              Are these discs type 27? Do they come with a depression on the center? Home Depot associated advised me to buy flat disc. However, manual says I need type 27.

                      Nowhere was it made clear that there are two different arbor sizes. Seeing how I need a 5/8” arbor and these have a 7/8” arbor they were useless to me
