The D86 discs have identity issues. Are they a thick disc magnet or a short cylinder? By our definition, they are a disc, as their diameter is larger than their thickness/length, but there is room for debate. They are a nice sized rare earth magnet to handle and utilize in a wide range of projects.

This size is also available in grade N52 as part number D86-N52.
