Within 100 years after the rolling cutter was invented by Hughes (in 1909) all bit plants of the world produce the rolling cutters with uniform pitch between steel and tungsten - carbide inserts on cutter crowns of bits. Disadvantage of rolling cutters with uniform pitch between teeth is that bits w

In site page "About us we are more detailed" we will try to explain the basic ideas new "Ideologies of projection of a cone drilling tool with the locked up spalling" and also why so difficultly there is an exhaustion mastering by bit factories of globe of roller bits with (overbreak) superbreaking

Upon the expiry of 100 years from the date of invention of roller bit we developed a new dynamic theory of interaction of roller bit with the bottom hole!
Dynamic theory of interaction of roller bit with the bottom hole while boring, which shows actual complicated interaction processes of the bit

Operation of a roller bit with superbreaking down (overbreak) or the locked up spalling of rock at well boring, is grounded on scientific established fact, that rocks destroyed by a roller bit in the majority have unique properties: very strong resistance to a compression failure and, rather, easy r

Comparative tests of 30% of UBS-bit in September, 2008 at LebGOKe showed good hardening and cementation shells rolling cutters, both experienced and serial bits to upgrade them by working with the PTA effect, which led to a substantial increase in drilling performance. Therefore, after being subject

It is for the first time in the world that inventors of “Anvik” LLC developed the “Theory of dynamic interaction of the cutter bits with borehole bottom in the process of drilling”, which allows to have a feedback, that is according to the wear of the worked out cutter bits it will be possible to im

The main reason of delaying scientific and technical progress in implementing MSB technology of the RF bit manufacturers is economical. It is caused by a separation of the property of a manufacturer and user of the bits. It is different abroad, where each big company that does mining and sells the u
