Built from micrograin carbide stock and finished with a nACRo coating, this tool delivers heat and wear resistance suited to harder workpiece materials. The 5-flute geometry combined with a variable helix angle reduces chatter and harmonic vibration during cut, improving surface finish and tool life. With a 5\/16-inch cutting diameter and 7\/16-inch length of cut, it is sized for slotting, profiling, and finishing passes in tight-tolerance work. Right-hand cut and right-hand flute direction are standard. The tool is centercutting, allowing plunge entry.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, vertical mills, and manual knee mills where solid carbide tooling is specified. It suits applications in alloy steels, stainless steel, hardened materials, and similar workpiece families where the nACRo coating provides a measurable advantage over uncoated or TiN-coated tools. Single-end configuration means the tool is replaced rather than indexed when the cutting edge is worn. Machinists, toolroom operators, and CNC programmers in job shops and production environments are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute design increases chip load capacity and feed rate potential compared to 4-flute equivalents at this diameter\u003c\/li\u003e\n\u003cli\u003eVariable helix geometry reduces chatter and vibration during long-duration cuts\u003c\/li\u003e\n\u003cli\u003enACRo coating provides elevated hot hardness and oxidation resistance for harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eMicrograin carbide substrate supports sharp edge retention and resistance to micro-chipping\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute direction for standard spindle setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 5\/16-inch collet or end mill holder setups 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 toolroom technician. Secure the shank fully into a collet, end mill holder, or shrink-fit toolholder to the manufacturer-recommended engagement depth before tightening. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Do not exceed the tool's specified length-of-cut range when programming axial depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inches (0.4375 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: 5\/16 inches (0.3125 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: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\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\u003eLength of Cut Range\u003c\/strong\u003e: 0.300 - 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95168788\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733007106354,"sku":"95168788","price":101.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3506c6e5c6feff169fd50d50e5e7f01_07161fa3-bc58-463c-9e35-65c3893bf7ab.jpg?v=1788750340","url":"https:\/\/voomisupply.com\/products\/accupro-95168788-square-end-mill-5-16-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
