Claim One:
1. The combination of (a) a portable motorized power head having a driven shaft adapted to receive and hold a cutter or the like, said power head having a predetermined cross-sectional shape in a direction transverse to the axis of said shaft, (b) a portable sleeve having interior surfaces mating to the cross-sectional shape of said power head to receive the latter in longitudinal sliding relationship in a direction parallel to the axis of said shaft while preventing relative rotation of the head and sleeve about such axis, said sleeve being shaped to define two parallel flat surfaces on opposite sides of its exterior, whereby the sleeve may be disposed with one of the flat surfaces resting on a flat support structure and may be clamped to the structure by clamp means engaged with the other flat surface, and said sleeve being adapted at one end to rest for support on a work surface.
