Wet Blast to remove drill droplets
Droplets (granular protrusions) generated on the coating applied to the tool surface are removed without damaging the coating film.
Problems with conventional processing
- Three-dimensional workpieces have some parts that are difficult to polish with a polish grinder or the like.
- The coating film is also scraped at the same time as droplets are removed.
- Difficult to automate polishing process.
Comparison before and after processing

The treated surface becomes shiny without scratches. *Not visible to the naked eye.

The black dots are the droplets.
* The black spots after processing are traces of threshing (dents from which droplets have been removed).
