4-Flute TiN Coated Corner Radius End Mill | High Precision CNC Milling Cutter for Stainless Steel, Aluminum & Alloy | Durable & Smooth Cutting
Product Information
This 4-flute TiN coated corner radius end mill is engineered for precision CNC machining across tough materials like stainless steel, aluminum, titanium, and composites. The TiN coating boosts hardness (up to 2300 HV) and heat resistance (up to 500°C), reducing wear and extending tool life by 30% compared to uncoated models. Its optimized 4-flute design ensures high rigidity and efficient chip evacuation, ideal for high-speed roughing and finishing operations. Available in corner radii from 0.5mm to 5mm (0.02in to 0.2in), it delivers smooth surface finishes (Ra ≤ 0.8μm) and tight tolerances (±0.005mm). Perfect for aerospace, automotive, and mold-making industries, this mill excels in slotting, contouring, and 3D profiling, combining durability with precision for superior machining performance.

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.
