Is there any way to get an adapter? What is the difference in the one I got and this? https://www.boschtools.com/us/en/boschtools-ocs/cordless-oscillating-multi-tools-ps50bn-43162-p/

i just got this https://www.boschtools.com/us/en/boschtools-ocs/cordless-oscillating-multi-tools-gop12v-28n-188244-p/. I'm looking for two accessories I cannot seem to find. It looks like not much is compatible with this new Starlock configuration? I need something that can grind out a concrete crack so I can fill it and also a sanding head that could sand small areas of concrete. Any ideas?
