Introduction

The reaming shell is an extremely important structural component in the wire-line core drilling tools, which has the functions of righting, diameter maintaining and reaming. The unique spiral carcass design of the reamer can increase the contact with the borehole wall, enhance the drilling stability, and reduce the shaking during drilling. Our reamer can be used with core pipes of various specifications, with high wear resistance and long service life. We can provide Q series (NQ, PQ, BQ, HQ) and domestic size specifications, or customized production according to customer' needs.
