It carries a 0.3543-inch (9.00 mm) mill diameter with a 0.5512-inch (14.00 mm) length of cut and a 2-3\/4-inch overall length. The micrograin carbide substrate paired with an AlTiN finish gives the tool enhanced heat and wear resistance at elevated cutting speeds. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This stub-length end mill is intended for use by machinists and tool-and-die professionals working in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and side milling operations where a compact stub-length tool provides rigidity and minimizes deflection. The centercutting design allows for direct plunge entry into the workpiece. Right-hand cut and right-hand flute configuration follows standard CNC and manual milling conventions. It is applicable in job shop, production machining, and maintenance repair environments requiring tight dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for high-temperature and wear resistance\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling\u003c\/li\u003e\n\u003cli\u003eStub length reduces overhang and minimizes deflection during deep side milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute — compatible with standard spindle direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank replacement end mill for CNC machining centers and manual milling machines accepting a 10.00 mm (0.3937-inch nominal) straight shank with ER or side-lock toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Shank diameter tolerance is -0.0001 to -0.0004 inches, so verify toolholder bore condition and cleanliness before seating. Confirm runout with a dial indicator after clamping to maintain tolerance integrity on finish cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3543 inches (9.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (70.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eFinish\u003c\/strong\u003e: AlTiN\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\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 12182870\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728759324978,"sku":"12182870","price":76.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbfb9d8ebb8cd30497b9bd9f7154f9b6.jpg?v=1788695923","url":"https:\/\/voomisupply.com\/products\/accupro-12182870-square-end-mill-0-3543-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
