3M 7100006170 Soft Interface Disc Pad 5 in Multihole

Product Description

The 3M 7100006170 is a soft interface disc pad designed for use between a backup pad and a sanding disc in surface finishing applications. Built from soft, durable foam, this interface pad adds a conformable layer that allows sanding discs to follow curved surfaces, contours, and edges more closely. It measures 5 inches in diameter by 1/2 inch thick with a 3/4 inch multihole pattern, and weighs 0.09 pounds. Automotive body technicians, collision repair pros, and finishing tradespeople use this pad to improve contact on irregular surfaces and maintain consistent material removal.

This interface pad is suited for use in automotive refinishing and surface prep work where conformability is critical. It is designed to work with 5 inch Hookit Clean Sanding discs, 5 inch Hookit Dust Free discs, and standard 5 inch Hookit discs. When paired with a Clean Sanding Hookit backup pad, the interface layer increases dust extraction efficiency by maintaining disc contact across uneven surfaces. It also delivers the same conformability benefit when used with non-vacuum Hookit discs in dry sanding setups.

Key Features

• Soft durable foam construction increases conformability on contoured and curved surfaces
• Allows sanding discs to follow surface contours and reach closer to edges
• Compatible with vacuum and non-vacuum Hookit disc systems
• Multihole pattern supports dust extraction when used with Clean Sanding Hookit backup pads
• Lightweight at 0.09 pounds for reduced operator fatigue during extended sanding passes

Compatibility

Designed for use with 5 inch Hookit Clean Sanding discs, 5 inch Hookit Dust Free discs, and 5 inch Hookit discs, and intended for use with a Clean Sanding Hookit backup pad.

Installation Notes

This interface pad is installed between the backup pad and the sanding disc before attaching the disc assembly to the random orbital or orbital sander. Ensure the backup pad and disc are properly seated and aligned before operating the tool. Inspect the foam pad regularly for compression set or tearing, and replace when conformability is noticeably reduced.
