Review on 🛠 Bosch TC300 Masonry Drill with Improved Shank for Enhanced Performance by Francisco Holmes

This bit worked very well for digging pilot holes for concrete screws in the brick exterior of my house. I've drilled four holes and the drill is already starting to slow down a bit. I think that's just part of drilling a solid wall, not the drill's fault. I'd say if you drill more than five holes you might want to get more than one.
