MT-CVD coated carbide grade with a hard substrate and very smooth surface. Ideal for high speed cutting of cast irons.

Coated carbide grade for high cutting speed applications, excellent solution to massive production with stable conditions.

Substrate grade binary (Wc & Co) with medium grain size combined with the medium temperature coating. Suitable for heavy roughing to roughing operations of cast irons with interruped cut at medium to low cutting speeds.

PVD coated carbide grade with large thickness coated grade for heavy roughing applications. Can work in all type of materials and endures a lot of vibration.
