CS Unitec MAB 525 SB Product Release

CS Unitec’s MAB 525 SB portable magnetic drill features a swivel base for easier positioning when drilling on overhead or vertical surfaces. When attached to the workpiece, the drill provides 20° movement left and right and 5/8” forward and backward allowing the operator to adjust the center for precise drilling without deactivating the magnet and manually moving the drill.

The MAB 525 SB has a hole cutting capacity up to 2-1/2” dia. in structural steel and other metals. The 14.5 amp, double-insulated, reversible motor has a 2-speed oil bath gearbox (70-280 and 180-580 RPM) ideal for annular cutters and twist drills. Additional capabilities include twist drilling up to 1” dia., tapping up to 15/16” dia., reaming up to 7/8” dia. and countersinking up to 2”. This unit has a quick-change keyless cutter system for 3/4” Weldon Shanks, saving time and money. With a 3/4” drill chuck or MT3, the MAB 525 SB easily converts to a standard drill press with a 5” stroke for conventional twist drills.

Integrated sensors in the MAB 525 SB include magnet overheating protection, visual magnet adhesion indication and an Electronic Safety Shutoff Sensor to automatically shut down the drill motor if the magnet loses contact with the material. An internal cable routing system helps protect the motor power cord from external damage. The magnet has a holding force of 8,000 lbs.
