ABSTRACT:
The present invention relates to a handheld power tool including: a main housing, a rear handle mounted on the main housing and a handle connected to the main housing. A base portion of the main housing has a buffing member in the basal plane. The handle comprises two oppositely disposed side handle members and a front handle joined between the front end portions of the two oppositely disposed side handle members. The two oppositely disposed side handle members tilt (ie are non-parallel) with respect to the basal plane. The present invention has the advantage that during buffing of a workpiece, the operator's wrists need bend to only a small degree to accommodate the non-parallel disposition of the buffing member leading to labour efficiency and reduced wrist tiredness.
