Dewalt DAJHXGQM01 Quick-lock Backing Pad 4.5 in

Product Description

The DEWALT DAJHXGQM01 is a Quick-Lock backing pad designed for use with coated abrasive discs in grinding and surface preparation applications. Measuring 4.5 inches in diameter with a 5/8 inch-11 threaded arbor connection, this medium-grade backing pad provides a stable mounting surface for quick-change abrasive discs. It is compatible with angle grinders and is suited for metal fabrication, weld cleanup, and general surface conditioning work. Tradespeople working in fabrication shops, on structural steel, or in HVAC sheet metal applications will find this pad a standard component for abrasive disc setups.

This backing pad is used in light industrial and commercial settings where coated abrasive discs are changed frequently. The Quick-Lock interface reduces disc swap time during grinding operations. Typical applications include deburring, rust removal, and surface prep on metal substrates. It fits standard angle grinders with a 5/8 inch-11 spindle thread, which is the most common arbor size found on 4.5 inch angle grinders used across trades.

Installation Notes

Installation is performed by threading the backing pad onto the angle grinder spindle by hand, then securing it per the tool manufacturer torque guidance. Always disconnect the grinder from power before mounting or removing the backing pad. Ensure the abrasive disc is rated for the grinder RPM before operating. Inspect the pad for wear or damage before each use and replace if deformation or cracking is present.
