It carries a 0.14 inch corner radius and a 3\/8 inch mill diameter, making it well-suited for light-to-medium contouring and edge-breaking operations on precision components. The cutting geometry features two right-hand flutes with right-hand cutting direction, ground from solid carbide for rigidity and wear resistance. A titanium carbonitride (TiCN) coating reduces friction and extends tool life in abrasive or hardened materials. The double-end design effectively doubles the usable cutting life before the tool is retired, lowering cost-per-edge on production runs.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers, vertical mills, and manual knee mills running ferrous and non-ferrous stock. It is appropriate for aerospace, automotive, and general precision machining applications where radiused edges are required to reduce stress concentrations, improve part aesthetics, or meet print callouts. The 3\/8 inch shank diameter fits standard ER collet systems and side-lock holders commonly found in production shop environments. Machinists and CNC operators performing edge profiling, radius blending, or corner-break work on steel, stainless, cast iron, and aluminum will find this tool directly applicable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides superior rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces built-up edge and extends tool life in abrasive and hardened materials\u003c\/li\u003e\n  \u003cli\u003eDouble-end design delivers two usable cutting ends, maximizing value per tool\u003c\/li\u003e\n  \u003cli\u003e0.14 inch corner radius produces consistent, repeatable radiused profiles\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute geometry compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003e0.095 inch tip diameter accommodates tight-corner and blend radius operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or production tool for CNC and manual milling applications requiring a 3\/8 inch shank, 0.14 inch corner radius, and double-end solid carbide corner rounding geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator using a calibrated torque wrench and the appropriate collet or tool holder for a 3\/8 inch shank diameter. Confirm spindle and tool holder are clean and free of chips before seating the tool. Set cutting parameters — speed, feed, and depth of cut — based on workpiece material hardness and machine rigidity; do not rely on generic defaults when machining hardened steels. Inspect both ends of the double-end tool before first use and rotate to the unused end only when the active end shows measurable wear.\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\u003eCorner Radius\u003c\/strong\u003e: 0.14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.095 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 12180355\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738699792690,"sku":"12180355","price":130.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a77fdceed94b266886c0f1f49efd725.jpg?v=1788803034","url":"https:\/\/voomisupply.com\/products\/accupro-12180355-corner-rounding-end-mill-3-8-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
