The Largest Russian Manufacturer of Rock Bits
Three Cone Rock bits

Three Cone Rock bits produced by UralBMT are sophisticated products made from high quality materials (steel forging, carbide, and others). These Three Cone Rock bits are designed for a multitude of drilling applications including: Gas and Oil production, Mining and Mineral Exploration, Water Well production, Construction, Horizontal and Directional, Geotech, Environmental, and a variety of other industrial uses.

A typical Three Cone Rock bit consists of three cones and three leg sections with journals. Hardsurfacing is applied to leading edge of Leg and Shirttail area, and load areas of journal. Leg and Gage protective flat tungsten carbide inserts are available in the majority of UralBMT rock bits.

Each of the three cones is subjected to detailed processes of carburizing and specialized machine operations.

Bearing structures are available as Open Bearing or Sealed Bearing. Open Bearing configuration can be made up of different combinations of Roller, Ball, and Friction assemblies (examples: Roller Ball Roller (shown in picture), Roller Ball Friction, etc...). The Sealed Bearing configurations are available in either Sealed Journal or Sealed Roller

Each bit is attached to a drill string using a standard Threaded Pin Connection. These Connections are in compliance with established IADC and API specifications.

Cutting structures for Three Cone Rock bits are available in either milled steel teeth or teeth made from tungsten carbide (TCI) (TCI rock bit shown in picture). Rock formations and desired rates of penetration determine types of required cutting structure. UralBMT rock bit cutting structures are in accordance with IADC specifications.

Three Cone Rock bits are offered with a standard variety of air and fluid circulation types including Air Jet Nozzles, and Air Passage to the bearing. A Backflow Valve is available in the majority of the air circulation bits, and prevents pieces of formation from entering the drill string once the air to the bit has been shut down.

Each bit is marked on Pin Connection with a serial number, bit type, manufacturing date, and UralBMT trademark.
