Built on the Series 1040 platform, it features a 1\/4 inch mill diameter, a 1-1\/8 inch length of cut, and a 3 inch overall length. The nACRo coating provides thermal resistance and wear protection suited to hard and abrasive workpiece materials. The 38-degree variable helix geometry reduces harmonic vibration during cutting, enabling more stable passes at higher feed rates. This tool is sized and configured for use on CNC machining centers, manual mills, and high-speed spindle setups across production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is well suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where heat generation and tool deflection are primary concerns. The single-end, right-hand cutting configuration makes it a direct fit for standard toolholding systems. Machinists and CNC programmers working with hardened steels, stainless alloys, and high-temp alloys will find the nACRo coating and submicron carbide grade particularly relevant to tool life in demanding cut conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute design increases chip load per tooth at high feed rates compared to standard 4-flute geometry\u003c\/li\u003e\n  \u003cli\u003eVariable helix at 38 degrees reduces chatter and harmonic vibration during extended cuts\u003c\/li\u003e\n  \u003cli\u003enACRo coating delivers thermal and oxidation resistance for hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade provides edge integrity and resistance to micro-chipping\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC and manual milling setups\u003c\/li\u003e\n  \u003cli\u003eSquare shank fits directly into collet chucks, end mill holders, and shrink-fit toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application solid carbide end mill for use in standard 1\/4 inch diameter collet chucks, end mill holders, and shrink-fit toolholding systems on CNC machining centers and manual vertical mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\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, locked-out state before changing tooling. Seat the shank to the recommended gauge line depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges under magnification before use and verify runout at the tool tip with a dial indicator before beginning production cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 7\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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eShank Type\u003c\/strong\u003e: Square\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eLength of Cut Range\u003c\/strong\u003e: 1.0000 - 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 122931\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52075001479474,"sku":"122931","price":134.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/630dff8c6611a6a8805b808ea59ecdd2_093f0a7d-2114-4539-af72-16a68d62423d.jpg?v=1790051603","url":"https:\/\/voomisupply.com\/products\/gws-122931-square-end-mill-1-4-in-7-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
