Drill Droplet Removal With Wet Blasting

Wet blasting has also been used extensively to remove droplets from cutting tools without causing any damage after the tool has been coated. At the same time, this processing can also reduce surface roughness.

Droplets (granular protrusions and particles) generated on the coating, such as PVD applied to the cutting tool surface, are removed without damaging the coating film, improving welding resistance and defect resistance.

It also relieves the tensile stress on the CVD-coated surface, improving the wear resistance of the cemented carbide tip's cutting edge.
