The INCREDIBIT fractures rock in a random elliptical pattern allowing it to be productive in all kinds of soils and formations. Because of the “dancing” effect, the INCREDIBIT bores a larger hole than conventional bits. In most conditions, a 2 ¾-inch bit will cut approximately a 4-inch hole, a 3-inch bit will cut approximately a 5-inch hole, a 3 ½-inch bit will cut approximately a 6-inch hole, and a 4 1/8-inch bit will cut approximately an 8-inch hole. 888.313.7455, railhead.com
