A cutting guide apparatus for use with a portable power cutting tool and including a guide base plate, locking mechanism for removably attaching the cutting guide apparatus to an upper blade guard of the cutting tool, and a control mechanism to control the position of the tool relative to a planar workpiece. The control mechanism includes a slidable member and is slidably disposed on a track which is attached on the guide base plate and moves along the direction of the cut to guide the cutting tool throughout the cutting process. The control mechanism further includes an abutment guide member for abutting against the workpiece to maintain the cutting tool in an accurate cutting position during the cutting process. The abutment guide member is pivotably connected to the slidable member such that when the slidable member has reached the end of the track, the abutment guide member is pivoted upwardly to slide along the upper surface of the workpiece so that the base plate and the cutting tool can continue the cutting process if required. The control mechanism further includes an elastic spring for providing tension so that the slidable member can be returned to its initial position after the cutting process is completed.
