Klingspor 204095 CS 561 Zirconia Alumina Fiber Disc, 125 mm x 22.23 mm, Grit 60, 25-Pack

The Klingspor 204095 fiber disc from the CS 561 series stands apart through its aggressive zirconia alumina abrasive and a reinforced vulcanized fiber backing that holds up under heavy stock removal. Where standard discs glaze or shed grit, this 125 mm disc keeps cutting on steel, stainless steel, and non-ferrous metals, making it a dependable choice for welders, fabricators, and metalworking shops that need consistent performance in a 25-piece pack.

Highlights

• Zirconia alumina abrasive with self-sharpening fracture properties for high material removal.
• Vulcanized fiber backing engineered for tear resistance and cool grinding on angle grinders.
• 22.23 mm bore fits standard 125 mm angle grinders without adapter rings.
• Grit 60 balances fast stock removal with a workable surface finish.
• Rated for 12,200 RPM and 80 m/s, meeting EN 13743 safety requirements.

In daily use

Mount the disc on a 125 mm angle grinder and apply moderate pressure at a low working angle. The synthetic resin bond releases dulled abrasive grains steadily, exposing fresh cutting edges and preventing heat build-up that can blue stainless steel. On mild steel, the disc removes weld beads and mill scale quickly; on stainless, it leaves a uniform scratch pattern ready for finishing; on aluminium and other non-ferrous metals, it resists loading when used with a suitable grinding aid. The 25-piece pack keeps a fresh disc within reach during long fabrication runs.
