Overview of PDC Hole Opener

PDC Hole drill bit opener is designed for the enlargement of pilot holes and large hole applications. They are also used for road and river crossing applications.

The under reamers hole openers are made of AISI 4145H fully heat-treated alloy steel. All products have carbide grinding teeth and inserting tools. Body and cutters are hard-faced in three different designs with different conditions and rock formations. We also can design of the PDC hole opener blade allows replaced in the field.

As one of drill bit manufacturers in china, we offer innovative drilling technology to mitigate drill string vibration during reaming. Great Drill Bits hole opener solution can help you solve your challenges, whether you use a rotary steerable drill combination, a rotary motor drill combination, or a traditional rotary drilling system. Our reaming tools operate at high efficiency, increase equivalent cycle density (ECD), reduce the risk of fractured formations, reduce torque and drag, and overcome drilling challenges.

The Advantage of PDC Hole Opener

The body is machined out of a single block of heat-treated AISI 4145H alloy steel.

Compared to the roller hole opener, the PDC hole opener performs better during the drilling process. The post-maintenance process is much simpler, just replace the PDC cutter, which can reduce the production cost later.

Depending on the formation and the customer's special requirements, different sizes of PDC hole openers can be produced.

Application

Hole reamer drill bits to make big holes are designed for the enlargement of pilot holes and large hole applications. They are also used for road and river crossing aplications.

Constructure

The hole openers are manufactured from AISI 4 145H fully heat-treated alloy steel. All are available with carbide-milled teeth and insert cutters. Arms and cutters are hardfaced for protection in three iferent designs for varying conditions and rock formations. The design of the hole opener llows for field-changing the cutters.

Cutting stucture

The reamer mainly consists of four or more cones. Cuting Structure with premium tungsten carbide hardfacing or premium tungsten carbide insert of formulas and new techniques is utilized, and increases wear-resistance capability of reamer.
