Hole opener Transformer

Prefabricated unit "Transformer" is another development of TECHNOPROK-61 LLC. It consists of a hexagonal shaft, sections of different diameters with cone rollers, retainer nut and spacers. This design significantly reduces the price of a set of hole openers. The hole opener has cone rollers from oil-filled bits with carbide pins.

The rollers are expensive and non-repairable. In case of breakage of the rollers on a specific diameter of the hole opener, you can replace just this section and not the entire tool. It can be used for drilling rocks of up to 12 Protodyakonov hardness scale and requires considerable effort. It is impractical to use it in viscous rocks and soils.
