Quick-Change Backup Pad Adapter

The 3M 45102 adapter connects quick-change abrasive discs to a rotary tool. It fits tools with a straight shank and accepts discs with a threaded mounting hole. This accessory is built for metalworking and surface preparation tasks where fast disc changes are required.

Threaded Connector Limits

The adapter uses a 1/4 In.-20 threaded hole for the abrasive side and a 1/4 in straight shank for the tool side. It supports compatible wheel diameters from a minimum of 3/4 in up to a maximum of 4 in. Wheel thickness is not a constrained parameter for this adapter.

4 5/8 Inch Overall Length

The overall length measures 4 5/8 in, which determines the reach and clearance between the tool body and the workpiece. Buyers needing a shorter or longer standoff distance should verify this dimension against their specific application requirements.

Questions about this item

Should I pick the 1/4 in. -20 threaded hole or a different mounting size for my sander?

This adapter uses a 1/4 in. -20 threaded hole on the abrasive side and a 1/4 in. straight shank on the tool side; choose it when your quick-change discs and sander match those exact connections.

What does the 4 5/8 in. overall length mean once the adapter is mounted in a die grinder?

The 4 5/8 in. overall length sets how far the backup pad sits from the tool nose, giving you reach into tight areas while keeping the disc centred on the spindle.

Does the TR quick-change interface limit the disc size I can run?

The TR quick-change interface on this adapter accepts discs from 3/4 in. up to 4 in. diameter, so any TR-style disc within that range will lock securely.
