BB2055 Series TiSiN-Coated BF2055 Series Braight Finish

Excellent wear Resistance
Our reamers feature a TiSiN nano-coating, applied at a temperature below 500°C. This coating delivers exceptional wear resistance and outstanding performance against abrasive wear, even in extreme operating temperatures. It also offers excellent high-temperature oxidation resistance, significantly extending tool life. This makes it the ideal choice for demanding applications such as steel milling, finishing inserts, drilling in low-alloy steels, bevel gear machining, and working with tool steel and hot-work steel.
