Abstract: Provided is a veined end mill tool blank including a body having at least one cutting edge formed of a veined superabrasive material. An anchoring substrate supports the superabrasive material, the substrate including tungsten carbide (WC). An interface integrally joins the veined superabrasive material with the substrate. For each cutting edge, the tool blank is provided with a slot having a curved surface sintered with the superabrasive material. A locator notch is carved on the veined end mill tool blank relative to the veined superabrasive material as a reference point to aid in locating the superabrasive material on the tool blank. The locator notch engraved on the veined end mill tool blank indicates the location of the superabrasive material on the tool blank, thereby eliminating the need for manually locating coordinates of the superabrasive material during a grinding process by a tool fabricator to achieve a precise grinding.

Abstract: A drill bit for a drill includes at least one flute having a rake face including a flute edge and at least one cutting edge having a profile that extends along at least a portion of a length of the cutting edge, the rake face extending from the cutting edge. A chip breaker formed in the rake face, the chip breaker being a continuous groove located adjacent the cutting edge, the groove having a starting end and an exit end opening into the flute edge, the starting end having a depth that is less than a depth of the exit end of the groove, wherein a shape of the groove at the starting end is different from a shape of the groove at the exit end.
