    Inexpensive tool that saves a lot of time, great for home use

    These DIRBUY square slot cutters are a good inexpensive option for occasional drywall work. I have been using them with one of my DeWalt oscillating multi-tools, and the universal mount fits perfectly with no compatibility issues. The set includes both the 3.7 x 3.7 inch square cutter and the smaller 2.4 x 3.7 inch rectangular cutter, which covers the common electrical outlet cutouts I would need around the house.These are very inexpensive blades and somewhat cheap, and I would probably look at better-quality cutters if I were an electrician making these cuts every day. For DIY home projects,

    Great electrical box cut in tool

    These two cut in tools work very well for cutting in electrical boxes into sheetrock. Just mark and then but the tool in the multitool and they cut right in. I have used this type of cut in tool before and they make for such a clean cut and less work to mud around as long as you properly read your tape measure. There is a single gang and double gang tool. Just remember that these are a saw blade and over time they will get dull and need replaced as with any saw blade.
