The term “set diameter” refers
to the dimension of the matrix body gauge ring diameter
on which diamonds (or synthetic PCD particles) and tungsten-carbide
elements have been physically set in order to preserve
this dimension during drilling. The specifications for
set diameter tolerances to which Dimatec manufactures
reaming shells are given in the following tables.
