AGP Introduces High Cycle Coring Motor and Drill Stand

Published: 11/9, 2023

Now Taiwan manufacturing AGP is entering the high cycle concrete sawing and drilling segment by launching their new high cycle coring motor DM20 and a new drill stand QS600.

AGP’s new DM20 is an all-new rig mounted coring motor for diameters of 5 to 19.6 in (100 to 500 mm). The state-of-the-art high frequency motor design allows a wide speed range with only a single gear ratio and no loss of torque. There are no gears to select; all speed adjustments are made electronically with its advanced digital interface. Users simply select the diameter by push of a button.

Although the DM20 is high-frequency, no separate three-phase power box is needed. Using permanent magnet synchronous motor (PMSM) technology, the DM20 operates on single-phase 220V-240V, significantly simplifying operation, as not every jobsite has three-phase power available. On 16A input, it puts out 4.4 hp (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 2.8 hp (2.1kW) or less on the same input. AGP claims the DM20 is more than half again as powerful as competitors’ units, again using only single-phase power.

Other features of the DM20 include a display that can be easily switched between metric and imperial measurements, and a clearly visible LED load indicator to help the operator optimize feed pressure.

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 and tight spaces. The stand can accommodate core bits up to 19.6-in (500mm) without the need for any additional spacer. An accessory spacer expands the bit diameter to 23.6 in (600mm).

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 minimized weight, using a steel reinforced aluminum 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 optimized large-diameter core drilling package.
