Abstract: A bracket assembly for the spot-facing of holes of difficult access in a workpiece includes a lower generally horizontally disposed support base, an upper elongated hollow member coupled to said base and having a relatively narrow projecting front end which is dimensioned to reach into workpiece recesses of difficult access, and a rotatable main drive shaft and a rotatable tool arbour carried by the upper member spaced from one another. The assembly also includes means for coupling the main drive shaft to the tool arbour to permit the main drive shaft to drive the tool arbour.
