Tough™ Diamond Reaming Shell

Diamond Impregnated Pad

Patented technology enables the use of large synthetic diamonds greatly enhancing wear life and eliminating the need for specialty shells in diamond core drilling exploration.

Ready to Ream

Along with exposed diamonds, each pad includes tungsten carbide and thermally stable diamond (TSD) pins on the cutting edge making this reaming shell ready to drill right out of the box.

Adapter Coupling

Available in adapter coupling configurations for extra stability in situations where deviation is a concern (not shown).

Dual Pad

Available in dual pad 10” configurations for straighter holes when deviation is a concern.

Abrasive Reaming Shell

Diamond Impregnated Pad

Using rows of synthetic diamond and TSD pins, abrasive pads generate less torque in the hole than the equivalent reaming shell, while still producing long life.

Diamond Ground

Outer-diameter grinding pre-exposes the diamond and reduces size variation, improving stability and helping produce the longest-lasting reaming shell available.

Heavy Duty

Available with an optional heavy-duty blank to prevent undercutting in extremely broken conditions (standard on oversize versions).

Dual Pad

Available in dual pad 10” configurations for straighter holes when deviation is a concern.
