Material: The cutting elements of a PDC reamer are made from polycrystalline diamond, which is more durable and wear-resistant compared to traditional hard metal materials.
Cutting Performance: PDC materials have extremely high hardness and thermal stability, allowing the reamer to perform well in cutting through hard rock formations.
Design: PDC reamers are typically designed with multiple cutting teeth and specific geometries that effectively expand the borehole diameter while maintaining good hole wall quality. In HDD projects, the reamer configuration should also be matched with the HDD PDC bit and formation conditions used during drilling.
Stability: Compared to other types of reaming tools, PDC reamers offer greater stability due to their more uniform cutting edges and reduced wear
