Merit Abrasives 66623325929 Hook Loop Disc 150 Grit 2 in

Product Description

The MERIT ABRASIVES 66623325929 is a 2-inch hook-and-loop abrasive disc designed for fine surface preparation and finishing work. Built with a non-woven aluminum oxide construction, it delivers consistent cut and finish at a Very Fine 150-grit rating. The flexible backing conforms to contoured surfaces, making it well-suited for blending, scuffing, and light material removal on a range of substrates. Rated to 30,000 RPM, it is compatible with standard hook-and-loop random orbital and disc sanders used by trade professionals in HVAC fabrication, plumbing prep, and general metalworking or finishing applications.

This disc is used in light-duty surface finishing scenarios where controlled abrasion is needed without aggressive stock removal. The non-woven abrasive matrix resists loading and maintains cutting action longer than coated abrasives in comparable grit ranges. It is appropriate for use on metal, painted surfaces, and composite materials in residential and commercial service environments. No vacuum holes are included, so it is intended for use with solid-backing pad systems rather than dust-extraction hook-and-loop sanders.

Key Features

• 150-grit Very Fine grade for controlled surface finishing and blending
• Non-woven aluminum oxide construction resists loading and extends disc life
• Flexible backing conforms to curved and contoured work surfaces
• Hook-and-loop attachment for quick disc changes on compatible sanders
• Maximum rated speed of 30,000 RPM for compatibility with high-speed rotary tools
• Blue disc color for easy grit identification during shop or field use

Compatibility

Designed as an OEM-style replacement or consumable abrasive disc for hook-and-loop random orbital sanders and rotary disc sanders accepting 2-inch solid backing pads. No vacuum-hole disc slots are present; use with non-perforated backing pads only.

Installation Notes

Installation requires a hook-and-loop backing pad matched to a 2-inch diameter disc. Ensure the sander or rotary tool is powered off and unplugged before attaching or removing the disc. Do not exceed the 30,000 RPM maximum rated speed. Inspect the disc for tears or delamination before each use and discard any disc showing visible damage.
