Pneumatic saw provides power and reciprocating motion to blades. Used with Power Hack Saw Blades (sold separately), this saw cuts plastic, steel, stainless steel, and C900/C905 PVC pipe. These model improvements include more powerful air motor, up to 20% faster cutting performance and adjustable exhaust flow air direction. It turns and works freely, along with starting easy and running smoothly. As a safety feature, a trigger lock prevents accidental “on” if the trigger is bumped or pressed unintentionally. It needs 6” clearance beyond the pipe to accommodate blade movement. Optional Blade Guides provide directional guidance for the saw. Maximum capacity is blade and blade guide dependent. Saw It cuts up to 24” diameter pipe when used with the It Vise and a 12” chain extension. It cuts up to 20” (500 mm) diameter pipe when used with recommended blade guide. Pneumatic saws are less likely to ignite materials than gas-powered saws and even some electrical-powered saws.
