Product Description

The roller reamer is used for all kinds of reaming stabilization in drilling operation, especially the function of stabilization in drilling of the abrasive formation. It is a very popular tool for hole size from 4 5/8 to 26". Additionally, it can be used in different hole when same body is equipped with different bearing block and roller. The body is made of modified alloy steel, fully heat treated to 285~341Brinell hardness and 54J minimum impact strength.
