Model” KKZ” Fixed Drill Reamer

Model “KKZ” Three-cones Reamer (Reamer as shortened below) is a kind of tool used to ream the existing borehole diameter during drilling process. Usually, it is put into the bottom hole with a drill bit so as to simultaneously implement drilling and reaming. Little drill bit used together with a reamer can reduce tripping time and speed up drilling.
