Operations
Note
THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE
OPERATING THIS MACHINE!
PURPOSE
Ø The purpose of the 4”Z1W/S core drill is to drill through masonry, concrete or other
mineral rock types using annular coring bits.
Ø These drills are designed to be used by hand or bolted to the drilling surface using
the drilling rig.
o NOTE: If using the drilling rig, make sure the base fits completely on the
surface and the base is securely fastened using wedge anchors to bolt to the
surface.
Ø These machines can be used vertically, horizontally or overhead (inverted) provided
an acceptable work environment. NOTE: For safety, when drilling horizontally or
overhead with the drilling rig, a safety chain/strap should always be used.
o CAUTION: If drilling overhead you are only permitted to use dry type core bits
with a vacuum system. “Wet” type holes overhead would allow water into the
motor and create an extremely dangerous situation.
OPERATIONAL PRINCIPLES
Ø The main drilling shaft rotates in a forward clockwise direction. The main drilling
motor connects to the tool spindle to make contact with a surface and slowly bore a
hole. If using the drilling rig, the drill fits inside the C clamp assembly and using the
feed handles on the side of the rig, the user can raise or lower the drilling motor.
Ø These drills are ONLY to be used with diamond impregnated coring bits.
o When drilling with “wet” type bits, the bit ends pulverizes the material and the
water brings the material out of the cut.
o When drilling with “dry” type bits, the bit end pulverizes the material and dust
brings the material out of the cut.
