It features a 9\/16 inch (0.5625 inch) mill diameter with a matching 9\/16 inch shank diameter and a 2 inch length of cut, providing solid rigidity across the full cutting zone. The 6 inch overall length accommodates deeper setups without sacrificing stability. Built from micrograin solid carbide and coated with an nACRo finish, this end mill is suited for demanding cuts in ferrous and non-ferrous materials. It is a centercutting, right-hand cut, right-hand flute tool intended for use by machinists and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for general milling, profiling, slotting, and plunge operations in CNC machining centers and manual mills. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation, making it a practical choice for production work in steel, stainless, cast iron, and similar materials. The 2-flute configuration is well suited to slotting and work in softer metals where chip clearance is a priority. The extended 6 inch OAL makes it useful for setups requiring additional reach, such as deep pocket milling or work on tall workholding fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16 inch mill diameter with mill diameter tolerance of +0.000 \/ -0.002 inches for precise fit\u003c\/li\u003e\n  \u003cli\u003enACRo coating for improved wear resistance and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shank square end mill for use in CNC machining centers, knee mills, and manual milling machines equipped with collet chucks or end mill holders accepting a 9\/16 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into a collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, and confirm that feeds, speeds, and depth of cut are appropriate for the workpiece material and machine capability.\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 inch)\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)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: nACRo\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 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 inch)\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\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: 0.25 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: 12178855\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731320504626,"sku":"12178855","price":329.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e98bf91d2beda0a70a85bf9403dd92d0.jpg?v=1788729679","url":"https:\/\/voomisupply.com\/products\/accupro-12178855-square-end-mill-9-16-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
