PEERCHEER offers BQ NQ HQ PQ NQ3 HQ3 PQ3 NWL HWL PWL locking couplings for use with BQ NQ HQ PQ core barrels. BQ NQ HQ PQ locking coupling connects the drill string to the outer-tube assembly and provides a mating surface which the head assembly latches ride against while drilling. BQ NQ HQ PQ locking couplings provide directional control for BQ NQ HQ PQ core barrel assembly through wear resistant stabilizing pads that wear down against the drill hole wall.Q series Locking couplings are available for application in standard DCDMA B N H P size.
PEERCHEER'S locking couplings are made out of high quality alloy steel with a hard-faced latch resting area for better latching reliability.
PEERCHEER offers the option of a TANG which is the tab of steel located on the pin end of the locking coupling.

BQ BWL locking couplingBQ NQ HQ PQ locking coupling types:

A-BQ NQ HQ PQ Full Hole Locking Coupling with tang

B-BQ NQ HQ PQ Full Hole Locking Coupling

C-BQ NQ HQ PQ Conventional Locking Coupling with tang

D-BQ NQ HQ PQ Conventional Locking Coupling

 

NOTE

(1)Conventional type locking coupling has carbide pads.

(2) Full hole type locking coupling is surface hardened.

(3)The box thread of locking coupling is decided by the drill rod thread.
