Hi Bob,
I am interested in the CAT R8 tool holders I ordered a couple from DD and wondered how yours are coming along can you give me any information as to which size pull stud your using?
The amount of Bellville's needed, and if you have experienced any slippage etc.
Are you grinding the tool holders after Heat treating? etc.

Any info would be helpful. Also if your running Mach3 I have developed a ATC Screen set and Macro unlike anything else Ive seen.

Be Safe Sam
