Kern Deudiam develops a universal adapter for drilling bits

For years, various German demolition companies have been asking the VDMA (German Machinery Manufacturers Association) for a connection for standard 1" 1/4 bits that is faster and more convenient than the 1" 1/4 UNC connection that is always have used.

In order to respond to these requests and to make all demolition work easier, the VDMA together with manufacturers of drilling and diamond machinery have developed the new POLYGON tool free PQ6 connection.

A universal adapter

The main advantage of this connection is that coupling is easy and fast, although it has other virtues, such as quick connection and disconnection.

Likewise, changing the drill bits is easier for the operator since it is not necessary to use wrenches to unscrew the coupling, nor is there a risk that the drill bit will become welded to the axis of the machine, as happens on countless occasions.

On the other hand, its ergonomic design means that, during assembly and disassembly, the user, the machine and the drilling equipment are protected.

This socket has a hexagonal shape, so when the perforation is horizontal, the bit supports itself and allows the operator who is in charge of the perforation to have their hands free to screw and unscrew the bits more easily. Therefore, this tool will save the operator time and provide great comfort during his work.

On the other hand, it must be taken into account that this drill with quick connection is recommended to work with a maximum diameter of 350.

different possibilities

In order to adapt to the different needs, this adapter can be acquired in different ways, and even ask for PQ6 direct thread drills or obtain PQ6 connectors to couple to 1” 1/4 UNC machines so that the customer does not have to to change all your equipment. Finally, you can get PQ6 connectors at 1” 1/4 UNC or at M41 for the bits.
