Standard Abrasives 7000121638 Disc Backing Pad Quick-change

Product Description

The STANDARD ABRASIVES 7000121638 is a Quick-Change Type S disc backing pad designed to mount abrasive quick-change discs for grinding, blending, and finishing work. It accepts a 0.25 inch shank and is rated to a maximum of 25,000 RPM, making it suitable for use with high-speed die grinders and rotary tools common in metal fabrication, weld prep, and surface conditioning applications. The medium-density backing provides consistent disc support across the work surface. Weighing just 0.07 pounds, it adds minimal mass to the tool, which helps reduce operator fatigue during extended use.

This backing pad is suited for metal finishing, deburring, and surface prep tasks in fabrication shops, maintenance environments, and production settings. The Quick-Change Type S interface allows rapid disc swaps without removing the pad from the tool, supporting efficient workflow when cycling through multiple abrasive grits or disc types. It is typically used by metal fabricators, maintenance technicians, and industrial tradespeople working with angle grinders or die grinders on ferrous and non-ferrous materials.

Key Features

• Quick-Change Type S interface for fast, tool-free disc changes
• Maximum rated speed of 25,000 RPM for use with high-speed rotary tools
• 0.25 inch shank diameter fits standard die grinder collets
• Medium-density backing delivers consistent support across abrasive disc surface

Compatibility

Designed for use with Quick-Change Type S abrasive discs on die grinders and rotary tools fitted with a 0.25 inch collet. Specific compatible disc families or model numbers were not provided in the product data.

Installation Notes

Installation is performed by metal fabricators or maintenance technicians using a standard die grinder with a 0.25 inch collet. Ensure the tool is powered off and disconnected from its air supply or electrical source before mounting or removing the backing pad. Do not exceed the 25,000 RPM maximum rated speed. Verify that all abrasive discs mounted to the pad also carry a speed rating equal to or greater than the operating tool speed before use.
