Norton 666233-57282 Aluminum Oxide Fiber Disc 120 Grit 25 Pack

Product Description

The NORTON 666233-57282 is an aluminum oxide fiber disc designed for aggressive material removal on metal, welds, and surface preparation applications. Measuring 5 inches in diameter with a 7/8-inch arbor hole, this disc fits standard angle grinders and disc sanders used throughout fabrication and finishing trades. The 120-grit aluminum oxide abrasive provides a medium-fine cut suitable for blending welds, deburring, and light stock removal without excessive heat buildup. Sold in a package of 25 discs, this product is suited for shop environments where consistent abrasive performance and volume supply matter.

This fiber disc is intended for use in metal fabrication shops, welding operations, and general industrial surface preparation. It is appropriate for ferrous and non-ferrous metals where controlled material removal and surface finish are required. The Merit FX370 designation identifies the abrasive product line this disc belongs to. Metalworkers, fabricators, and maintenance technicians are the typical end users in both shop and field settings.
