it can be resharpened without stripping a coating layer, keeping regrind costs low.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt material grade for elevated heat resistance versus standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances chip flow and radial cutting forces\u003c\/li\u003e\n\u003cli\u003e4-flute square end geometry supports both roughing and finishing passes\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank ensures positive engagement in end mill holders and reduces pullout risk\u003c\/li\u003e\n\u003cli\u003eBright uncoated surface is regrind-friendly without coating removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling orientation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 3\/4 inch end mill holders and collet chucks used in manual knee mills and CNC vertical machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to prevent axial pullout. Verify runout with a dial indicator before beginning a cut, particularly for finishing passes where tolerance is critical.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 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\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 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\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: 724-4191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692026102066,"sku":"724-4191","price":95.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e97876b17e5c7b6ee77d87ef4abc655c.jpg?v=1788292148","url":"https:\/\/voomisupply.com\/products\/value-collection-724-4191-roughing-finishing-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
