It features a 13\/32 inch (0.4062 inch) cutting diameter, a 1 inch length of cut, and a 7\/16 inch shank diameter, with an overall length of 2-3\/4 inches. The three-flute geometry with a 40-degree helix angle and spiral flute design promotes efficient chip evacuation and smooth cutting action. The nACRo finish provides enhanced wear resistance and thermal stability, extending tool life in demanding cutting conditions. This end mill is centercutting, enabling direct plunge entry into workpiece material. Intended for use by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill suits general-purpose milling operations including slotting, profiling, and peripheral milling on ferrous and non-ferrous metals. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining center setups. The micrograin carbide substrate supports tight tolerances and consistent performance across production runs. The 13\/32 inch diameter fits applications where a near-half-inch cutter is required without stepping up to a full 1\/2 inch shank tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13\/32 inch (0.4062 inch) cutting diameter with a mill diameter tolerance of +0.000\/-0.002 inches\u003c\/li\u003e\n\u003cli\u003eSolid carbide micrograin substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003enACRo coating for improved wear resistance and heat resistance\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flute design for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank solid carbide square end mill for use in CNC machining centers and manual mills equipped with collet or end mill holders accepting a 7\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet or tool holder to the recommended engagement depth and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 13\/32 inch (0.4062 inch)\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\u003eLength of Cut\u003c\/strong\u003e: 1 inch (0.4062 decimal range up to 1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\/Coating\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12178891\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755738300722,"sku":"12178891","price":102.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1114717acd782ec7aa9b29a92f58d859_92989f98-8c41-4438-880e-b8b94b4a0d51.jpg?v=1788958921","url":"https:\/\/voomisupply.com\/products\/accupro-12178891-square-end-mill-13-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
