An opposite end is covered with a cast matrix material which defines a central bit body. A plurality of integral blades are formed of the cast matrix material and extend axially and radially from the central bit body. Each of the blades is reinforced by a metallic extension which is contained within the matrix material and extends coaxially with each blade.
