  • PRODUCT DETAILS

Reaming shell is set with natural or synthetic diamond or hard alloy such as PCD, which is designed to be placed behind the core bit to ensure hole gauge and to assist core barrel stabilization. This ensures that when a new core bit is inserted into a continuing bore hole there is a good chance of reaching the bottom of the bore hole without reaming, the another function 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.

Combined high quality and sophisticated design make China Geo-Equip Tech’s reaming shells are the best in the industry. With several different types, we've got you covered no matter what your requirements are. Please contact our sales representative to get an advice for your project.
