Quick-Change Backup Pad for Sanders

This 3M 14216 backup pad accepts quick-change abrasive discs using the TS mounting system. It threads onto a 1/4 in.-20 spindle on compatible sanders. The rubber construction provides a hard-density surface that resists deformation under load. Rated for 20,000 RPM maximum operating speed, it suits high-speed finishing tasks.

Best for detail finishing; not for vacuum extraction

Technicians working on small contours or tight corners benefit from the 3 in diameter and non-vacuum design. The quick-change interface speeds disc swaps during multi-step jobs. Shops needing integrated dust extraction should choose a vacuum-ready pad instead. Users with larger panel work will find the compact face limiting.

20,000 RPM speed rating governs tool compatibility

The pad must only run on sanders that do not exceed this speed. Exceeding the limit risks disc separation and operator injury. Verify the sander nameplate matches or stays below 20,000 RPM before fitting. The 1/4 in.-20 threaded hole is the sole mounting requirement.

Questions about this item

How long will the 3 in rubber pad last at the 20,000 RPM maximum speed?

The hard-density rubber backup pad is rated for continuous operation at 20,000 RPM; actual service life depends on the abrasive discs used and the pressure applied during sanding.

Does the 14216 generate noticeable heat or vibration during extended use?

The rubber construction absorbs vibration, and the non-vacuum design has no fan or motor, so heat build-up is minimal when the correct disc speed is maintained.

What tool and arbor are required to mount this TS quick-change pad?

A rotary tool with a 1/4 in.-20 threaded spindle is needed; the pad threads directly onto that arbor using the TS quick-change system.
