Glenn uses these very effectively on his dust-extractor hose to attach to his lathe up close to the work being sanded – as seen in many of this live demos.
Also great to keep your workshop neat and tidy – have your brush or steel ruler just where you need them.
1¾ inch diameter (43mm dia ) x ¼ inch (6mm) thickness with a counter sink hole.
These retaining magnets are complete with a rubber jacket that together with the steel part forms a system that shields and strengthens the magnet, optimally concentrating the magnetic flux on the rubberized magnetic surface.
The rubber protects sensitive surfaces from being damaged by the magnet and also the extra friction prevent sliding on vertical surfaces.
