3M 7100038755 Disc Backing Pad Quick-change Type S

Product Description

The 3M 7100038755 is a Quick-Change Type S disc backing pad designed for use with rotary grinders and pneumatic die grinders in professional fabrication, metalworking, and surface prep applications. It accepts a 1/4-20 female thread for secure attachment to compatible tool spindles and supports a maximum operating speed of 30,000 RPM. The medium-density construction provides controlled flex during grinding and finishing passes, helping to maintain consistent contact across the work surface. Licensed tradespeople and shop technicians working with abrasive disc systems will find this pad suited for high-speed material removal and blending tasks.

This backing pad is intended for use with Roloc TS Quick-Change Type S abrasive discs in shop and field environments. Typical applications include weld blending, rust removal, surface conditioning, and edge work on metal substrates. The Quick-Change Type S interface allows rapid disc swaps without additional tooling, reducing downtime during repetitive operations. It is well-suited for professional use in HVAC fabrication shops, metal trades, and general industrial maintenance settings.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with rotary abrasive tooling. Before mounting the backing pad, ensure the tool is disconnected from its air supply or power source. Thread the pad fully onto the tool spindle and verify it is seated securely before attaching an abrasive disc. Never exceed the 30,000 RPM maximum rated speed, and always verify that any mounted abrasive disc is rated at or above the operating speed of the tool.
