Advantages of roller cone bits:1. High-strength and high-toughness
carbide teeth are used to improve the impact resistance of the
teeth and reduce the toothbreakage rate;2. The optimally designed
tooth row number, tooth number, exposed tooth height and unique
alloy tooth shape give full play to thecutting ability and cutting
speed of the drill bit;3. Widely used in petroleum exploration,
mining exploration, geothermal wells, hydrological exploration and
other fields.Our company can provide specific solutions according
to the actual drilling situation, and customize assembled drill
bits of anydiameter, including large-diameter machine pile drill
bits, different types of drill bits, reaming bits, directional
drillingbits, etc. Table of classification of formation
