Tru-maxx TRU-RP305M Quick-change Type P Disc Backing Pad

Product Description

The TRU-MAXX TRU-RP305M is a Quick-Change Type P disc backing pad designed for use with rotary grinders, die grinders, and similar abrasive tooling. It accepts a left-hand 3/8-24 threaded spindle and mounts via a 1/4-inch shank for secure chuck engagement. Rated to 20,000 RPM, it is suited for high-speed surface preparation, grinding, and finishing operations. The medium-density construction provides consistent backing support across the abrasive disc face, helping maintain contact uniformity during use. It is compatible with the Quick-Lok quick-change system, allowing fast disc swaps without additional tooling.

This backing pad is intended for use in metalworking, fabrication, and maintenance environments where quick-change abrasive disc systems are standard. Typical applications include weld dressing, surface blending, rust removal, and paint stripping on metal substrates. It is sized for handheld rotary and die grinder platforms used by machinists, maintenance technicians, and fabricators in both shop and field settings.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotary abrasive tooling.

Confirm the spindle thread direction is left-hand before seating the pad to avoid cross-threading. Do not exceed the 20,000 RPM maximum speed rating during operation.
