The Skirt / Chuck off Screen Drill drilled four holes
18mm dia x 100mm deep for the Chuck off screen attachments with the top two
drills. The lower two drills drilled up to six holes 18mm dia x 65mm
- 125mm deep depending on whether the drills encountered reo. The design
for the brackets required two holes @ 125mm deep in a diagonal pattern. The operator of the drill rig located the rig on survey
marks with its push button drive control and pressed start for the rig to
drill its holes. When the holes were completed the operator moved to the
next survey position. This drill was designed and manufactured for the M7
Motorway construction.
