It features a 1-inch mill diameter, a 4-1\/8-inch length of cut, and a 7-inch overall length, placing it in the extra-long category for deep-pocket and extended-reach applications. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) coating provides enhanced surface hardness and heat resistance, extending tool life in high-speed and dry-cutting conditions. This single-end tool is suited for use by machinists and tooling professionals running CNC milling centers.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for deep-cavity milling, slotting, and profiling operations where standard-length tools cannot reach. The extra-long configuration and 1-inch shank diameter make it appropriate for setups requiring extended projection from the spindle nose. Right-hand cutting and right-hand flute direction are standard for conventional CNC machining center spindles. The micrograin carbide substrate supports tight tolerances and repeatable performance across production runs in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch mill diameter with a tight tolerance of +0.000 \/ -0.002 inches for accurate bore and slot sizing\u003c\/li\u003e\n\u003cli\u003e4-1\/8-inch length of cut supports deep-pocket and extended-reach milling operations\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle for efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eZrN coating improves wear resistance and performance in dry or semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC milling machines and machining centers accepting a 1-inch straight shank end mill holder or collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify that the tool holder or collet is rated for the 1-inch shank diameter and that runout is within acceptable limits before beginning a cut. Follow the machine manufacturer guidelines for tool overhang and maximum depth of cut to avoid deflection or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (+0.000 \/ -0.002 inches tolerance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4.125 inches (4-1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch (+0.0001 \/ -0.0004 inches tolerance)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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: 313548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727701279026,"sku":"313548","price":917.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd57187ff085c9b6380c43659e9f52dc.jpg?v=1788681033","url":"https:\/\/voomisupply.com\/products\/accupro-313548-square-end-mill-1-in-2-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
