It features a 3\/8-inch cutting diameter, four flutes, and a 40-degree helix angle with an AlTiN (aluminum titanium nitride) coating that extends tool life in dry or semi-dry cutting of hardened steels, stainless, and cast iron. The 1-3\/8-inch length of cut and 3-inch overall length make it suitable for deeper pocketing and profiling operations. Manufactured from micrograin carbide stock, this end mill delivers consistent dimensional accuracy within a mill diameter tolerance of +0.000\/-0.002 inches. It is centercutting, allowing direct plunge entry into the workpiece. CNC machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is applied in general-purpose milling, profiling, slotting, and contouring on vertical and horizontal machining centers. The extra-long length-of-cut classification suits applications where standard-reach tooling cannot achieve sufficient depth. Right-hand cut and right-hand flute direction make it compatible with conventional CNC spindle configurations. It is appropriate for production and job-shop environments where tool consistency and surface finish in ferrous and non-ferrous materials are critical process requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for extended tool life in high-temperature cutting of hardened and ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtra-long length of cut (1-3\/8 inches) enables deeper pocket and profile operations\u003c\/li\u003e\n  \u003cli\u003eTight shank diameter tolerance (-0.0001\/-0.0004 inches) ensures secure, accurate tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC vertical and horizontal machining centers configured for right-hand cutting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the 3\/8-inch shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer's specifications. Confirm runout with a dial indicator before beginning the first cut to verify proper seating and avoid premature tool wear or workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eCoating\u003c\/strong\u003e: AlTiN\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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: 0.3 pounds\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: 12183413\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747354345778,"sku":"12183413","price":68.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62a29a72db251d04a619c2981bc081f6.jpg?v=1788878939","url":"https:\/\/voomisupply.com\/products\/accupro-12183413-square-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
