Reaming shells consist of premium grade natural or synthetic
diamonds set into spiral panels on the outside diameter of the
shell, which are suitable to use in all conditions form broken and
abrasive to consolidated and non-abrasive formations.
The outside diameter of the reaming shell is fractionally larger
than the outside diameter of the core bit, there are Tungsten
carbide (TC) reaming shell and diamond reaming shell, currently we
only focus on diamond reaming shell, below are regular Q series
reamer shells outer diameters.

Our impregnated diamond core bits are the most commonly useful bits
in the mineral exploration industry, as they have the widest range
of application. The carefully selected grades of high quality
synthetic diamond are distributed in the depth of impregnated bit's
matrix series.
Our matrix height ranges from 6mm to 16mm.
