It carries a 3\/16 inch cutting diameter, a 5\/8 inch length of cut, and a 0.060 inch corner radius. Four right-hand spiral flutes and a centercutting design allow it to plunge, slot, and profile in ferrous and non-ferrous materials. At 2 inches overall length and 0.03 pounds, it fits standard CNC machining centers and manual mills where compact reach and precise corner geometry are required. Machinists and toolroom professionals select this geometry for finishing passes that demand tight radius tolerances.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits production and job-shop environments running ferrous alloys, hardened steels, stainless, and similar materials where TiCN coating provides increased surface hardness and reduced built-up edge. The 3\/16 inch shank diameter matches ER collet chucks, Weldon-style holders, and shrink-fit tooling common in CNC vertical machining centers. Its centercutting capability supports ramping and direct plunge entry, reducing the need for pre-drilled pockets in light-duty applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in demanding cutting operations\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.060 inch corner radius with a tolerance of plus or minus 0.00150 inch for consistent part geometry\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes with centercutting capability for plunge, slot, and profile operations\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch shank diameter with a shank tolerance of -0.0001 to -0.0004 inch for secure toolholder fit\u003c\/li\u003e\n  \u003cli\u003eCompact 2 inch overall length suited for short-reach setups on vertical and horizontal machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct application end mill for CNC and manual milling machines accepting a 3\/16 inch shank diameter in standard collet, Weldon, or shrink-fit toolholders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify collet or chuck runout with a dial indicator before cutting to stay within the published diameter tolerance. Do not exceed the toolholder manufacturer's recommended torque specifications for the collet nut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.00150 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 12182425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754417553714,"sku":"12182425","price":40.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c3087ec0d9585bfc62da7fd8e4d1bbb.jpg?v=1788945186","url":"https:\/\/voomisupply.com\/products\/accupro-12182425-corner-radius-end-mill-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
