Benchmark Abrasives 7" resin fiber disc backing pad provides the rigid support needed to run 7" resin fiber discs on a right-angle grinder. Its solid thermoplastic construction helps transfer grinding pressure efficiently to the workpiece, making it well suited to aggressive stock removal, weld grinding, beveling, deburring, and other demanding applications.
Raised spiral ribs and ventilation holes promote airflow behind the abrasive disc to help manage heat during use. The rigid plastic construction is lighter than traditional rubber backing pads, while the included lock nut securely holds compatible 7" resin fiber discs in place.

Applications
Use with 7" resin fiber discs for:
Heavy stock removal
Weld removal and blending
Beveling and edge preparation
Deburring
Grinding and shaping
Rust and corrosion removal
Paint and coating removal
Surface preparation
Blending and smoothing
Larger surface grinding applications
Backing Pad Performance
Pad Type: Rigid
Support: Firm
Best For: Aggressive grinding and stock removal
Recommended With: Coarse through fine 7" resin fiber discs
Tip: Rigid backing pads transfer more pressure directly to the abrasive, making them particularly effective for coarse-grit grinding and severe stock removal. The current product page specifically positions this pad for aggressive grinding and coarse-grit sanding.
Safety Tips & Techniques
Inspect the backing pad, lock nut, abrasive disc, and grinder before use.
Do not use a backing pad that is cracked, warped, melted, or excessively worn.
Make sure the resin fiber disc sits flat and is securely fastened before operation.
Never exceed the maximum RPM of the backing pad, abrasive disc, or grinder.
Replace the backing pad if it no longer supports the disc evenly or causes unusual vibration.
