what to use to cut fiberglass

[wellcraftv20step]

i have the Milwaukee brand multi tool, I use that thing more than any other tool in my truck. Great for cutting shims on a cabinet installation, rgeat for notching studs to burry a wire, cutting back floor base molding when installing the case molding on a door, cutting outlet boxes into the cabinet over the microwave. chamfering moldings. notching the quarter inch reveal on a top hanger cabinet to accept crown molding , square holes in sheet rock for repair,cutting door frames to slip laminate flooring under it. I even used it once to notch hinges in a door when my router broke. i dont know what i did without that tool for so many years. oh and the best part is no dust !. this week i will try it widen the hole for my new switch panel.
