It features a 4 mm cutting diameter with a 0.25 mm corner radius, a 4 mm length of cut, and an AlTiN (aluminum titanium nitride) coating that extends tool life at elevated cutting temperatures. The micrograin carbide substrate supports sharp edge retention and dimensional stability. With a 6 mm shank diameter and 57 mm overall length, this single-end, centercutting tool is suited for finish milling, contouring, and ramping operations in hardened and abrasive workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers for light to medium stock removal and finishing passes on ferrous and non-ferrous metals, including hardened steels and stainless. The centercutting geometry allows direct plunge entry. The 30-degree helix angle promotes smooth chip evacuation in slotting, profiling, and peripheral milling operations. Extended reach of 30 mm provides clearance in deep pocket and tall workpiece setups. It is installed and run by CNC machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating for high-temperature resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for sharp, stable cutting edges\u003c\/li\u003e\n  \u003cli\u003e0.25 mm corner radius reduces stress concentration and improves corner finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilled pilot holes\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix promotes efficient chip evacuation in slotting and profiling\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 30 mm suitable for deep pocket and tall fixturing setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill compatible with standard CNC milling tool holders accepting a 6 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified CNC machinist or tooling technician. Seat the 6 mm shank fully and evenly in a collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specification. Confirm runout with a dial indicator before initiating a cut. Do not exceed the manufacturer-recommended cutting parameters for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\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: 4 mm (0.8661 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.25 mm (0.0098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.75 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: 12177362\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67988306100530,"sku":"12177362","price":76.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9ac7d539ec094548a28266fb9ceb933.jpg?v=1792291100","url":"https:\/\/voomisupply.com\/products\/accupro-12177362-corner-radius-end-mill-4mm-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
