3M 7100048736 Psa Abrasive Disc 80 Grit 5 Inch Ceramic

Product Description

The 3M 7100048736 is a pressure-sensitive adhesive (PSA) abrasive disc built for use with random orbital sanders. Part of the 3M 775L Series, this 5-inch disc uses a ceramic abrasive grain rated at 80 grit, placing it in the medium grade. The film backing provides a flexible, durable base that conforms to contoured surfaces and resists tearing under load. The PSA mount allows fast disc changes without the need for a separate hook-and-loop interface. Ceramic grain is self-sharpening, which helps maintain cut rate as the disc wears. No vacuum holes are included in this configuration.

This disc is suited for material removal, surface preparation, and blending tasks on wood, composites, and certain metal substrates. The 775L Series film-backed design is a common choice for finish work where a flatter, more consistent scratch pattern is required. Typical users include finish carpenters, cabinet makers, body shop technicians, and general fabrication trades who run 5-inch random orbital sanders.

Key Features

• Ceramic abrasive grain is self-sharpening for consistent cut rate throughout disc life
• 5-inch diameter fits standard 5-inch random orbital sanders
• 80 grit medium grade suited for stock removal and surface leveling
• Film backing is flexible and tear-resistant for use on contoured surfaces
• PSA mount enables quick disc changes without a hook-and-loop pad
• No vacuum holes — compatible with non-vented backup pads

Compatibility

Designed for use with random orbital sanders accepting 5-inch PSA abrasive discs and non-vented backup pads. Part of the 3M 775L Series.

Installation Notes

Attachment is made by pressing the PSA-backed disc firmly onto a clean, dry backup pad surface. Ensure the backup pad is free of debris or adhesive residue before mounting to achieve full contact. Worn or contaminated backup pads will reduce adhesion and disc performance. Disc should be removed and replaced when cut rate drops noticeably rather than continuing to work a spent disc.
