It features a 11\/32 inch (0.3438 inch) cutting diameter and a 1\/2 inch length of cut, with a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate provides hardness and wear resistance suited to demanding cutting environments. A ZrN (zirconium nitride) coating adds surface hardness and reduces friction, extending tool life in ferrous and non-ferrous applications. This tool is installed and operated by machinists and tool-and-die professionals in CNC and manual milling machines.\u003c\/p\u003e\u003cp\u003eThe 313153 is a stub-length end mill with a 2-1\/2 inch overall length and a 3\/8 inch shank diameter, making it well-suited for tight-clearance milling operations where a shorter reach reduces deflection. Its right-hand cutting and right-hand flute direction follow standard milling conventions. The two-flute geometry provides ample chip clearance, making it a practical choice for slotting, profiling, and peripheral milling in both roughing and finishing passes on a range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute direction\u003c\/li\u003e\n\u003cli\u003eStub length profile minimizes deflection in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard square end mill with a 3\/8 inch shank, compatible with any milling machine or CNC machining center collet or end mill holder sized for a 3\/8 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the collet nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 313153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728412803378,"sku":"313153","price":74.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23e87517ac47f038daf9db4eff044514.jpg?v=1788690943","url":"https:\/\/voomisupply.com\/products\/accupro-313153-square-end-mill-11-32-in-2-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
