  • Deluxe Rock/Clay Drilling Bit - for 4" Casing

This bit is for drilling wells with 4 inch casing. The actual dimensions on this bit are 5.75", and it can fit inside of 6" schedule 20 PVC pipe.

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. This has a very high quality carbide hard surfacing applied to hardened steel to ensure a long life. Replacements are seldom needed for a single well.

If you expect a lot of clay or rock while drilling your well, consider buying this bit; it can often drill two to three times faster than the general purpose bit, lasts much longer, and drills faster in sand, too.
