Merit Abrasives 08834173018 Psa Sanding Disc 10 in 50 Grit

Product Description

The MERIT ABRASIVES 08834173018 is a 10-inch pressure-sensitive adhesive (PSA) sanding disc designed for use on stationary disc sanders. It features a 50-grit aluminum oxide abrasive on a flexible cloth backing, placing it in the coarse grade range. This disc is built for aggressive material removal on wood, metal, and composite surfaces. The cloth backing provides durability and flexibility under the heat and pressure generated during extended sanding runs. It is part of the PSAAO series and is a standard single-disc unit suitable for professional shop environments and trade applications.

This disc is sized for stationary disc sanders that accept 10-inch PSA-mount abrasives. The coarse 50-grit rating makes it well-suited for rapid stock removal, surface leveling, and preparation work ahead of finer finishing passes. Woodworking shops, metal fabricators, and general tradespeople working with stationary sanders will find this disc a practical consumable for high-material-removal tasks. No vacuum holes are included, making it a solid-face disc appropriate for sanders without dust extraction ports at the platen.

Key Features

• 10-inch diameter fits stationary disc sanders with PSA platen mounting

• Flexible cloth backing withstands heat and pressure in demanding sanding applications

Compatibility

Designed for use with stationary disc sanders that accept 10-inch PSA (pressure-sensitive adhesive) abrasive discs with a solid, non-perforated face.

Installation Notes

PSA sanding discs are installed by peeling the liner from the adhesive backing and pressing firmly onto a clean, dry sanding platen. Ensure the sander is powered off and unplugged before mounting or removing any abrasive disc. Smooth out any air bubbles from the center outward to ensure full contact and prevent premature disc failure during operation. Replace the disc when abrasive cutting action noticeably decreases or when the backing shows signs of separation.
