This 8" bit will drill a large enough hole for 6" casing. However, you MUST use a smaller bit, such as our 4" casing bit, to drill the hole first and use this only as a reamer bit.
This bit is specially designed for more difficult wells. This bit has a hollow center to reduce drag on the motor. Also, because it has no center it greatly reduces clay balling up at the tip, the primary cause of slow drilling in clay. It also includes a very high quality carbide hard surfacing on top of hardened steel edge to ensure a long life.
