SANDVIK DNMG 150612-SMR GC1105 TURNING INSERT
The SANDVIK DNMG 150612-SMR GC1105 is a high-performance negative turning insert specifically designed for finishing and semi-finishing operations on stainless steels, titanium alloys, and nickel-based superalloys. The SMR chipbreaker geometry provides excellent chip control at low feed rates, making it particularly effective for light cutting applications where superior surface finish is required.
Featuring a 1.2 mm nose radius, the insert allows higher feed rates while improving cutting edge strength and machining stability.
The GC1105 grade is manufactured on a fine-grain carbide substrate and coated with advanced PVD TiAlN (Titanium Aluminum Nitride) technology. This combination delivers outstanding heat resistance, low friction, and exceptional wear resistance. It significantly reduces built-up edge (BUE) when machining stainless steels (ISO M) and superalloys (ISO S), resulting in extended tool life and consistent machining performance.
Designed for stable machining conditions and continuous cutting operations, the GC1105 grade enables high cutting speeds while maintaining excellent dimensional accuracy and superior surface quality.
