POWER TOOL ATTACHMENT FOR FORMING SPHERICAL OR PARTIALLY SPHERICAL SURFACES
A power tool attachment for forming a spherical or partially spherical surface on a workpiece comprises a bit that is connectable to a rotatable drive head of a power tool. An end of the bit comprises a cutting tool. The power tool attachment further comprises a base engageable with the power tool for bearing against the workpiece. The base comprises at least one annular guide surface dimensioned such that, when the base is engaged with the power tool, the annular guide surface extends around the bit and faces toward or away from a longitudinal axis of the bit for guiding the cutting tool relative to the workpiece to form the spherical or partially spherical surface on the workpiece.

In further embodiments, the surrounding circular part 25 can be provided with outwardly extending teeth and surrounded by a further outer circular part with inwardly extending teeth, to cooperate with the outwardly extending teeth, to provide more complex orbital, oscillatory or impact motion.
