The Dust Buddie is your solution to the dust cloud created when cutting concrete with a worm drive or hypoid circular saw. It is universal for 7-1/4" worm drive and hypoid circular saws. Using vacuum suction, it captures up to 99% of the dust created when cutting concrete and stone products. Six non-marking wheels allow the shroud and tool to glide with ease to keep cuts straighter and prevent damage to your work surface. There are no tools required for installation. The simple hook-and-loop attachment method allows you to get to work faster without hassle. This shroud is made of a durable blend of polycarbonate & ABS attached to a stainless steel base plate. Two rubber dust shields collect dust from both the front and (optionally) back of the blade. The Dust Buddie complies with OSHA silica laws and EPA regulations for point-of-origin dust collection. For full performance, use this shroud with a vacuum rated at 120 CFM or greater such as the Dustless HEPA Wet Dry Vacuum. This product connects to 1.25" and 1.5" hose cuffs using the included adapter. Includes (1) Dust Buddie, (1) primary front rubber dust shield, (1) optional rear rubber dust shield, (1) 1.5" x 1.5" swivel cuff adapter, (1) front spacer, and (1) releasable tie for keeping the hose out of the way.
