Central Pneumatic's Air Saw - Tool Of The Month

1. Central Pneumatic's saw (item number 113-1VGA at harborfreight.com) is lightweight and will cut through sheetmetal up to 16 gauge thick. Three blades of varying tooth count are included. The handy blade guard is also adjustable to set the dept of the cut.

2. When cutting a hole, you'll need to drill a starter hole to sink the blade into. After scribing the diameter of the hole, we center punched a drill mark just inside of it.

3. Next, we drilled a 3/8-inch hole into the core support and then inserted the saw blade. With 90 psi coming from our Bend Pak air compressor, the saw cut a clean path through the metal like a hot knife through butter.
