The Milwaukee parts Kit 49-22-5012 is easily adapted to the BOSCH RS5 reciprocating raw for which there is no longer a blade holder repair kit of any kind available through BOSCH parts.
Slight elongation of the clamp screw hole & use of a M5-0.8 socket headed clamp screw fixes the Bosh RS5 And gives it an old school Milwaukee blade clamp.
Ya don't have to throw the tool in the scrap heap.
