3 Point Roller Reamer

These tools are considered essential under hard rock drilling conditions to prevent under gauged holes and help stabilize the bit. Borex 3 point reamers (bit subs) are fitted with replaceable rollers, pins and bearing blocks. Reamers can be made with a special shoulder on the pin end to accommodate a burn out ring should the customer require this feature. String type roller reamers can be supplied in all sizes on request. Standard size float bores are incorporated into all roller reamers. All roller reamers are supplied with heavy duty plastic thread protectors.
