Tricone Bits

Browse our wide variety of Tricone Rock Bits
Tricone Bits, developed in the early 1930's, was a big improvement over the two cone Roller Bit. Because of its versatility and performance, it's still one of the main Rock Bits in use today.
The IADC Code describes a tricone bit, it tells you what the bit is, steel tooth or button, what formations the bit is meant for, and the bearing type. These codes help the driller describe what type of tricone they are looking for. 
Roschen offers a variety of tricones, from sealed bearing button(TCI) bits to open bearing steel tooth bits in a wide range of sizes, in new, rebuilt, and unused/surplus.

Sealed Roller Bearings

Sealed Roller Bearings have some of the features of the non-sealed open bearings, but longer lifetime because the bearings are sealed with an O' Ring Seal.


A lubrication and compensator system prevents leakage into the bearing system and stops the possibility of debris blocking the bearing as well as leakage of grease.


Sealed Journal Bearings

Sealed Journal Bearings have very good durability and wear resistance. Instead of rollers inside the cone there is a floating bushing.


The bushing is usually made out of special material that is highly resistant to heat and galling (surface damage).
