Klingspor 65698 CS 561 Zirconia Alumina Fibre Disc 115 mm Grit 36, 25-Pack

Built for aggressive stock removal at 80 m/s, the Klingspor 65698 fibre disc pairs zirconia alumina grit with a vulcanized fibre backing to power through steel, stainless, and non-ferrous metals. Each 115 mm disc spins safely up to 13,300 RPM on a standard angle grinder, making fast work of weld seams, deburring, and rust removal.

Overview

The CS 561 series is engineered for professional metalworking where speed and durability matter. The 36-grit zirconia alumina abrasive self-sharpens under heat and pressure, maintaining a consistent cut rate over the life of the disc. A 22.23 mm bore fits the most common angle grinder spindles, and the resin bonding system keeps the abrasive firmly attached even under heavy side loads.

What stands out

• Zirconia alumina abrasive delivers up to 3x longer life than standard aluminium oxide on stainless steel.
• Vulcanized fibre backing provides a rigid yet conformable platform for high-pressure grinding.
• 80 m/s maximum operating speed ensures compatibility with high-RPM angle grinders.
• 25-disc pack keeps production running with fewer changeovers.
• EN 13743 safety certification means every disc meets strict European standards for bonded abrasives.
