ABSTRACT:
A roller bit cutter comprises a tough, metallic, generally conical and fracture resistant core having a hollow interior, the core defining an axis; an annular, metallic, radial bearing layer carried by the core at the interior thereof to support the core for rotation, the bearing layer extending about the core axis; a wear resistant outer metallic layer on the exterior of the core; metallic teeth integral with the core and protruding outwardly therefrom, at least some of the teeth spaced about the axis; and an impact and wear resistant layer on each tooth to provide hard cutting edges as the bit cutter is rotated about the core.
