Coring Drums and Center Pilot Assembly

 

 

Utilicor utilizes a center pilot hole during the coring process which is essential for proper keyhole core cutting and core reinstatement procedures.

 

The pilot hole, which is cut simultaneously during the coring process, simplifies cores extraction, is a quicker and easier operation for the worker, and allows for the core to be properly manipulated during the reinstatement process. 

 

The Utilicor core puller tool has a rubber stopper which expands and becomes friction tight within the pilot hole.

 

Utilicor’s process of cutting a center pilot hole and utilizing a core puller tool is the only work-safe method for extracting heavy cores cut from the roadway. It is also the only work-safe method to allow for a proper core reinstatement.
