The ultimate saw for that money! It would be even better if the sds max connector! I tested it in a granite hardness stone. She drilled at least 2mm per minute without much pressure. After the drilled depth of 20cm and the continuous removal of the drilled material, it was minimally heated, and the hole was flawless! The visual acuity of the teeth did not change. It is true, however, that a more powerful machine is needed for such a diameter!
