Reverse Circulation Down The Hole Bits 2018-11-02T10:12:02+00:00

Project Description

Reverse Circulation Bits

  • Precision hardened keys are lighter weight and facilitate short shank lengths

  • Shank design gives highest Piston-to-Bit weight ratio—maximizing button face energy

  • Airflow channel design and control minimizes Bit face plugging and eliminates unwanted pressurization of surrounding formations

  • Custom and standard sizes up to 43” diameter

  • Concentric, Eccentric, and Full Gauge Underreamers for Overburden conditions

Holte Reverse Circulation Bits Offer Control

Thanks to Holte’s long history with drilling, we understand bits.  First of all, we know the importance of having a durable, effective, design leading your tooling down the hole. Art Holte invented the key drive system.  As a result, our complete line of reverse circulation bits can be changed quickly with hand tools.
Precision, hardened, keys are the core of our key drive system, taking the place of traditional splines. Due to this, they allow shorter shank length and lighter weight bits with very high piston-to-bit weight ratios. Delivering maximum energy to the button face means the drill is bringing rock chips to the surface, rather than wasting time making dust.
Tapered airflow channels reduce the chance of bit face plugging to ensure the hammer keeps running in all types of conditions. Careful control of airflow better directs air to the center of the bit face, helping to eliminate the unwanted pressurization of surrounding formations—above all making drilling in sensitive sites less risky.
Holte RC bits are available in a variety of shank styles. An innovative two piece design utilizing tungsten carbide or optional diamond buttons for the ultimate in durability. Sizes range up to 43” (1092mm).  Our flexible design, manufacturing and heat treatment process is capable of adapting to meet your needs. RC underreamer bits are also available.
