The Q-P system is similar to the Q and QTK double tube systems but includes a specialized core lifer case and bit. These components enable change in the water flow by creating a seal which routes water flow to the face of bit, away from the inner-tube – further improving core recovery.
Q is a trademark of Boart Longyear.

Genuine QTM double tube wireline systems are ideal for use in most drilling conditions and are available for application in standard DCDMA hole sizes (A, B, N, H, P).
QTK systems are optimized to allow for a larger core sample while retaining the same hole, low fluid pressure, and robust inner and outer-tubes. QTK systems are offered here in the A, B, and N* sizes.
