Magnetic backed diamond discs are super-fast to change and available in a wide selection to suit most smoothing and pre-polishing needs. Resin bond discs are great for pre-polishing your glass and stones. The resin that holds the diamond in place uses a more relaxed bond which is perfect for pre-polishing. These discs have a 1" hole to help center on your steel plate. Use in combination with Covington's 12", 18" or 24" Flat Lap Grinder for optimum performance. Available in 12", 18", and 24" sizes.

Works as well as the more expensive discs

We have always used the nickel bond discs. For the price these work just as well. I don't yet know how long they will last.
