Merit Abrasives 08834172046 Psa Disc 40 Grit 6 in

Product Description

The MERIT ABRASIVES 08834172046 is a 6-inch pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on metal, wood, and composite surfaces. Built with aluminum oxide abrasive on a flexible cloth backing, this disc delivers consistent cutting action and durability under high-friction conditions. The 40-grit rating places it in the coarse cutting range, making it well suited for rapid stock removal, weld blending, and surface prep work. The PSA mounting system allows quick, secure attachment to compatible backup pads without fasteners or clips.

This disc is used in industrial and trade finishing applications where aggressive surface preparation is required. It is commonly used in fabrication shops, HVAC sheet metal work, plumbing rough-in prep, and general metalworking environments. The flexible cloth backing conforms to slightly contoured surfaces, making it usable on both flat and mildly curved workpieces. The disc does not include vacuum holes, so it is intended for use with solid, non-perforated backup pads.

Key Features

• 40-grit aluminum oxide abrasive for fast, aggressive stock removal
• Flexible cloth backing conforms to flat and mildly curved surfaces
• Pressure-sensitive adhesive (PSA) mount attaches directly to compatible backup pads
• 6-inch diameter fits standard PSA backup pads of the same size
• No vacuum holes — designed for solid backup pad use
• Black disc color for easy visual identification on the work surface

Compatibility

Designed for use with standard 6-inch PSA (adhesive-mount) backup pads on angle grinders, disc sanders, and similar rotary finishing tools that accept PSA-style abrasive discs without vacuum ports.

Installation Notes

Ensure the backup pad surface is clean and free of debris before applying the PSA disc — contaminants under the adhesive layer reduce holding strength and can cause disc slippage during use. Align the disc carefully before pressing it onto the backup pad, as the adhesive bonds quickly and repositioning degrades the adhesive. Inspect the disc before each use and replace immediately if tears, excessive wear, or delamination are observed. Operate at or below the disc's rated RPM as marked on the tool or backup pad.
