- Similar vacuum extraction rates vs. other multi-holed and screen-type abrasives (while using multi-hole back-up pad)
- Enhanced extraction rates vs. standard 5″ five-hole and 6″ six-hole discs; 90% mineral coverage.
- Dust migration between the disc and back-up pad improves surrounding air conditions.
- Easy Alignment: use five larger holes to align.
- Ideal for use with 56320 (5″ {127 mm} Dia.) or 56321 (6″ {155 mm} Dia.) multi-hole sanding pad.
