It carries a 1 inch cutting diameter, a 1-1\/4 inch length of cut, and a 5 inch overall length, with a matching 1 inch straight shank. The 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in abrasive or high-speed applications. The micrograin carbide substrate supports sharp edge retention. This tool is designed for use in CNC machining centers and manual milling equipment.\u003c\/p\u003e\u003cp\u003eThis end mill suits production and toolroom environments where close-tolerance profiling, slotting, and peripheral milling are required. Its three-flute geometry balances chip load capacity with flute volume, making it well-suited for moderate to aggressive material removal rates. The right-hand cut and right-hand spiral flute direction are standard for conventional CNC spindle configurations. Centercutting capability allows direct plunge entry without a pre-drilled start hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with a mill diameter tolerance of +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch length of cut within a 1.25 to 1.50 inch length-of-cut range\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eZrN coating for improved heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for sharp, durable cutting edges\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports direct plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and milling machines accepting a 1 inch straight shank, right-hand spindle configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Verify that the tool holder bore and collet are clean and within tolerance before seating the shank to the specified depth. Confirm spindle direction is right-hand before operation. Follow shop safety protocols and machine manufacturer guidelines for tool change procedures, including ensuring the spindle is fully stopped and the machine is in a safe state before handling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.25 to 1.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 315054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740462678322,"sku":"315054","price":410.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/efdee7260b61aa08ccad2cd134d79fb9.jpg?v=1788825168","url":"https:\/\/voomisupply.com\/products\/accupro-315054-square-end-mill-1-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
