Twist drill tips, precursor constructions for use in making same, and methods for making and using same |
| abstract |
A torsion drill tip comprising a hardened structure bonded to a substrate at an interface boundary adjacent an end of a substrate, the hardened structure comprising a sintered polycrystalline material comprising hardened particles, the hardened structure having an interface boundary And a plurality of cutting edges configured to be borne into the body in use; Wherein the high hardness end surface comprises a center point or chisel edge and wherein each surface tangent to each surface area is configured to be disposed at an angle significantly different from the axis of rotation of the tip in use, . Methods for making precursor structures and tips as well as precursor structures for use in tip manufacturing are disclosed. |
