Product Details

Reaming rock bit 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.

reaming bits for quarry are designed to enlarge pilot holes for development rounds,

long hole blasting of drop raises and constructing service holes.

With Pilot adaptors, the drilling direction can be ensured and accurate.

Our factory Reamer is 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.

Advantages

Different front designs for various rock formations
Longer service life
Improved hole straightness
Lowest cost per meter drille
