G42 Adjustment Screw Drilling Jig

This newly designed tool allows you to convert the adjustment screws of any instrument and obtain the same results. No more adjustment screws chewing through to the key foot, material coming loose and falling off, rendering the instrument unplayable.
The body of the drilling jig is made of hardened steel which will not allow the drill to drift and ensures positive centering of the hole. 6” (152mm) of special PTFE beading is supplied with each drilling jig.
