The MK-Manta I Core Drill is a powerful all-purpose drilling rig that is designed
to drill holes, up to 12 inches in diameter (14 inches with the 2 inch spacer), in
all types of concrete slabs, floors, walls, and ceilings. The Manta is designed for
easy anchoring using masonry anchors. A secondary vacuum base is provided
to facilitate quick and easy anchoring to smooth floor surfaces.
The Manta is designed for use with a variety of motors. All motors are powerful
two or three speed units that provide the correct cutting speed over a range
of diamond drill sizes. Some models utilizes a shear-pin system for motor
protection, while some others utilize a slip-clutch. See the Drilling Speeds
section of this manual.
The carraige, column and base assembly of the Manta I Core Drill is the strong,
sturdy drilling platform that provides the rigidity needed to quickly drill accurately
placed, straight, smooth holes in all types of concrete. The Manta’s base is
slotted to provide easy anchoring of the drill, in a variety of drilling situations,
with a single masonry anchor. The slot also allows more than one hole to be
drilled from a single anchor location. The base contains four leveling screws to
insure accurate hole alignment even on uneven concrete surfaces. The base
also has a cast in handle and a set of wheels to provide easy transport.The
carraige travel is controlled by a strong rack and pinion gear-system, that can
be locked at any point on the column. The slidding handle allows the operator
to easily control the drilling pressure and speed. At the top of the column is
a strong jack-screw that allows for additional bracing to overhead or opposite
surfaces.
The vacuum base and pump provide quick and reliable mounting to smooth
concrete slab and floor surfaces. The powerful vacuum pump provides 25 PSI of
holding power which equates to over 1800 pounds of force, holding the Manta
securely, for safe, accurate drilling. The pump has a quick disconnect connector
on the hose, as well as an ergonomic handle, to provide ease of transport. The
vacuum base also features leveling screws, a cast-in handle and six inch (6”)
wheels.
The water system for the Manta is a simple hose hook-up and shut-off valve
that provides water under pressure to the diamond drill bit. The water travels to
the center of the bit through the water swivel and spindle to insure that water is
supplied to the cutting end of the bit, even in deep drilling operations.
