⚡ At a Glance
- • Sanding Performance: Stable contact and balanced pressure for work on flat surfaces
- • Best for: DIYers and tradespeople needing direct Bosch-compatible backing pads
- • Not ideal for: Owners of non-orbital sanders or those needing integrated vacuum systems
Five-inch backing pad constructed from engineering plastics and hard rubber. Eight screw holes and a 25 mm centre opening pair with intake holes to help remove dust and preserve sanding discs.
Cleaner, longer sanding runs, thanks to an 8-hole dust extraction pattern
Eight intake holes work alongside a 25 mm central opening to channel dust away from the abrasive, reducing clogging. The pattern supports active extraction on compatible Bosch sanders and helps maintain abrasive cutting surfaces.
Less clogging keeps abrasives working for longer, reducing interruptions and improving throughput on metal and wood panels.
Firm sandpaper retention, with engineering plastic backboard and hard rubber face
Engineering plastic provides a rigid backing while the hard rubber surface delivers grip for hook and loop sandpaper. Manufacturer guidance recommends pressing firmly and twisting the sanding disc when fitting to secure contact.
Sandpaper stays seated under normal working pressure, improving control and reducing slippage during rapid grinding and polishing.
Quick, direct replacement, thanks to an eight-screw layout matching Bosch fixings
Eight screw holes mirror the fixing pattern on listed Bosch models, allowing removal of the old plate by unscrewing the fasteners and fitting the replacement. The central hole aligns with existing dust ports.
Swap-outs are straightforward for compatible sanders, cutting downtime in workshops and at DIY jobs.
