The bit ranges vary from 2 to 24 inches in diameter, with different face styles like Concave, Convex, and flat. The button shapes and grades include Spherical, Ballistic, and Parabolic. Bits are conditioned by a special manufacturing procedure that establishes a protective cushion on the bits, thus reducing chances of cracking which often occur in hi-impact drilling products.
