Walter Surface Technologies 04X203 Disc Backing Pad

Product Description

The WALTER SURFACE TECHNOLOGIES 04X203 is a hard-density disc backing pad designed to support twist disc abrasives in grinding and surface preparation applications. Built from molded polyurethane, the pad features a removable 1/4 inch mandrel with a 1/4 inch-20 threaded shaft, allowing quick changeover between discs without replacing the entire assembly. It is rated to 30,000 RPM, making it suitable for use with die grinders and similar high-speed rotary tools. The hard backing density provides firm, consistent pressure transfer to the abrasive surface, which is critical for controlled material removal. Weighing just 0.09 pounds, the pad adds minimal mass to the tool setup.

This backing pad is intended for use with twist quick-change disc systems in industrial, fabrication, and metalworking environments. Typical applications include weld blending, deburring, and surface conditioning on metal workpieces. The twist quick-change compatibility allows technicians to swap abrasive discs rapidly during production without additional hardware, reducing downtime on the bench or in the field. It is suited for professional tradespeople and fabricators working with angle grinders, die grinders, or straight grinders that accept a 1/4 inch shank mount.

Installation Notes

Installation and disc changes should be performed by a qualified technician familiar with abrasive tool safety. Verify that the grinder or die grinder is powered off and disconnected from its power source before mounting or removing the backing pad or abrasive disc. Confirm the tool spindle speed does not exceed the 30,000 RPM rating of the pad before operation. Follow applicable ANSI B11 or OSHA abrasive wheel safety guidelines when mounting and using this accessory.
