Palmer Bit Company has developed a new design for the Diamond Devil PDC bit. It drills faster and more economically in a wider range of formations. The new full bottom flushing Diamond Devil PDC design flushes cuttings away from the cutters faster, cleans the bit better and helps prevent build-up of the formation in the nose of the bit. The new bottom flushing bits are available in sizes 3 7/8 and up.www.palmerbit.com
