Review on 💨 Titanium Spring Loaded with High Speed Automatic Function by Jimmy Jefferson

This is my third set of these bits. They are useful for enlarging previously drilled holes. Bought the last set as my nephew borrowed them to drill a 1/4" panel. Handy for quick drilling instead of wasting time just finding the right size drill bit. No, these aren't expensive hardened drill bits but they do a small job I need to drill buy a set they need a tool from time to time
