Description
A hand reamer has a longer taper or lead in at the front than a machine reamer. This is to compensate for the difficulty of starting a hole by hand power alone. It also allows the reamer to start straight and reduce the risk of breakage. The flutes may be straight or spiral. Each machine requires a different type and size of reamer. The depth of the hole or surface being also drilled determines the length of the reamer to choose.
