Norton 66623325936 Hook Loop Disc Aluminum Oxide Very Fine

Product Description

The NORTON 66623325936 is a non-woven hook and loop abrasive disc designed for surface finishing, blending, and light material removal on metal, wood, and composite surfaces. Built with aluminum oxide abrasive material in a very fine grade, this 4.5-inch disc mounts quickly to any compatible hook and loop backing pad. The flexible, non-woven construction conforms to contoured surfaces, making it a practical choice for deburring, cleaning, and final finish work. Weighing just 0.05 pounds, it is lightweight and easy to handle during extended use. Tradespeople including fabricators, HVAC technicians, pipefitters, and general contractors rely on this disc type for consistent surface prep results.

This disc is suited for residential and commercial applications where controlled surface finishing is required. Common use cases include weld blending on sheet metal, surface prep before coating or painting, and light oxide or scale removal on pipe and structural components. The very fine grade makes it appropriate for finishing passes rather than aggressive stock removal. It is sold individually and is well matched to angle grinders and random orbital tools equipped with hook and loop backing pads measuring 4.5 inches.

Installation Notes

Installation and disc changes should be performed with the tool powered off and unplugged or the battery removed. Align the disc squarely onto the hook and loop backing pad and press firmly to ensure full engagement before operating. Inspect the disc for tears or excessive wear before each use and replace if the abrasive surface is compromised. Follow applicable ANSI and tool manufacturer guidelines for maximum RPM ratings when selecting a backing pad.
