Standard Abrasives 7000121636 Disc Backing Pad Type S

Product Description

The STANDARD ABRASIVES 7000121636 is a Quick-Change Type S disc backing pad designed to mount and secure quick-change abrasive discs for grinding, blending, and finishing operations. It accepts a 0.25 inch shank and is rated to a maximum of 40,000 RPM, making it suitable for use with die grinders and high-speed rotary tools. The medium-density construction provides controlled flex during surface work, helping maintain consistent disc contact across the workpiece. This backing pad is a standard component in metal fabrication, weld blending, and surface preparation workflows used by machinists, fabricators, and industrial maintenance technicians.

This backing pad is used in applications where quick disc changes are required without tool disassembly. The Type S quick-change interface locks and releases abrasive discs rapidly, reducing downtime during multi-step finishing processes. Typical environments include automotive body work, structural steel fabrication, and maintenance grinding on metal surfaces. It is compatible with die grinders fitted with a 0.25 inch collet and accepts Type S quick-change discs of the appropriate diameter.

Key Features

• Quick-Change Type S interface for fast disc swaps without additional tools
• Rated to 40,000 RPM for use with standard pneumatic and electric die grinders
• 0.25 inch shank fits standard die grinder collets
• Medium density construction supports consistent disc contact and controlled flexibility
• Compact and lightweight at 0.03 pounds for reduced operator fatigue during extended use

Compatibility

Designed as an OEM-style replacement or standard-fit backing pad for die grinders with a 0.25 inch collet, compatible with Quick-Change Type S abrasive discs.

Installation Notes

Installation is performed by threading the 0.25 inch shank into a die grinder collet and tightening to the tool manufacturer's specified torque using the appropriate collet wrench. Ensure the grinder is disconnected from air supply or electrical power before mounting or removing the backing pad. Do not exceed the 40,000 RPM rating of the pad. Always confirm that the abrasive disc mounted to the pad also carries a speed rating equal to or greater than the operating RPM of the tool.
