With a 1\/8 inch cutting diameter and a 1\/2 inch length of cut, this single-end tool is built for precision work in tight geometries. The 4-flute, right-hand spiral configuration paired with a 40-degree helix angle promotes efficient chip evacuation and a smooth surface finish. An AlTiN coating extends tool life by improving heat resistance and reducing friction at the cutting edge. The micrograin carbide substrate provides the rigidity needed for demanding cutting conditions in both CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in job shops, production machining environments, and toolroom applications where small-diameter, high-accuracy cuts are required. The 1\/8 inch shank diameter matches the cutting diameter, making it compatible with standard collet systems. The regular-length profile and 1-1\/2 inch overall length keep deflection low during light to moderate-depth passes. Licensed machinists and CNC operators working on aluminum, steel, stainless, and similar materials will find this tool appropriate for profiling, slotting, and finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 inch cutting diameter with plus 0.000 \/ minus 0.002 inch mill diameter tolerance for precise fitment\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves thermal resistance and reduces built-up edge during high-speed cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for 1\/8 inch collet chucks and ER-style collet systems used in CNC machining centers and conventional milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator following shop safety procedures. Ensure the spindle is fully stopped and locked out before loading or removing the end mill from the collet. Seat the shank fully into the collet to the recommended insertion depth and torque the collet nut to the tool holder specification. Verify runout at the cutting diameter before beginning a production run to confirm proper seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\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\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inch (1.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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: plus 0.000 \/ minus 0.002 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 \/ minus 0.0004 inch\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: 0.01 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: 12182388\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743527338290,"sku":"12182388","price":24.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e4f17aeb9f41b86812ab0ad7ef1babe.jpg?v=1788848051","url":"https:\/\/voomisupply.com\/products\/accupro-12182388-square-end-mill-1-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
