Technical recommendation |
Raising of the coating hardness by reducing the friction |
Multi-layer coating |
Low-friction coefficient and high surface hardness |
Good saw blade life because of high surface hardness |
|
|
Universal coating for better saw blade lifetime |
Extreme low friction coefficient and also high surface
hardness |
Good saw blade lifetime at high cutting temperature |
Good surface finish without side pick-ups due to smooth
coating surface |
|
|
50 - 100% higher speed and feed rates |
Over 100% higher cutting and feed rates when sawing steel
tubes and profiles |
Special for drycutting or with insufficient cooling
conditions |
|
|
|
Prevention of side pick-ups |
