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.
