Feature of Our Reamer Drill Bits
1. applicable to reaming for first-grade and second-grade larger-diameter hole. It can reduce the sectional area between bit blade and rock hole, also solve the problem of large diameter's low drilling speed in the hard formation with good directive.
2. With Pilot adaptors, the drilling direction can be ensured and accurate.
3. ideal for use with rotary steerable drilling systems, providing a wellbore quality not achievable with other reaming tools. Superior wellbore quality, coupled with a proven history of performance, makes the Reamer the choice for underreaming operations.
