Patented Hex Shank
The first thing to notice about the Versadrive tooling system is the hexagon shank.
This allows the entire range to be fitted into the chuck of any standard drill. The hex design means that the slipping problem of standard tools is eliminated.
The next thing you will notice is the 3 concentric locating holes on alternating sides of the hex.
This allows an extremely accurate hold by the range of Versadrive adapters, and works in conjunction with the quick release mechanism.
