With a 9\/32 inch (0.2813 inch) cutting diameter and a 40-degree helix angle, it delivers efficient chip evacuation and clean edge geometry on ferrous and non-ferrous workpieces. The TiCN (titanium carbonitride) coating increases surface hardness and wear resistance, extending tool life in abrasive cutting conditions. This is a stub-length, single-end tool with a right-hand cut and right-hand spiral flute configuration, ground from micrograin carbide for consistent edge quality. Machinists and CNC operators install this tool in standard milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for light to medium material removal in vertical and horizontal milling centers, manual knee mills, and CNC machining centers. The centercutting design allows plunge cutting as well as peripheral and slot milling. Its stub-length configuration (1\/2 inch length of cut, 2 inch overall length) provides added rigidity, making it a practical choice for applications where chatter control and dimensional accuracy are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge sharpness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating for improved hardness and reduced friction in abrasive materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables plunge, slot, and peripheral milling\u003c\/li\u003e\n\u003cli\u003eStub-length body maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5\/16 inch round shank, compatible with ER-style collets and standard end mill holders sized for that shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Power down and lock out the spindle before inserting or removing the tool. Verify shank seating depth and collet condition before operation. Inspect for chipping or coating wear before each use and replace when tolerances can no longer be held.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 inch)\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\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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: Stub\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\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: 12181639\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51779838476594,"sku":"12181639","price":60.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/802c10a75be53082a744674a2c5a0e83.jpg?v=1789175301","url":"https:\/\/voomisupply.com\/products\/accupro-12181639-square-end-mill-9-32-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
