3M 7000119557 Psa Disc 240 Grit 6 Inches 100 Pack

Product Description

The 3M 7000119557 is a pressure-sensitive adhesive (PSA) abrasive disc designed for power sanding applications in metal fabrication, woodworking, and surface prep work. This disc measures 6 inches in diameter, carries a 240 grit rating in the very fine grade range, and uses aluminum oxide as the cutting mineral. The C-weight paper backing delivers a balance of flexibility and support, making it well suited for contour sanding and finish work. Each disc mounts quickly to a PSA-compatible backup pad without hardware. The series 236U construction is rated up to 12,000 RPM. Sold in a box of 100 discs.

These discs are used in light material removal, blending, and final-stage surface preparation on wood, metal, and painted surfaces. The gold-colored, flexible paper backing conforms to mild curves, making them a practical choice for cabinet shops, auto body prep, and general metal finishing. No vacuum holes are present, so they are intended for solid backup pads rather than random orbital sanders with dust-extraction ports. Machinists, fabricators, woodworkers, and finishing technicians are the primary installers and users of this consumable abrasive.

Key Features

• 240 grit aluminum oxide abrasive for very fine material removal and surface blending
• PSA mounting system for fast, tool-free disc changes on compatible backup pads
• C-weight paper backing provides flexibility for contoured and flat surface work
• Rated to 12,000 RPM for use with standard right-angle and orbital disc sanders
• No vacuum holes — designed for solid or non-perforated backup pads
• Pack of 100 discs reduces changeout downtime on high-volume jobs

Compatibility

Designed for use with PSA (pressure-sensitive adhesive) backup pads accepting 6-inch abrasive discs. No vacuum holes are present, so this disc is not compatible with dust-extraction backup pads.

Installation Notes

Power down or unplug the sander before mounting or removing a disc. Confirm the backup pad is clean and free of adhesive residue before applying a new disc to ensure full adhesive contact. Do not exceed the 12,000 RPM maximum speed rating. Dispose of worn discs promptly — a disc that has lost its adhesive bond mid-operation can become a hazard.
