IADC417 12.25mm tricone bit

Product Description

Tricone Drill Bit is an ideal solution from soft to hard rock formations, it is connected with the drill stem and rotates along
with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously
revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability.
