Merit Abrasives 08834162550 Hook Loop Disc 150 Grit

Product Description

The MERIT ABRASIVES 08834162550 is a 4.5-inch non-woven hook and loop abrasive disc designed for surface preparation, blending, and finishing applications. Built with aluminum oxide abrasive material at 150 grit, it falls in the very fine grade range, making it well suited for light material removal, scuff sanding, and surface conditioning without heavy stock removal. The hook and loop backing allows for quick disc changes on compatible random orbital and angle head tools. At 0.034 pounds per disc, it is lightweight and flexible, conforming to contoured and irregular surfaces. Licensed tradespeople and professional finishing contractors rely on this type of disc for consistent, repeatable results across metal, wood, and composite substrates.

This disc is intended for use on angle grinders, random orbital sanders, and finishing tools equipped with hook and loop backup pads. The very fine 150 grit rating makes it appropriate for pre-paint scuffing, weld blending, and inter-coat sanding in both residential and light commercial settings. It is flexible by design, allowing it to follow curved or profiled workpieces without bridging. No vacuum holes are present, so it is paired with standard solid backup pads rather than dust-extraction systems. Maximum operating speed is rated at 13,000 RPM, which fits the operating range of most standard-duty angle grinders and finishing sanders in trade environments.

Key Features

• 150 grit, very fine grade aluminum oxide abrasive for light stock removal and surface conditioning
• Non-woven construction provides flexibility to conform to contoured and irregular surfaces
• Hook and loop backing enables fast, tool-free disc changes on compatible backup pads
• Rated to 13,000 RPM maximum operating speed
• No vacuum holes — compatible with standard solid hook and loop backup pads
• Blue disc color for quick visual grit identification in multi-grit workflows

Compatibility

Designed for use with hook and loop backup pads on 4.5-inch random orbital sanders and angle grinders. Compatible with standard solid backup pads rated for non-woven discs at or below 13,000 RPM. No vacuum hole configuration is required.

Installation Notes

This disc is installed and removed by hand — no tools required due to the hook and loop attachment system. Confirm the backup pad diameter matches the 4.5-inch disc diameter before use. Do not exceed the 13,000 RPM maximum speed rating; verify the tool nameplate RPM before mounting. Inspect the disc and backup pad for wear or damage before each use, and replace if the abrasive surface is glazed, loaded, or backing integrity is compromised.
