AC1135U
Carbide Substrate
Special Surface Treatment
The smooth, glossy surface suppresses adhesion and reduces the occurrence of micro-chipping
Adhesion-resistant Layer (TiCN-based)
The use of a TiCN-based composition with excellent adhesion resistance reduces adhesion in fine cutting and low-speed conditions, maintaining high machined surface quality
Chipping-resistant Layer (TiAlBN-based)
The use of an ultra-fine grained TiAlBN-based composition with excellent toughness suppresses unexpected chipping and achieves high stability
High-adhesion Technology
Improved stability with special technology enhancing coating adhesion strength
Chipbreaker Selection (Main Chipbreakers)
SI type
Excellent chip control performance over a wide range of cutting conditions
FF
type
