The ability to trim the backplate on flap discs allows operators to use the discs for a longer period of time, increasing disc life by up to 65%. Constructed of nylon 6, the backing is durable, yet trimmable, and much more comfortable to work with than hard plastic. The backing also provides excellent flexibility, making it ideal for applications with corners.


Weldcote's trimmable flap discs are available in 4 1/2, 5, and 6-in. sizes, in both high-quality C-PRIME ceramic grain and high-quality Z-PRIME zirconia grain that promote fast metal removal. Both flap disc materials are offered with a patented 5/8-11-in. built-in hub and a standard 7/8-in. arbor hole and both feature a compressed shape that was developed to increase product life and reduce inventory costs for the end-user.
