Precision-hardened keys are lighter in weight and enable shorter shank lengths.
The shank design offers the highest piston-to-bit weight ratio, maximizing energy at the button face.
An airflow channel design and control minimize bit face plugging and eliminate unwanted pressurization of surrounding formations.
Custom and standard sizes are available up to 43 inches in diameter.
Full-gauge underreamers are designed for overburden conditions.
Thanks to SHANDIKE’s long history in drilling, we understand bits. First and foremost, we recognize the significance of a durable, effective design leading your tooling down the hole. Art Holte invented the key drive system. Consequently, our complete line of reverse circulation bits can be quickly changed with hand tools.
Precision-hardened keys are the cornerstone of our key drive system, replacing traditional splines. This allows for shorter shank lengths and lighter weight bits with very high piston-to-bit weight ratios. Delivering maximum energy to the button face means the drill is efficiently bringing rock chips to the surface, rather than wasting time creating dust.
Tapered airflow channels reduce the likelihood of bit face plugging to ensure the hammer continues to operate 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—making drilling in sensitive sites less risky.
SHANDIKE RC bits are available in a variety of shank styles. An innovative two-piece design utilizes tungsten carbide or optional diamond buttons for the utmost in durability. Sizes range up to 43 inches (1092mm). Our flexible design, manufacturing, and heat treatment processes are capable of adapting to meet your needs. RC underreamer bits are also available.
