The DRMS (Drilling Resistance Measurement System), patented, produced and developed by SINT Technology is designed to measure the drilling resistance of stone materials (stone and marble) and mortars.

The system can measure the force needed for drilling and the position of the bit during drilling and is equipped with a software program that allows continuous recording and monitoring of that force in relation to advancement of the bit.

The speed of rotation and penetration speed are kept constant during testing.
