Magnetic Drilling Machine

When used overhead, a magnetic base drill motor must be secured with a safety strap, chain, or cable independent of the magnetic base to prevent the unit from falling if the power fails or the magnet disengages.

A magnetic drill works by engaging a powerful electromagnetic base that locks the tool firmly to a steel workpiece, allowing the motor to drive an annular cutter or drill bit straight down through thick metal without the risk of the drill slipping or twisting out of the operator's hands.

Yes, you can use regular twist drill bits in a magnetic drill by swapping out the annular cutter arbor for a standard drill chuck adapter, though annular cutters are much faster and require less torque for large holes.

A magnetic drill machine is designed to anchor itself securely to flat steel and iron surfaces via a powerful electromagnet, allowing fabricators and ironworkers to drill, tap, ream, and countersink clean, precise holes vertically, horizontally, or overhead directly on structural beams, bridges, and heavy plate steel where standard drill presses cannot go.

Standard portable magnetic drills typically handle hole sizes up to 2 inches to 2-3/8 inches in diameter when using annular cutters, while heavy-duty industrial or specialized multi-purpose mag drills can punch holes up to 3 inches to 4 inches in diameter or larger.
