How to attach a countersunk magnet? The countersunk magnetic ring can be attached to non-ferromagnetic materials with the help of a countersunk screw, for example, to hold a cupboard door closed.

Step 1 – Drill hole

Use the cordless drill driver with the Forstner drill bit attached to drill a flat-bottomed hole into a piece of non-ferromagnetic material, for example, a piece of wood.

The Forstner drill bit will produce a hole of a consistent depth with smooth sides, which is ideal to insert the countersunk magnetic disc into.

A flat drill bit may also be used for this task, however, it will not leave as neat of a hole as the Forstner drill bit due to its sharp pointed end

Step 2 – Insert a countersunk magnet

Clear out the hole of any wood chippings from the drilled hole and insert the countersunk magnetic disc with the countersunk hole facing upwards.

Fasten the countersunk magnets with the flat-headed screws until the screw is flush (level) with the top of the countersunk magnetic disc.
