Norton 66254406395 Deburring Disc 3 in Medium Aluminum Oxide

Product Description

The NORTON 66254406395 is an aluminum oxide deburring disc designed for quick-change mounting systems. At 3 inches in diameter and 0.25 inches thick, this medium-grade disc handles edge deburring, surface blending, and light stock removal on metal workpieces. The aluminum oxide abrasive delivers consistent cut rate and durability across a range of ferrous and non-ferrous metals. A density rating of 7 to 9 provides an open, flexible structure that conforms to contours while resisting loading. Fabricators, maintenance technicians, and metalworking professionals reach for this disc for fast, clean deburring work on grinders and die grinders equipped with a compatible quick-change arbor.

This deburring disc is suited for use in metal fabrication shops, maintenance and repair operations, and light manufacturing environments. It is commonly used on steel, stainless steel, and aluminum to remove burrs from drilled, punched, or cut edges and to blend weld seams or surface irregularities. The quick-change connector allows rapid disc swaps without additional tools, reducing downtime during production or service work. It is a practical single-piece consumable for both bench grinder setups and handheld right-angle die grinder applications.

Installation Notes

Installation and disc changes should be performed by a qualified technician with the grinder powered off and unplugged or air supply disconnected before mounting or removing the disc. Verify that the grinder spindle speed rating meets or exceeds the disc maximum rated speed before use. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of wear through to the backing. Always use appropriate personal protective equipment including eye and face protection when operating abrasive discs.
