Not a true 3/8" chisel/bit
The first time i used this 3/8" chisel/bit set, i did find it is not a true 3/8". Had to use a hand chisel to make the 3/8" i wanted. Other than that, if you want to do some extra work on your project i find it is a good set to go with and so far it drills & cuts through hardwoods with no problems.
