Features & Benefits • Performer non-woven unitized wheels are made by compressing layers of non-woven abrasive materials, with special nylon fibre that adhere with the abrasive. • That grinding process provides self-sharpening of the wheel resulting in consistent quality and a homogenous and even finish. • Used for de-burring and polishing, both in one process only. • Made up of high quality nylon fibre, it removes surface defects & gives decorative finish.
