Applications

Also known as a permanent lifting magnet, the diamond core drill is a highly practical power tool widely used in construction, renovation, and home improvement for drilling reinforced concrete. It is commonly used for projects such as underground protective barriers, load-bearing walls, floors, roads, dams, tunnels, and bridges. Additionally, it is essential for drilling cement surfaces for installations including electrical wiring, telephone lines, air conditioning units, gas pipes, drainage systems, fire protection systems, and plumbing fixtures.
