Norton 66623338571 Hook Loop Disc 80 Grit 1.5 Inch

Product Description

The NORTON 66623338571 is a hook and loop abrasive disc designed for surface preparation, light deburring, and finishing work on metal and similar substrates. Built with aluminum oxide abrasive bonded to a flexible non-woven backing, the disc delivers consistent medium-grade cutting action at 80 grit. At 1.5 inches in diameter, it fits compact die grinders and right-angle tools used daily by HVAC technicians, plumbers, and pipefitters for cleaning pipe ends, removing mill scale, and prepping mating surfaces before fitting or brazing. The flexible non-woven construction conforms to contoured workpieces, reducing gouging on softer metals.

This disc is suited for light-duty metal finishing tasks in residential and commercial trade environments. Typical applications include pipe end prep, weld-area cleanup, and surface conditioning on copper, steel, and aluminum. The hook and loop attachment system allows fast disc changes without tools, which improves productivity during repetitive prep work on fittings and valve bodies. Its compact 1.5-inch size reaches into tight clearances that larger grinding discs cannot access.

Key Features

• 80 grit aluminum oxide abrasive for medium-grade material removal and surface conditioning

Compatibility

Designed for use with hook and loop-compatible die grinders and rotary tools accepting 1.5-inch abrasive discs rated for speeds up to 30,000 RPM.

Installation Notes

Installation and disc changes should be performed with the tool unplugged or the air supply disconnected. Verify that the tool spindle speed does not exceed the 30,000 RPM disc rating before use. Press the disc firmly onto the hook and loop pad to ensure full contact before starting the tool. Eye protection and gloves are standard PPE for any grinding or surface prep operation.
