I've searched and posted on another thread, but couldn't find anything and got advised by the moderator to start a new thread, I apologise if this has already been debated.
In my country, the highly praised 3m 710W is not easily available and at prohibitive cost, however, I can get rolls of 50 Cubitron 150mm in different grits at a reasonable price when in bulk, i.e. 3M 31651 is 80grit
They seem to me like the same product with the only difference being a centre punch hole.
Does anyone know if they are the same, or have any experience with them?
