RYOBI 115mm Grinding Disc Set, 6-Piece, Aluminium Oxide, 22.23mm Bore, 80 m/s, EN 12413

Grinding metal by hand is slow, inconsistent, and hard on your tools. The RYOBI 115mm Grinding Disc Set gives you six professional-grade discs that cut through steel, stainless steel, and cast iron with controlled aggression. Each disc uses sharp aluminium oxide abrasive bonded in a resinoid matrix, so you get fast stock removal without premature wear. The 6mm thickness and 22.23mm bore fit standard 115mm angle grinders, and the 80 m/s rating means you can run them at full speed with confidence. From deburring rough edges to prepping welds, this set keeps your grinder working and your results clean.

Metal fabricators, welders, maintenance technicians, and serious DIYers who need a dependable supply of grinding discs for everyday tasks.

Tips

Always inspect discs for cracks or damage before mounting. Use the correct flange and tighten securely, but do not overtighten. Let the disc reach full speed before contacting the workpiece, and apply steady, even pressure—let the abrasive do the work. Store discs flat in a dry place to prevent warping. Replace any disc that shows signs of glazing, loading, or excessive wear.
