Hollow Collar Cutters

OM86 hollow cutters are designed to cut away swagged or threaded collars from fasteners so the fastener pin can be easily removed. OM86 hollow cutters are ideal for removing Hi-Shear® rivets.

The rotating cutter is applied to the collar until a sufficient amount of collar material has been removed. The pin is then easily removed with a punch. A microstop cage is typically used to prevent the cutter teeth from contacting and damaging the work surface.
