Abstract

A power tool includes a housing assembly having a housing portion and an arm extending upwardly from the housing portion. The arm has an outer surface. The power tool also includes a drive unit supported by the arm. The drive unit is operable to drive a tool element to work on a work piece. The power tool further includes a collection assembly operable to collect debris generated by the tool element working on the work piece. The collection assembly includes a collection chute assembly having an inlet and an outlet. The collection chute assembly is positionable on the arm to define, between the inlet and the outlet, a first path for debris around one side of the outer surface of the arm and a second path for debris around the other side of the outer surface of the arm.
