Magswitch MagJig switchable jig magnet for downward clamping
Available
The Magswitch MagJig is a small switchable magnet that sits in a hole in a fixture and clamps work down onto it. To drill a hole in the fixture, drop the MagJig in and use it for downward pressure clamping. It is made for woodworking, welding and fabrication jigs. The magnetic field turns completely on and off by turning the knob, needs no electrical power, and the magnet stays clean.
It comes in four models: MagJig 60, 95, 150 and 235. The model number is a name, not a pull rating. Breakaway, the force needed to pull the magnet off clean, flat, thick steel, is not a safe working load. To choose, start with the thickness of the steel being clamped and the downward force the job needs, then move up a size for heavier work. Thin steel holds much less than thick steel, so always test in your own application.
