Stop Wasting Time on Manual Cutting
Cutting rectangular holes for electrical switch boxes is the most tedious part of any wiring job. Using a traditional drywall saw or a jigsaw creates a huge dust mess, leaves uneven edges, and takes way too much time. If you cut the hole too big, the outlet box won't hold, and you have to waste hours patching the wall.
The FLEXSHOP Slot Cutter Blade is a game-changer. Simply attach it to your standard oscillating multi-tool, push it against the drywall, and it punches out a flawless, perfectly-sized square or rectangle in under 5 seconds. The box fits tightly on the first try, every single time.

Cut single or double gang box holes effortlessly.
2. Universal Multi-Tool Compatibility
Designed with a universal arbor type that fits 99% of oscillating multi-tools on the market (including brands like DeWalt, Makita, Bosch, Milwaukee, and standard generic tools).
