Abstract: A vacuum filter bag includes an inlet flange and gasket and a plug. The inlet flange includes axial ribs and recesses which improve the seal between the inlet gasket and a vacuum inlet port and prevent accidental removal of the filter bag from the vacuum inlet port. The plug more securely closes the filter inlet opening after use of the filter bag. The filter bag reduces user exposure to dust and debris captured with a vacuum and is particularly suited for minimizing exposure to hazardous materials.

Abstract: A dust collection shroud for an oscillating tool is provided. The dust collection shroud includes a shroud body with a base and semi-circular dust collection plenums which extends around the output shaft of an oscillating tool. Left and right airflow ducts extend upwardly from the dust collection plenums around the sides of the oscillating tool head. The airflow ducts join together above the oscillating tool. A vacuum port connects the dust collection shroud to a vacuum to collect dust generated while using the dust collection shroud. The dust collection openings and airflow ducts are configured to provide greater airflow from adjacent the front of the oscillating tool in combination with balanced airflow around the sides and back of the oscillating tool; allowing the shroud to be used with various cutting and sanding bits.

Abstract: A circular saw dust collection shroud is provided. The dust collection shroud includes a shroud body and a saw blade hood which is disposed around a circular saw blade. The saw blade hood may engage the upper blade guard of the circular saw. The dust collection shroud is reconfigurable to mount to either a left or a right handed circular saw and is adjustable relative to the saw to position the saw blade hood in a desired location around the saw blade.

Abstract: An angle grinder dust collection shroud includes mounting brackets which are attached to a shroud body via slots which allow the mounting brackets to move to different circumferential locations around the output shaft of the angle grinder as well and inwardly towards and outwardly away from the output shaft of the angle grinder. The mounting brackets are adjustable in their position around the angle grinder output shaft to allow them to engage the angle grinder while avoiding any mounting features for the angle grinder's stock blade guard.

Abstract: A shroud for circular saws is provided. The shroud attaches to the shoe of a circular saw and includes a blade opening to allow the saw blade to pass through the shroud. Dust is collected from the front and back of the blade and directed to a vacuum through an internal plenum. The shroud may include vertical hoods which extend up from the front and back of the blade opening and cooperate with the circular saw blade guard to capture dust and debris. The bottom of the shroud may include wheels to assist in using the shroud and saw.
