Reaming Shells
We offer two distinct grades of Reaming Shells: Standard and Heavy-Duty. EHWA® Reaming Shells are manufactured with a unique patent-pending design. The design facilitates the transition of the cuttings into the waterway area, resulting in longer life and reduced vibration of the drilling tools.
STANDARD-GRADE REAMING SHELL
Standard Grade Reaming Shells are manufactured with a unique design to facilitate the transition of the cuttings into the waterway area. This design also reduces vibration and utilizes precision set natural diamond for increased abrasion resistance.
Available sizes: B, N, H, P & Oversize.
Additional sizes available on request.
HEAVY-DUTY GRADE REAMING SHELL
Heavy-Duty Grade Reaming Shells are manufactured with an ultra-high abrasion-resistant matrix. Additional features include premium-grade natural diamonds, carbide wear pads, and TSPs, precision set for maximum wear. The helical waterways extend along the length of the core to maximize water flow and removal of cuttings.
Available sizes: B, N, H, & P Oversize N, H, & P.
Additional sizes available on request.
