Built from micrograin carbide and coated with titanium carbonitride (TiCN), it delivers high wear resistance and extended tool life in ferrous and non-ferrous materials. The 5\/16 inch diameter tool features a 40-degree helix angle with spiral fluting, promoting smooth chip evacuation and reduced cutting forces. With a 1 inch length of cut and a 4 inch overall length, it falls in the long-series category, offering extended reach where standard-length tools cannot access. Machinists and CNC operators install this tool in vertical machining centers, knee mills, and manual milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits precision machining work in job shops, tool rooms, and production environments. The centercutting geometry allows plunge milling in addition to standard peripheral and slot milling. Right-hand cut and right-hand flute configuration match conventional spindle setups without modification. The long-series length makes it useful for slotting deeper pockets and reaching features on stepped or raised workpiece surfaces. Applications include steel, stainless steel, cast iron, and hardened alloy milling where a TiCN coating provides the thermal and abrasion resistance needed for consistent dimensional results.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and reduces built-up edge in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables both plunge and profile milling operations\u003c\/li\u003e\n  \u003cli\u003eLong-series 4 inch OAL provides extended reach for deep-pocket and step-surface work\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit solid carbide end mill for conventional and CNC milling machines accepting a 5\/16 inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator. Power down the spindle and confirm it has come to a full stop before changing tooling. Seat the shank fully in a collet or end mill holder and torque the drawbar or set screw to the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut, as micrograin carbide is sensitive to deflection and improper seating can cause premature chipping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long Series\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\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181813\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":52031567233330,"sku":"12181813","price":79.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91229a8b4851ac0837b810c16cea8611.jpg?v=1790020208","url":"https:\/\/voomisupply.com\/products\/accupro-12181813-square-end-mill-5-16-in-2-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
