Dynabrade introduces a new series of air powered vacuum disc sanders, available in 2-in., 3-in., 5-in. and 7-in. diameter. The 2-in. and 3-in. models are available in a self-generated vacuum model, in which the tool’s exhaust directs contaminants to a portable self-contained vacuum system, and a central vacuum model, available for connection to external or central vacuum systems. The unique vacuum shroud of each tool diverts dust and debris to the vacuum source, the company says.
