Hi.

I've bought a Bosch GOP18V-28 multi cutter and its dust extractor attachment (see attached).

However, none of my existing GAS 18V-10L dust extractor attachments marry up to the multi-cutter attachment.

Which part do I need? Is it this one:  https://www.amazon.co.uk/Bosch-2609256-%C2%B0F28-Universal-Adaptor-Universal-Cleaner/dp/B075H4NVJB ?

Or is there something better/more suited?

Thanks.
