Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The 3\/8 inch diameter, 4-flute configuration with a 30-degree right-hand helix provides efficient chip evacuation while maintaining a quality surface finish. The square end geometry suits shoulder milling, slotting, and profiling operations. This end mill is a single-end tool with a Weldon flat shank for positive drive in compatible tool holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining steel, alloy steel, stainless steel, and other ferrous materials in job shop, production, and maintenance machining environments. The TiN coating extends tool life in interrupted cuts and abrasive materials. The 1-3\/8 inch length of cut provides adequate reach for most standard milling operations without excessive overhang. It is installed and operated by machinists and toolroom technicians on manual and CNC milling machines equipped with appropriate collet or end mill holders accepting a 3\/8 inch Weldon flat shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for elevated heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree right-hand helix balances chip clearance and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eSquare end geometry supports slotting, profiling, and shoulder milling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and resists pullout in end mill holders\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting design  -  not suited for direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders and collet chucks accepting a 3\/8 inch Weldon flat shank on manual knee mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling setup procedures. Secure the Weldon flat shank fully into the end mill holder, engaging the set screw against the flat to prevent pullout. Verify runout with a dial indicator before beginning cuts. This tool is not centercutting  -  do not use for direct plunge operations; ramp or helical entry is required when starting cuts in solid material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 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\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 724-5088\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67951622914354,"sku":"724-5088","price":39.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bf45475d589306f1a8cf0915d20b6b6.jpg?v=1791731178","url":"https:\/\/voomisupply.com\/products\/value-collection-724-5088-end-mill-3-8in-4-flute-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
