To properly clean some duct systems it may be necessary to “cut-in” to attach a negative air machine or to access areas for contact vacuuming. Air-Care offers 3 hole cutters that will work in 18 gauge or lighter steel.
1. The Drill-powered shear will cut straight or slight curves, as well as making 90 degree corners. It requires a half inch pilot hole to get started and is easily attached to your cordless or electric drill (not included).
2. The adjustable circular hole cutter is the easiest to use. It requires a cordless or electric drill (not included), and will drill its own 1/8 inch center hole. The sliding/locking center pivot pin has a built in scale to cut precise holes from 2 to 12 inches in diameter.
3. The Air Powered Nibbler tool will cut straight, round or any irregular shape, but it requires a 1⁄2 inch pilot hole to get started. It comes with a QD 21 male air fitting and runs on 90 psi @ 20 CFM.
