Technical Examples

A coring bit provides easy core removal by utilizing a series of lateral blades which extend from the top cutting surface to the base of the bit. The lateral blades and inner faces of the coring bit are biased to provide a conical shape to the core thus permitting the core to be easily extracted. Vents positioned approximate the lateral blades allow chips, debris and waste to be quickly dispelled. Various types of small center drill bits aid in the initial coring stages.
