ABSTRACT:
The dust attachment which is used with a spiral saw power tool includes a first attachment portion which at a rear end has a substantially dust-tight fit with a mounting head portion of the tool. The other (forward) end extends beyond a forward edge of the mounting head portion, but such that the spiral saw bit extends beyond the forward edge of the attachment portion by a distance which is slightly greater than that of the thickness of the workpiece. An attaching member such as a screw secures the dust attachment portion to the tool. An dust exit tube extends from a side surface of the attachment portion and communicates with the interior of the attachment portion. The dust exit tube extends at an angle away from the attachment portion toward the rear end thereof.
