Bi-center Bits



Our Bi-center series adopts the cutting components with triangle PDC and conical PDC inlayed together, and that increases the bit's lifetime. Set up a slant water hole at reamer, and connect the reamer and pilot with reducing synergy flute, which strengthen the cooling and washing function and ensure the bit's effects.
