摘要： A power tool for forming a channel in a concrete work surface comprising: a first section carrying a rotatable shaft extending along a shaft axis; a cutting disc having a substantially circular blade provided on the rotatable shaft by receiving the rotatable shaft through a circular opening of the cutting disc; a first support portion on one side of the cutting disc and a second support portion on the opposite side of the cutting disc which cooperate to hold the cutting disc at an oblique angle relative to the shaft axis, a first locking feature of the first support portion and a second locking feature of the second support portion extend through the circular opening of the cutting disc whereby such locking features cooperate to resist relative rotation of the first and second support portions; a second section for engaging the work surface, the first section being movable relative to the second section such that the cutting disc can be moved into and out of engagement with the work surface in use, wherein an active portion of the periphery of the cutting disc, being the part of the periphery furthest from the rotatable shaft in the direction of the work surface, oscillates along an axis parallel to the shaft axis when the rotatable shaft rotates.
