NEW CORE BIT DESIGN
Radical new design. Enhanced for increased carbide
embodiment. Reduced body to drilling diameter decreas-
es hole wall friction. Unique new carbide composition
and tip shape. Sturdy high grade chrome molybdenum
steel body. This new core bit design will maximize
drilling speed and tool life up to 30% over other sytems.
The alternating pointed chisel carbide teeth and the
spade carbide teeth are designed to optimize and
enhance each other during the drilling operation. The
chisel tips score and break up the materials as well as
stabilize the core bits’ working characteristics. The
spade tips further break and remove the materials.
Even allows for drilling reinforced concrete. Use Rebar-
Cutter for smaller diameters. See page 7 for details.
