    Abstract: 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.

    Abstract: A cutting tool, a drill for instance, having a drill body and a cutting portion. The cutting portion comprises a central cutting insert and two peripheral cutting inserts. A cutting edge extends along the three inserts. The inserts comprise surfaces for facilitating a tight connection between the parts of the cutting edge. The peripheral inserts consist of a material of greater hardness than the material in the central insert, and therefore the cutting edge is adapted for the varying cutting speeds in the radial direction of the tool.

    Abstract: A boring device adapted for deep well drilling wherein a cutting plate is fixed in operative position in a recess of a boring head by means of a clamping bolt. The cutting plate is reversible and its position in the boring head is adapted to be adjusted in a substantially radial direction. The cutting plate has a serrated surface and the bottom of the recess has a matingly serrated surface which when contacting each other enhance the clamping action of the clamping bolt.
