Products - Z-Bits

The Z-Bit's unique off set configuration is designed to combat side-tracking while reaming downhole.

The Z-bit is run under gauge below a hole opener. The rolling/cutting motion enables the Z-bit to work its way into the hole, followed by a hole opener to open the hole up to a full gauge.


The powerful flushing action through the center of the cone and through a nozzle in the shank above the cutter keeps the hole clean and the teeth clear.

If you are having trouble getting a bull nose hole opener or a drilling assembly to the bottom, the Z-Bit can ream to the bottom without side-tracking the well.

Sizes: 5-¾”, 8-½” and 12-¼”
