Hexagonal hollow steel mainly is to look at the inside diameter, and the hollow round steel mainly is to look at the outside diameter.

It needs to be hollow hexagonal steel cut, reoccupy soldering machine on its head and tail, the last to mount drill bit chisel. These are all part of it's very important for the drill rod. We at work often used as a type of alloy steel head, because it is in addition to have good functional, the price is not high, its cost is low, and the specifications of the drill bit is usually 36 mm to 44 mm.
