Walter CNMG190612-RM5 Diamond Turning Insert
The Walter CNMG190612-RM5 diamond turning insert is a precision-engineered square insert designed for machining hardened steels, cast iron, and heat-resistant alloys. It features dimensions of 19.05 × 6.35 mm with a 1.2 mm nose radius and conforms to the CNMG ISO standard. Its negative rake angle and balanced thickness enable stable cutting under heavy load conditions. The carbide grade used in combination with AlTiN and TiCN multilayer coatings extends tool life by up to 30% compared to similar inserts. The RM5 geometry is optimized for medium to semi-rough turning and delivers effective chip control at high speeds. This insert performs reliably in both continuous and interrupted cutting operations.
The insert’s engineering is based on precision pressing technology and nano-layered coatings, which significantly enhance its mechanical and thermal resistance. The applied cutting geometry evenly distributes stress across the cutting edge, preventing premature cracking. Its optimized corner design improves final surface finish and reduces the need for secondary polishing. Each insert weighs approximately 14.8 grams, striking a balance between mass and rigidity. Compatibility with standard ISO toolholders enables fast tool changes and boosts productivity in manufacturing enviro
