differences of quick change extensions for pc

[Ralph René]

Hi,

I would like to order some Quick Change extension for my air graver and have a question about the difference in using the single index or quad index.

Is it necessary to change the position of the pc's set screw if I change from normal graver to one of the quick change extensions while the other quick change works with same set screw position? Or is there no difference?

Or are there differences for these two types in angle between it's index and set screw?

Thank you
Ralph Rene

Hi Ralph, Use the same set screw position as a normal graver. If wanting to turn the graver 45 degrees though you'd use the bottom setscrew hole. The index is the same as the normal graver, it will just extend you're graver out further.
