The short answer: compare the listed backing system, not just the working diameter
YiouTools currently has distinct listings for a 100mm Soft Rubber Backer Pad, a Flexible Rubber Backer Pad, an Aluminum Snail Lock Backer Pad Holder, and a Wool Felt Buffing Pad with Snail Lock Backing. The title, selectable size and stated connection language are useful starting points; they do not establish a universal machine fit.

FAQ
Does Snail Lock mean every polishing machine is compatible?
No. It identifies a connection term on the relevant product listing. The holder, machine and process compatibility still require confirmation.
Can I choose by 100mm or 125mm alone?
No. Size is one check. The backing/holder connection and intended process must also match.
