Purpose of the development: Designed for drilling operations.

Recommended application field: Mines.

Advantages over analogues: Resistance KNTU from 4 to 7 times higher than the serial resistance of the drilling tool. A characteristic feature of the type KNTU crowns: the toughest conditions, the higher the efficiency.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
In contrast to the well-known in the world of blade and pin crown, while drilling that hole in the corner area of ??destruction of rocks blocked the side wall, which reduces the speed and increases the flow of drilling tools, developed in the ISM new way of breaking rocks in a borehole can solve this problem. In the corner area of ??destruction of the rock occurs under the action of shear stresses instead of compression, which significantly reduces the power consumption of the drilling process. To implement this method of drilling has been created entirely new drilling tool - crowns a new technological level (KNTU) that meet all the criteria of the feasibility of launching them into production. KNTU utilized with nominal diameters of 40, 46, 86, 105 and 110 mm. On the prospects of the new drilling tools show the results of comparative industrial tests carried out in the mines of Krivoy Rog Iron Ore Basin. Crowns KNTU compared with serial bits. Resistance KNTU from 4 to 7 times higher than the serial resistance of the drilling tool. A characteristic feature of the type KNTU crowns: the toughest conditions, the higher the efficiency.
