looks like a tool for installing threaded inserts.
Another $8 US tool. I had to do a bunch of these and boy was it nice and fast...... I should have gotten one 30 years ago..... if they had them back then....... The one pictured is for 1/4-20 out from Rockler. Check page 106 or search for power drive threaded insert tool.......kp91 said:looks like a tool for installing threaded inserts.
