NEW CORE BIT DESIGN

Radical new design. Enhanced for increased carbide embodiment. Reduced body to drilling diameter decreases 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 systems. Integration with the Ratio-

System provides for fantastic system flexibility.

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 problems associated with drilling

re-enforced concrete are greatly reduced with this new bit design.
