Abrasive Fibre Disc KLINGSPOR CS561 Ø115 mm 40 grit, pack of 25

The KLINGSPOR CS561 abrasive fibre disc is a 115 mm, 40-grit disc supplied in a pack of 25. Designed for medium-coarse material removal, surface blending and deburring, this abrasive disc is intended for use on both metal and wood. The fibre backing provides stable support for the abrasive layer, ensuring consistent cutting performance and longer life in demanding grinding tasks. The disc fits angle grinders and sanding tools that accept 115 mm discs and is suitable for open-grit stock removal where a balance between aggressiveness and surface finish is required.

Advantages

KLINGSPOR CS561 discs combine a robust fibre backing with a 40-grit abrasive to deliver effective material removal while maintaining disc stability during operation. The consistent abrasive distribution supports uniform wear and predictable results across the pack. Supplied in a convenient pack of 25, the discs reduce downtime for frequent disc changes and are suitable for workshop and onsite applications. The construction minimises loading and helps preserve cutting performance on both ferrous and non-ferrous metals as well as wood.

How to use

Select an appropriate 115 mm sanding attachment and secure the CS561 disc according to the tool manufacturer’s instructions. Start grinding at moderate speed to establish control, increasing pressure and speed as required for material removal while avoiding excessive heat build-up. Hold the grinder at a consistent angle and use smooth, controlled movements to achieve even material removal and a uniform finish. Replace discs when abrasive performance decreases or backing shows signs of excessive wear.

Usage recommendations

Use suitable personal protective equipment including eye, ear and respiratory protection and gloves. Verify tool rpm compatibility with 115 mm discs and observe recommended operating speeds. For best results on metal, clean the surface of loose contaminants before grinding; for wood, test on scrap material to confirm desired finish before working on the main piece.
