This Driver Shaft is a passive fit to prevent excess torque upon insertion. It has a canula near the open end which allows one to use a steel ligature to secure the TAD during insertion. It also compliments the Collet Driver during removal (The Collet driver works best for insertion)
In this 'initial order', Introductory Kit, one gets the standard driver shaft, handle, 2 pilot hole drills (1.1mm, and 1.9mm) the Instrument box and 4 TADS (You specify which 4 TADS). This will give you everything you need to get started!
