Flap discs feature recyclable aluminum backing
Weiler's Tiger® aluminum-backed abrasive flap discs are designed for aggressive grinding jobs and, according to the company, use the strongest back available in the marketplace, producing less flex for more control. Recyclable aluminum backs will not throw fiberglass dust, considered a contaminant in some industries.
The discs are made with a proprietary cloth containing a combination of grain, grain placement, and grain size on a woven backing material. They are available in 4, 4.5, and 7 in. dia. with zirconium grit sizes from 24 to 120.
