Guaranteed not to fall off or get hung up on your saw's arbor.
Holds additional metal or plastic shims to dado blades.
Includes two each of .010", .012", and .015" thick shims.
Shims measure 3-3/16" Outside Diameter x 1-1/4" ID (bore diameter)
These magnet shims are very thin and not very "strong". Please make sure the blade and magnet are VERY clean before applying. If the magnetic shim does not "stick" at first, please flip it over and try the opposite side.
