and super-long service time.
Description:
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
