Works great!

Does what it says it will do.

Great backing plates...

These backing plates mate perfectly with HTD's grinding and smoothing discs. They are very robust and come protected on both sides of the discs to ensure gap-free mating of discs to plates. My only complaint is that on some of the discs, the edges were a bit rough. While that does not bother me visually, the rougher texture does seem to catch dust/slurry and require a bit more care when cleaning (I clean my discs after each use with a nylon brush starting from the finest grit down to the coarse grits). This, however, does not affect the performance of the backing plates at all and I will happily purchase more as I add different discs to my set.

I have only used the smoothing/polishing discs. I have not used a diamond disc on these(bought them pre-assembled). They do what I need them to do. No issues.

Kim DeDominicis

Sturdy and a must with all Diamond and smoothing discs. They should be packaged with them. They are very pricey.

Great product as usual!

HiTech products are always solid. I have bought several backer discs and the tolerances are always tight, engineered to perfection. Super fast shipping as well. Will be back again soon.
