With a 1\/4 inch cutting diameter and 1\/2 inch length of cut, this single-end tool delivers controlled material removal in ferrous and non-ferrous applications. The 5-flute configuration increases chip load capacity compared to standard 4-flute designs, supporting higher feed rates in finishing passes. A variable helix angle at 38 degrees reduces harmonic vibration and chatter during cutting. The nACRo coating provides elevated heat resistance and lubricity, extending tool life in dry or near-dry cutting conditions. Designed for use in CNC machining centers, this end mill is selected by machinists and tool-and-die professionals working to tight tolerances.\u003c\/p\u003e\u003cp\u003eThe GWS 120981 is suited for finish milling, contouring, and profiling operations on a range of workpiece materials including steels, stainless alloys, and cast irons. Its submicron carbide grade provides the edge toughness required for high-speed applications. The standard length configuration and 1\/4 inch square shank allow direct installation in standard collet chucks and end mill holders without extended-reach adapters. This end mill fits operations where vibration control and surface finish quality are the primary concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute geometry increases feed rate capability and improves surface finish over lower flute-count alternatives\u003c\/li\u003e\n\u003cli\u003eVariable helix at 38 degrees reduces chatter and vibration during cutting passes\u003c\/li\u003e\n\u003cli\u003enACRo coating delivers high-temperature resistance and reduced tool wear in dry machining\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade provides consistent edge integrity across the full length of cut\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction with upcut flute type for standard CNC spindle operation\u003c\/li\u003e\n\u003cli\u003eSingle-end design with square shank for direct mounting in collet or end mill holder\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank square end mill for use in CNC machining centers and manual mills equipped with compatible collet chucks or end mill holders accepting 1\/4 inch round square-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Secure the shank to the full recommended engagement depth in the collet or holder to prevent pullout during cutting. Verify runout with a dial indicator before beginning production cuts.\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\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.5000 to 0.6000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes, 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: Upcut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1035\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: GWS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 120981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":67592573059378,"sku":"120981","price":81.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65f04677bfdd18c08754079ed70f8d9e_cbae53e8-1c39-4c25-82df-588f23143a38.jpg?v=1790421819","url":"https:\/\/voomisupply.com\/products\/gws-120981-square-end-mill-1-4-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
