Acrylic backing plates
Hi-Tech Diamond acrylic backing plates are made out of acrylic and provide an extremely flat surface for disc application. Hi-Tech Diamond 3/8" acrylic backing plates provide an extremely flat surface to back diamond smoothing discs, electroplated diamond discs, Tech-11 polishing pads and final polishing pads.
All acrylic backing plates have a 1/2" arbor hole.
Purchasing note: Color of backing plate may vary.
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.
Sturdy and a must with all Diamond and smoothing discs. They should be packaged with them. They are very pricey.
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.
Good stiffness. Flat and runs true. A good value and shipped timely.
Used it with the foam backing to mount a leather polishing buff. It's working well!
Good Quality and arrived quickly.
