Edge rounding and layer finish using Drag Finish

The Drag Finish process enables a defined and reproducible rounding of cutting edges before coating.  

The sharp and brittle cutting edge created by the grinding process, with microscopically small defects, is honed and provided with a radius adapted to your specifications based on the application, material, and machining parameters. The reduction in surface roughness leads to improved chip flow and reduced tendency to welding. 

The surface polishing after coating to remove droplets further improves chip flow and results in a noticeable increase in performance and precision of the tools.
