On/Off Workholding Magnets Offer Precision, Strength and Speed

The family of workholding magnets from Master Magnetics (the Magnet Source) are designed to provide welders with fast and easy set-up, precise positioning and enhanced holding strength.

Magnetic Welding Squares

On/Off magnetic welding squares are easy to use: just place the neodymium On/Off magnets on two mating steel surfaces to accurately position material for welding. A simple push of the handle allows users to turn the handle to the "On" position and secure for working. A reverse turn disengages the magnet and allows for safe storage.

Additionally, On/Off magnetic welding squares allow for fast set-up paired with accurate and powerful holding. The magnets, which come with pre-tapped holes on all sides for versatile mounting, work on both flat and round stock.

Although not used for lifting, the pull strength of these magnets ranges between 150 and 1,000 lbs. on flat stock, ensuring secure holding during welding.

Workholding Jig Magnets

The On/Off magnets are constructed with rare earth neodymium magnets, providing increased holding power coupled with strong sheer strength to help prevent side-to-side movement. Permanent magnets do not require any sort of external power source.

Once in place, turn the handle to the "On" position to activate for instant holding force. When done, turn the handle to "Off" to deactivate the magnet for repositioning or storage. Two magnets per fixture are recommended to avoid pivoting.

Workholding jig magnets securely mount to any ferrous table saw, fence or other steel surface with the twist of a knob.

Master Magnetics' On/Off Magnets are suitable for:

  • Holding a cove molding jig in place
  • Creating custom featherboards
  • Holding a repetitive stop in place
  • Creating a fence for power tools.

To create custom jigs and fixtures, use with standard .75" material, drill a hole with a Forstner bit and drop in the On/Off workholding magnet.

The magnets are available in four models, ranging from 95 to 150 lb. pull.
