It's quite simple to use this nifty tool. First, decide what type of hole you need to drill. Do you need a rectangular or square hole? Depending on the desired hole, choose the right model to cut your slot. If you plan to put a wall outlet in the hole, make sure it is the right size.
The blade is compatible with all standard oscillating multi-tools . You just need to attach the saw blade, whether square or rectangular, and start using it. With just one punch motion, you'll have your slot completed in no time!
