Merit Abrasives 08834172090 Psa Disc 8 in 60 Grit

Product Description

The MERIT ABRASIVES 08834172090 is a pressure-sensitive adhesive (PSA) abrasive disc designed for material removal and surface preparation on a wide range of substrates. The disc measures 8 inches in diameter and features 60-grit aluminum oxide abrasive, delivering medium-grade cutting action suited for stock removal, weld blending, and surface leveling. A flexible cloth backing allows the disc to conform to slightly contoured surfaces while maintaining consistent abrasive contact. The PSA mount provides fast, tool-free disc changes on compatible backup pads, reducing downtime during extended grinding or sanding operations.

This disc is well suited for metalworking, woodworking, and fabrication environments where a durable, fast-cutting 8-inch disc is required. It is commonly used on stationary disc sanders and random orbital machines that accept PSA-style backing. Typical applications include paint and rust removal, weld seam preparation, and rough stock removal on steel, wood, and composite materials. The disc ships individually and is appropriate for shop use in manufacturing, auto body, and general fabrication settings.

Key Features

• 8-inch diameter fits standard PSA backup pads without trimming
• 60-grit aluminum oxide provides medium-grade cutting for efficient stock removal
• Flexible cloth backing conforms to surface variations and resists tearing
• Pressure-sensitive adhesive mount allows fast disc swaps with no hardware
• No vacuum holes — suited for machines without dust extraction ports
• Black disc color aids visual wear monitoring during use

Compatibility

Designed for use with stationary disc sanders and power tools that accept 8-inch PSA-mount abrasive discs with a smooth, flat backup pad surface.

Installation Notes

Power down and disconnect the sander or grinding machine before mounting or removing the disc. Clean the backup pad surface of any adhesive residue or debris before applying the new disc to ensure full, even adhesion. Press the disc firmly onto the backup pad from the center outward to eliminate air pockets. Worn or glazed discs should be replaced promptly to maintain consistent material removal rates and prevent workpiece damage.
