Built from micrograin solid carbide, it delivers hardness and edge retention well beyond standard high-speed steel tooling. The 7\/32 inch (0.2188 inch) cutting diameter pairs with a 3\/8 inch length of cut and a 45-degree helix angle for efficient chip evacuation and reduced cutting forces. A zirconium nitride (ZrN) coating adds surface hardness and lubricity, extending tool life in non-ferrous metals, aluminum alloys, and similar materials. This stub-length configuration provides added rigidity during aggressive cuts.\u003c\/p\u003e\u003cp\u003eThis end mill suits CNC machining centers, manual knee mills, and tool-and-die work where a small-diameter, short-flute tool is required. The 1\/4 inch shank diameter fits standard collet chucks and end mill holders common in both production and job-shop environments. Its stub-length designation makes it appropriate for shallow pockets, slots, and profiling passes where tool deflection is a concern. Machinists and tooling specialists working with aluminum, brass, copper, and similar soft metals will find the ZrN coating particularly effective.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating improves surface lubricity and extends tool life in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip flow and reduced cutting pressure\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge milling entries\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eStub-length design maximizes rigidity and minimizes deflection in short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank square end mill compatible with collet chucks, end mill holders, and milling arbors accepting 1\/4 inch shank tooling on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked out before inserting or removing tooling from the collet or holder. Seat the shank to the recommended engagement depth specified by the collet or holder manufacturer. Verify runout with a dial indicator before beginning cuts, particularly when working to tight dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/32 inch (0.2188 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.25 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 313000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738813366578,"sku":"313000","price":59.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00076803334e25587127dccacf824fb5.jpg?v=1788804922","url":"https:\/\/voomisupply.com\/products\/accupro-313000-square-end-mill-7-32-in-2-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
