Product Description
PQ Wireline Diamond Core Drill Bits
Product Description
PQ Wireline Diamond Bits are impregnated tube core bits designed for core drilling applications. These professional drilling tools feature an outside pipe and an inside pipe that can be conveyed separately to the surface.
The inside pipe includes a core-receiving receptacle at its lower end and a measurement unit at its upper end for on-site acquisition, processing, and storage of drilling data including borehole parameters, core samples, and drilling process metrics.
Applications
- Core drilling in steel plates and other industrial materials
- Used with specialized core drilling machines
- Thin-walled diamond core bits for concrete core sampling
- Compressive strength testing of structural concrete

Advantages
Surface-Set diamond bits are ideal for drilling relatively soft, abrasive, unconsolidated formations where impregnated diamond bits are less effective. They are also recommended for harder formations when equipment limitations prevent optimal use of impregnated diamond bits.
