Natural Diamond Reaming Shell
Diamond reaming shell are important tools to be used together with bits.
It's main functions are:
Maintaining borehole gage.
Improving drill string stability and protecting lower drill string from excessive wear.
Helical type reaming shell provides a good passage for drilling fluids.
The matrix is wearproof and its service life is long.
We provide both impregnated and surface set reaming shells with competitive price.
The surface set Reaming Shells are set natural diamonds outside of the shells, generally, with the stone size 20/30SPC. The rock cutters are flushed smoothly as the well design of the waterways.
Reaming Shell is set with natural or synthetic diamond,and it is used to couple the dril bit with the core barrel. Its main function is to ream the hole to the correct comstant specific diameter which ensures adequate clearance for the core barrel and sufficient clearance for the new bit which replaces an old one.It also acts as a stabilizer for drill bit.
Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability
