This is great for knurling as the tool holder absorbs all the pressure.
This also relieves any undue strain on the lathe bearings.
Holder size: 3/8” x 3/8” x 5 3/4”
Working Capacity: 1/8” to 1”
The good: it makes decent knurls in soft metals for thumb screws and handles The bad: the frame lacks stiffness and has a tendency to walk the tool towards the chuck as the wheels get out of axis Also, you have to punch out pins to change wheels, where there could very well be screws instead
