These tool holders are ruggedly built for wide and accurate recessing. Except for the shank, they are hardened and ground throughout. Tapered gib allows accurate adjustment for wear.

Round shank type recess tool holders may be used for internal forming, as well as grooving and chamfering.

Round shank type recess tool holder may also be used for undercuts which cannot be reached by a standard tool working from the main tool slide. The holder may be actuated in several ways, one by a draw bar anchored to a bracket built on to the cross slide or frame of the machine, or by a stop rod in the holder contacting a turned diameter of the part piece.
