No more drilling or clipping.
NV gaming requires, since 1990's all chips be grinded to pieces.
Private company's like Paulson then GPI do it.
There is a mobile company that will come on site and do it in a truck.

If a company like Binions is not going to ask for a new gaming license then they can get away with not grinding them.

Older companies just used a drill press to drill them.
