3M 7000042724 Hookit Half Round Sanding Pad 6 in

Product Description

The 3M 7000042724 is a half round sanding pad designed for use with 6-inch Hookit hook-and-loop abrasive discs. The pad features a 0.25-inch radius edge that allows the wrapped disc to reach tight corners, coves, and contoured surfaces that flat pads cannot access. Constructed from medium density foam, the pad conforms to irregular workpiece profiles without losing control of the abrasive. It is sized for standard 6-inch Hookit disc systems and is suited for body shop technicians, finish carpenters, and trade professionals performing surface preparation in confined areas.

This pad is intended for hand sanding applications where a conventional flat backing pad would bridge over recesses or fail to follow surface contours. Typical use cases include sanding inside molding profiles, door jamb corners, curved body panels, and similar hard-to-reach areas. The half round shape positions the disc edge precisely so the abrasive contacts the work surface at the correct angle, reducing the risk of uneven material removal in detailed or shaped surfaces.

Key Features

• Half round profile with a 0.25-inch radius edge for sanding in hard-to-reach areas
• Compatible with 6-inch diameter Hookit hook-and-loop abrasive discs
• Medium density foam construction conforms to curved and irregular surfaces
• Lightweight at 0.08 pounds for reduced hand fatigue during extended use
• Sold individually — use with existing Hookit disc inventory

Compatibility

Designed for use with 6-inch diameter Hookit hook-and-loop abrasive discs. Confirm disc diameter and attachment system before ordering.

Installation Notes

No power tools or fasteners are required — the disc attaches to the pad via the Hookit hook-and-loop interface. Wrap the abrasive disc fully around the pad before use to ensure the disc edge is seated against the radius. Inspect the pad foam for tears or compression set that could reduce conformability before each use session. This pad is intended for hand sanding only and should not be mounted to a powered orbital or random-orbital tool.
