Precision TiN Coated 4-Flute Corner Radius Cutter - 35° Helix Angle, Extended Shank for 3D Profiling & Aerospace Alloys
Product Information
This 4-flute TiN-coated corner radius end mill is engineered for demanding CNC machining in materials like stainless steel, titanium alloys, and hardened steels (HRC50–65). Featuring a micro-grain tungsten carbide substrate (0.4–1μm) and PVD TiN coating, it reduces friction by 30% and extends tool life by 25% compared to uncoated 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 Φ1mm to Φ20mm with extended shank options (50L–100L), it supports aerospace molds, automotive components, and precision slotting. Rigorously tested for **±0.01mm tolerance**, it guarantees Ra <0.2μm surface finishes, while dry cutting compatibility reduces coolant costs by 20% .

User Instructions
1. Information Required by Buyers for Choosing Tools and Operating Instructions
2.Before using the tool, please measure the tool's deflection. If the deflection exceeds 0.01 mm, correct it before cutting.
3.The shorter the length of the tool extending out of the chuck, the better. If the tool extends too long, reduce the rotational speed, feed rate, or cutting volume.
4.During cutting, if abnormal vibrations or sounds occur, reduce the rotational speed and cutting volume until the situation improves.
5.For steel cooling, spray cooling or jet cooling is preferred, which can enhance the performance of the milling cutter.
