Core drilling machines developed by APS GmbH are dedicated to the preparation of high-quality samples from uniform and non-uniform materials like rocks, concrete, asphalt or other materials. As the quality of the cut surfaces has a major influence on the test results, the coring process is performed in a rigid frame and under well controlled conditions. Resulting cores are smooth and free of surface grooves.

Devices are powered by a selection of high-end electric motors with up to four-speed gearboxes to provide high torque drilling capability throughout the drilling speed range. The simplicity of changing gears via the mechanical switch provides quick and reliable adjustment according to the specifications of corers in use.

An additional drive system enables a stepless control over the drill feed rate in a range of 0.01 to 1.00 mm/s. In the advanced version also an additional information about the torque is available to fine tune the feed rate for more sensitive samples.
