Eccentric Drill Bits

Eccentric drill bit refers to a drill with asymmetrical distribution of the steel body or carcass around the axis line of the drill bit, so that the center of the bit deviates from the axis line. When the drill bit rotates, a lateral force (centrifugal force) is generated to cut the hole wall and enlarge the hole diameter. The eccentric bit is used to extend the running depth of the casing or the expansion of the easy-to-shrink hole section,Using high wear-resistant tungsten carbide button and high toughness alloy steel body, The high-efficiency drill bit can be optimized and customized according to the rock structure.
