3M 7000118333 Aluminum Oxide Shop Roll 100 Grit

Product Description

The 3M 7000118333 is an aluminum oxide abrasive shop roll intended for hand sanding, machine sanding, and general stock removal in metalworking, woodworking, and finishing applications. The roll measures 1.5 inches wide by 50 yards long, providing a substantial working supply that can be cut to any length as the job requires. The abrasive is rated at 100 grit, placing it in the fine grade range — aggressive enough to remove surface irregularities and light scale, yet controlled enough for intermediate finishing passes. A J-weight cloth backing delivers the flexibility needed to conform to contoured surfaces while holding up to repeated flexing and tearing without delaminating.

This shop roll is suited for use in fabrication shops, maintenance facilities, and production environments where consistent abrasive performance across varied tasks is required. Typical applications include deburring metal edges, blending weld seams, sanding wood components between coats, and surface preparation before painting or coating. The roll format lets technicians tear off exactly the length needed, reducing waste and keeping the work area organized. It is equally at home as a handheld strip or loaded onto a file board or mandrel-style holder.

Key Features

• 100 grit aluminum oxide abrasive for fine-grade material removal and surface blending
• 1.5-inch width works with standard shop roll holders and narrow-profile sanding applications
• 50-yard length provides extended working supply from a single roll
• J-weight cloth backing offers flexibility for contoured and curved surface work
• Tear-to-length format eliminates the need for scissors or cutting tools at the bench

Compatibility

Designed as a general-purpose abrasive shop roll compatible with standard 1.5-inch roll holders, file boards, and hand-sanding applications across metalworking and woodworking environments.

Installation Notes

No power disconnect is required for hand-use applications; when loading onto a powered sanding mandrel or roll holder, shut down and de-energize the equipment before threading the abrasive. Inspect the roll for tears or delamination before each use and discard sections that show backing separation. Use appropriate respiratory protection and eye protection when sanding, particularly on metals that generate fine particulate.
