The APS-438 air powered saw and WrapTrack pipe trolley provide a fast method for cutting hard pipe from 6 in. to 60 in. diameter by 4 in. wall. It is designed for use in power plant construction applications where speed and accuracy are critical. Featuring a 3 HP pneumatic motor, the saw comes with fiberglass reinforced abrasive or diamond tipped carbide blades and the pipe trolley simply clamps around the pipe circumference for rigidly mounting the saw.
