The Reammate Underreamer has been designed with two large, robust cutter arms
which facilitate increased cross-sectional area at the underreamer cutter pockets. This
also provides more room for larger sealed bearing and PDC cutters for optimized
underreaming performance. Gun-drilled ports through the tool deliver more fluid, giving
the operator greater control over the distribution of fluid across the bit and the
underreamer cutters.
The ability to run more drilling weight on the tool and spend more time on bottom
results in cost-effective underreaming. The ability to ensure an existing pilot hole up to
70 percent makes this product ideal for a range of drilling and remedial operations.
Customized cutting structures are available for a broad range of applications and
formation types. Sealed bearing milled tooth and TCI cutters are designed specifically
for underreaming operations and are capable of delivering penetration rates and
cutting structure life comparable to the drill bit. PDC cutters are also available for long
Fluid flow has been optimized using gun-drilled ports to deliver more drilling mud to the
underreamer cutters and the drill bit. This improves hole cleaning efficiency and
accomodates the fluid requirements of other downhole tools.
