It's has two set screws that just bite onto tool steel it does not budge I did some serious cuts with it today 3.5 mm diameter cut on steel it did not budge after several cuts like this ,the tool holder also has the option to screw a grub screw up behind the tool to stop it sliding down as I threaded a small bit on the underside were the hss slides in ,this can also be used to assist tool height adjustment if using the tool on a 4 way tool post.NICE ! I am sold on TT holders too.
Just curious whether the set screw holding the bit goes into a notch or just bites into the tool?
Actually, it's tangential, but who's counting?This type of tool holder goes way back in history, but did use some means of positive locking of the tool bit, I think, for one, the OK tool Company made such a device, it would be TANGENTAL, NOT tanginal.
Count me as a counter, I stand (also) corrected!Actually, it's tangential, but who's counting?
