Installation firms often come across situations where they need to create openings in assembled or fixed metal structures, parts or devices. If these openings are to be made well and quickly, in complicated positions to boot, such as overhead, then magnetic drills are the ideal solution.
A magnetic drill is essentially a combination of a hand-held drill and a stand with an electromagnet. After the magnet is activated, it is drawn to all ferromagnetic materials (such as iron, steel, etc.), creating a firm connection between the drill and the machined material. The magnitude of the holding force is affected by the type of material itself, as well as its wall thickness and the quality of the workpiece surface.
The magnetic drill represents an ideal machine set for drilling with spiral, but particularly core drill bits. These differ from spiral drill bits by not drilling off the entire area of the opening, but only its circumference, which significantly increases the work efficiency. In addition, such a compact machine delivers high accuracy, excellent controllability and good manoeuvrability – the drill is sufficiently small to be used even in tight spaces.
