Dynabrade 93801 Sanding Sheet 100 Grit Aluminum Oxide

Product Description

The DYNABRADE 93801 is an aluminum oxide sanding sheet designed for dry abrasive material removal on flat and contoured surfaces. Measuring 7 inches long by 3.67 inches wide, it accepts 100 grit abrasive — a medium grit suited for stock removal, surface leveling, and preparation before finish sanding. Aluminum oxide is a durable, self-fracturing abrasive grain that maintains a sharp cutting edge through the stroke, making it a reliable choice for wood, metal, plastic, and composite surfaces in production or maintenance environments. Licensed tradespeople and finishing technicians use sheets like this in both shop and field applications.

This sanding sheet is used in dry sanding applications across woodworking, metal fabrication, auto body preparation, and general surface finishing. At 100 grit, it is appropriate for intermediate surface preparation — aggressive enough to remove mill scale, old coatings, or rough tooling marks, while leaving a surface ready for finer finishing steps. It is sized for use with compatible orbital, palm, or straight-line sanders that accept sheets of this dimension.

Key Features

• 100 grit aluminum oxide abrasive for medium-duty material removal and surface prep
• Dry-use construction — not rated for wet or lubricated sanding
• Sheet dimensions of 7 inches by 3.67 inches fit compatible pad sanders
• Self-fracturing aluminum oxide grain maintains cutting efficiency across the sheet life
• Lightweight at 0.05 pounds per sheet, minimizing added mass on orbital tools

Compatibility

Designed as an OEM-style replacement sanding sheet for use with pad sanders and finishing tools that accept sheets measuring 7 inches by 3.67 inches.

Installation Notes

Installation of sanding sheets is performed by machinists, finishers, woodworkers, and maintenance technicians. Before changing sheets, power down and disconnect the sander from its air supply or electrical source. Confirm the replacement sheet is properly seated and secured to the pad before resuming operation. Always wear appropriate eye protection and respiratory protection when dry sanding.
