It features a 3\/8-inch mill diameter, a 0.02-inch corner radius, and four right-hand spiral flutes with a 40-degree helix angle. The cutting edges are coated with TiCN (Titanium Carbonitride), which increases surface hardness and wear resistance compared to uncoated carbide. The micrograin carbide substrate supports tight tolerances and consistent performance in ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC programmers in job shops, production facilities, and tool rooms.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for profile milling, slotting, and contouring operations where a controlled corner radius is required to reduce stress concentrations in the workpiece. The centercutting design allows plunge entry into the material. The single-end configuration and 3\/8-inch straight shank make it compatible with standard collet chucks and end mill holders used on vertical machining centers and manual knee mills. The 7\/8-inch length of cut and 2.5-inch overall length position it for general-purpose work at moderate depths without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02-inch corner radius reduces edge chipping on the workpiece and extends tool life in radius-specific applications\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves hardness and lubricity for longer run times in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction holds tighter tolerances than standard carbide grades\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smoother surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for use in standard CNC and manual spindle configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 3\/8-inch collet chucks and end mill holders on vertical machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholder torque requirements and runout specifications. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Inspect the shank and collet bore for chips or contamination before seating the tool. Confirm holder projection and cutting depth are set per the job setup sheet before initiating the machining cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 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: 7\/8 inches (1.0000 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 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\u003c\/strong\u003e: 0.0200 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\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: TiCN\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\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: 0.12 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: 12182542\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736716476722,"sku":"12182542","price":64.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e6ff764feb723d35a8ffb4fb0f455ac.jpg?v=1788779506","url":"https:\/\/voomisupply.com\/products\/accupro-12182542-corner-radius-end-mill-3-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
