Although it is high frequency, there is no separate power box needed. All is integrated into one single motor head, with no three phase power needed, running on single phase 220V-240V. This has been designed to significantly simplify things as not every jobsite has three phase power available. It can drill 500mm on single phase, being able to do this due to its output efficiency. On 16A input, it puts out 3.3kW, which is said to be at the level of 90% efficiency. To put this in perspective, a typical 16A universal motor puts out only about 2.1kW or less on the same input. Agp says that this means that the DM20 is more than half again as powerful as competitors’ units.

Agp is also very proud of its ‘PMSM’ (permanent magnet synchronous motor) technology. Agp states that it is the first to apply this technology to a coring motor, with its performance on the job saying it all. To match this performance, any other motor would need three phase current.  In addition to performance, there are many useful features built into the design. The display can be easily switched between metric and imperial. There is a clearly visible LED load indicator so that the operator can optimise feed pressure. Running on single phase current, is said to make the whole system much easier and more convenient to set up and run. With what Agp says are its amazing output and performance, the company believes the DM20 is sure to be a game changer in the field.

The DM20 is joined by Agp’s new QS600 drill stand, which features a quick release cam-lock cradle system. This makes it much easier and safer for the operator to mount and dismount the motor from the stand, especially in challenging situations, such as on walls, etc. Another distinguishing characteristic of the stand is its ability to mount up to a 500mm core bit without the need for any additional spacer, with it also being able to mount 600mm with the addition of an accessory spacer.

This drill stand has a full range of features, such as built in gear reduction, tilt capability, spirit levels, and wheels. The rig is built for strength but with minimised weight, using a steel reinforced aluminium alloy column and box steel base. Overall, the QS600 drill stand and the DM20 coring motor are designed to be a perfect complement to one another, providing an optimised large diameter core drilling package.
