This 4-flute blue nano-coated corner radius end mill is engineered for high-performance CNC machining in demanding materials like stainless steel, titanium alloys, and hardened steels (HRC50–65). Featuring a micro-grain tungsten carbide substrate (0.4–1μm) and PVD blue nano coating, it reduces friction by 35% and extends tool life by 25% compared to standard tools. The 35° helix angle ensures smooth chip evacuation and minimal vibration, ideal for high-speed operations up to 600m/min in 3D profiling and deep cavity milling. Available in diameters from Φ0.5mm to Φ20mm with extended shank options (50L–150L), it supports aerospace molds, automotive components, and precision engraving. Rigorous testing guarantees ±0.01mm tolerance and Ra <0.2μm surface finishes, while dry cutting compatibility reduces coolant costs by 20%.

Matters needing attention
Not suitable for processing aluminum alloy, plastic parts, key machine, hand drill, ordinary milling machine, please confirm the use of demand, if you have questions, please consult customer service, we will recommend you the right processing plan.
1. Buyers need to know the milling cutter and operating instructions Before using the tool, please measure the tool yaw. When the tool yaw accuracy exceeds 0.01mm, please correct it before cutting. 2. The shorter the length of the tool extension chuck, the better. If the tool extension is longer, it is necessary to reduce the speed, feed speed or cutting amount. 3. In the cutting, if abnormal vibration or sound is generated, please reduce the speed and cutting amount until the situation improves. 4. Steel cooling with spray and jet can improve the effect of milling cutter. 5. Note: It is not suitable for low-speed machines such as bench drill and electric drill.
