3M Quick Change Backup Pad 3 in

The 3M 7000119310 is a round rubber backup pad designed for quick-change abrasive discs using the TS mounting system. It features a medium-density construction and a black finish suitable for general surface preparation tasks. The pad measures 3 inches in diameter with an overall length of 12 5/8 inches and a width of 9 1/4 inches. It is rated for a maximum operating speed of 18,000 RPM.

Compatibility check before ordering

Verify that your power tool accepts a 1/4 inch-20 threaded hole connector for secure attachment. Confirm the tool's maximum RPM does not exceed 18,000 to match the pad's safety rating. Ensure your abrasive discs use the TS quick-change system for proper mounting on this pad. Note that this model is a non-vacuum type with no dust extraction holes.

Ideal for TS system users; not for vacuum setups

This pad suits operators using TS quick-change discs on compatible rotary tools running up to 18,000 RPM. It is not intended for tools requiring a different thread size or mounting interface. Buyers needing integrated dust extraction should look at vacuum-style backup pads with perforated surfaces. Those using alternative quick-change systems such as TR or Roloc will require a different pad.
