PR1535 - MEGACOAT NANOFor difficult-to-cut materials and stainless steels
2
PR1535• Most suitable for heat resistant alloy, titanium alloy and stainless steel.
• Reduction of sudden fracturing when machining scale or interrupted cutting.
• Reliable new tough grade for difficult-to-cut materials (for S35/M35/P35).
1. High fracture toughness by new mixing ratio of cobalt2. Stability improvement by optimization and homogenization
of the matrix particles
3. MEGACOAT NANO• Stabilized turning operation and long tool life by special nano
coating layer MEGACOAT NANO.• Prevents wear and fracture by high hardness (35 GPa) and su-
perior oxidation resistance (oxidation temperature 1,150 °C).
