Built from micrograin carbide and finished with a TiCN coating, this tool delivers extended wear resistance and improved surface finish in demanding cutting environments. It features a 9\/16 inch cutting diameter, a 3 inch length of cut, and a 40-degree helix angle on a spiral flute geometry. The 2-flute design promotes efficient chip evacuation in slotting and pocketing applications. Machinists and toolroom operators will find this configuration well-suited for long-reach work where a standard-length end mill cannot access the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills. The long-length body — 6 inches overall with a 3 inch length of cut — supports deep-pocket profiling and extended-reach contouring. The centercutting geometry allows for direct plunge entry as well as ramping and helical interpolation. Right-hand cut and right-hand flute configuration matches standard spindle rotation on most milling machines. It is packaged and sold as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for improved hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN finish increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth cutting action and effective chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports plunge milling, ramping, and helical entry\u003c\/li\u003e\n  \u003cli\u003eLong-length profile with 6 inch OAL and 3 inch LOC enables deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit tooling solution for standard 9\/16 inch ER, set-screw, and shrink-fit tool holders used in CNC machining centers and manual milling machines requiring a long-length 2-flute square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Insert the shank fully into the tool holder to maximize rigidity and minimize runout — the shank diameter tolerance of -0.0001 to -0.0004 inches is designed for a controlled fit in precision holders. Verify tool projection and holder clamping torque per the tool holder manufacturer specifications before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiCN\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\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: 0.35 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: 12181765\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732778156338,"sku":"12181765","price":173.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/932de36dc758f66dcb68749d294f4bd6.jpg?v=1788746697","url":"https:\/\/voomisupply.com\/products\/accupro-12181765-square-end-mill-9-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
