The electric hammer drills drilling iron will function with what bit
Another point to note, because the concentricity of the hammer drill is not high, the drill drill swing things badly, is not easy to drill at the same time, because of the drill chuck before and after the virtual is relatively large, so almost drilled when before the punch, causing danger, suggest to buy a separate electric hand drill, good use safety.
Drill iron need straight shank twist drill, but hammer clamping the drill, a need to increase the conversion of chuck, chuck is ordinary twist drill chuck, with a handle can be installed in the upper chuck hammer, to differentiate your hammer with 4 or 2 round pit pit square handle handle to buy the right conversion of chuck.
