It features a 13\/32 inch (0.4063 inch) cutting diameter, a 1 inch length of cut, and a 2-3\/4 inch overall length. The 45-degree helix angle promotes aggressive chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating increases surface hardness and reduces friction, extending tool life in demanding applications. The micrograin carbide substrate provides rigidity and wear resistance. This tool is intended for use by machinists and tool-and-die professionals operating CNC mills or manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose milling, slotting, profiling, and contouring in ferrous and non-ferrous metals. The regular length designation makes it appropriate for standard-depth passes without extended-reach setups. The right-hand cutting and right-hand flute direction are compatible with conventional CNC spindle rotation. It is a single-end tool, so the cutting geometry is concentrated at one end for maximum rigidity. Typical applications include production machining shops, toolrooms, and maintenance repair operations requiring consistent, repeatable results in steel, aluminum, and similar workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e13\/32 inch (0.4063 inch) cutting diameter with a tight mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and improves tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flutes compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit cutting tool for standard CNC machining centers and manual mills accepting a 7\/16 inch straight shank, with a shank diameter tolerance of +0.0001 \/ -0.0004 inches for secure collet or end mill holder retention.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended grip length to minimize runout and tool deflection. Verify spindle direction is set to right-hand rotation before initiating 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: 13\/32 inch (0.4063 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (2.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 313238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755018813746,"sku":"313238","price":88.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72bf847d3dbf81e37d4db0b5304ac992.jpg?v=1788950506","url":"https:\/\/voomisupply.com\/products\/accupro-313238-square-end-mill-13-32-in-2-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
