Arc Abrasives 31466 Surface Conditioning Disc 3 in 80 Grit

Product Description

The ARC ABRASIVES 31466 is a 3-inch Type S surface conditioning disc engineered for edge grinding and surface prep work on metal. It combines an extremely flexible backing with a 100 percent cotton abrasive construction, which allows the disc to conform to contours and edges without loading or gouging the workpiece. At 80 grit, it removes light scale, oxidation, and surface irregularities while leaving a consistent scratch pattern. Fabricators, welders, and metal finishing technicians use this disc for controlled material removal on flat and shaped workpieces.

This disc is well suited for edge grinding applications on cold rolled mild steel and stainless steel sheet. The flexible backing makes it particularly effective where rigid abrasives would leave chatter marks or uneven finishes. It is a common choice in fabrication shops and field metalwork where surface condition and cleanliness matter before welding, coating, or inspection. The Type S attachment style provides quick mounting and removal on compatible grinders and mandrels.
