Primary uses
What this instrument is on the table to do.
Removes locking screws stuck in a plate. The bit, already spinning clockwise, is set in the screw recess and drilled with very light pressure to the far side of the plate. This frees the screw head from the shaft so the plate lifts off with the heads; the shafts are then taken out with the extraction reamer. It can also deepen a damaged recess so an extraction screw can bite.

1.5, 2.0, 2.5, 3.2, 4.0, 5.0, 6.5 and 7.5, for screw diameters from 1.0 mm up to 7.5 mm (Table 3).
