8mm Dia R4*8*16*8*60 4Flutes TiAISiN Carbide Ball Nose End Mill For Carbon Steel Alloy Steel Cast Iron

8mm Dia R4*8*16*8*60 4Flutes TiAISiN Carbide Ball Nose End Mill For Carbon Steel Alloy Steel Cast Iron

Product Description:

The 8mm Diameter R4 Ball Nose End Mill is a high-performance cutting tool engineered for precision 3D contouring, profiling, and surface finishing in complex geometries. Made from ultra-fine grain tungsten carbide, this tool delivers excellent durability and wear resistance, even under high-speed machining conditions.

Featuring a 4 mm corner radius (R4) and 4-flute design, it provides smooth cutting action, superior chip evacuation, and enhanced surface finish. The TiAlSiN (Titanium Aluminum Silicon Nitride) coating ensures exceptional heat resistance and oxidation stability, making it ideal for machining hardened steels, alloys, and difficult materials.
