3M 7010326511 Psa Cloth Disc 16 Inch 40 Grit Ao

Product Description

The 3M 7010326511 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in industrial and trade applications. Built on an X-weight cloth backing, this 16-inch disc runs at 40 grit with an aluminum oxide abrasive that cuts aggressively and holds up over extended use. The PSA backing bonds firmly to a backup pad or steel platen and releases cleanly for fast disc changes, keeping downtime low during production runs. A resin bond system locks the abrasive grain in place and shields the disc from heat buildup, extending usable life on demanding jobs. Licensed tradespeople and shop technicians working metal, wood, or composite surfaces will find this disc suited for both wet and dry sanding operations.

This disc is intended for use with rotary sanding equipment fitted with a compatible 16-inch PSA backup pad or steel platen. It is well suited for surface preparation, weld blending, paint removal, and stock removal tasks in fabrication shops, metal finishing operations, and woodworking environments. The 40-grit cut level targets aggressive material removal rather than fine finishing, making it the right choice for initial stock removal or heavy surface conditioning before moving to finer grits.

Key Features

• PSA backing adheres securely to backup pads or steel platens and releases cleanly for quick replacement
• X-weight cloth backing resists tearing and edge wear under aggressive sanding pressure
• Aluminum oxide abrasive delivers fast cut rates and long service life across a wide range of materials
• Resin bond system protects abrasive grain from heat damage, extending disc life
• Suitable for both wet and dry sanding applications
• 16-inch diameter at 40 grit for heavy stock removal tasks

Compatibility

Designed for use with 16-inch PSA rotary backup pads or steel platens on industrial disc sanders and grinders. Confirm equipment arbor size and platen diameter before installation.

Installation Notes

Power down and de-energize the sanding equipment before mounting or removing any disc. Peel the release liner from the PSA backing and align the disc carefully to the center of the backup pad or platen before pressing into contact to avoid air pockets. Ensure the backup pad surface is clean and free of debris for full adhesive contact. Wet sanding applications require confirmation that the equipment and backup pad are rated for wet use.
