The set includes 29 hardened steel ball points with precision polished heads.

The set includes a cubic shaped groove ankle with 11 semicircular grooves from 5 to 26 mm in diameter and two grooves with an angle of 60° and 90° and a set of appropriate cylindrical and angled punches for each groove. The set also includes an anvil on the base. All components are made of high-quality tool steel and hardened accordingly.
