A
special lightweight, thin wall, carbide-tipped design,
weighing fifty percent less than traditional core
drills allows CS Unitec Core Drills to meet far less
resistance when drilling into masonry and concrete
materials. Drilling speed is up to thirty five percent
faster than with core bits constructed with a heavier
wall thickness.
An innovative self-locking mechanism, for securing
the pilot drill, eliminates the need for set screws
or a pilot drill that must depend on a taper fit to
stay in place. By using a unique ball locking operations
that hammer operator has no need for extra tools or
knockout pins for removing the pilot drill after the
hole being drilled is located. Ideal for horizontal
or vertical drilling in masonry and concrete materials. |
