3M 7100192406 Psa Cloth Sanding Disc 4.75 in P150 Grit Ao

Product Description

The 3M 7100192406 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal on a variety of surfaces. The disc uses an aluminum oxide abrasive bonded with a resin system that resists heat buildup, extending disc life during aggressive grinding and finishing operations. An X-weight cloth backing provides the durability needed for demanding applications without tearing or edge wear. At 4.75 inches in diameter and P150 grit, this disc suits intermediate finishing stages where controlled stock removal and surface prep are the priority. Licensed tradespeople and fabricators working metal, wood, or composite surfaces will find it suited to both wet and dry use.

This disc is intended for use on backup pads or steel platens compatible with PSA-mount disc tools. The pressure-sensitive adhesive backing allows fast mounting and clean removal, making disc changes efficient during production or service work. Typical applications include weld blending, surface conditioning, and paint or coating prep in metal fabrication shops, woodworking operations, and general maintenance environments. The 4.75-inch diameter fits standard disc grinders and finishing tools configured for that size.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads or steel platens and releases cleanly for quick disc changes
• X-weight cloth backing resists tearing and edge wear under aggressive material removal loads
• Aluminum oxide abrasive provides fast cutting action and long service life across metal, wood, and composite surfaces
• Resin bond system protects against heat damage to extend disc life
• Suitable for both wet and dry sanding applications

Compatibility

Designed for use with PSA-compatible backup pads and steel platens on disc grinders and finishing tools that accept 4.75-inch diameter PSA sanding discs.

Installation Notes

Disc mounting and removal should be performed with the tool powered off and disconnected from its power source. Ensure the backup pad or steel platen surface is clean and free of adhesive residue before mounting a new disc to achieve full adhesion. Worn or damaged backup pads should be replaced prior to mounting to avoid uneven disc contact. Always wear appropriate PPE including eye protection and gloves when operating grinding and finishing equipment.
