OB-3500 magnetic core drilling machine is a portable drilling machine with a magnetic base. It can use twist drill bits, annular cutters, milling cutters, and other rotary cutters.
Magnetic drilling machines with reversible motor and variable speed controls can also perform operations like tapping, countersink, and reaming.
The magnetic drill relies on the adsorption force of the magnetic base to perform drilling operations from different angles. Because of its small size and high power, it is extremely efficient. The magnetic drill solves the problem of removing waste and slag from pipelines and drilling holes in steel plates. Therefore, magnetic drills are widely used in some large-scale subway construction, large-scale equipment maintenance, power plant maintenance, and pipeline engineering.
