Cutting/Grinding Fiber Disc Bosch X-LOCK 125 mm K36 for angle grinders

Bosch Best for Metal R574 X-LOCK 125 mm abrasive fibre disc with K36 grit is designed for aggressive material removal on metal. The disc fits angle grinders with the X-LOCK quick-change system and is intended for tasks such as surface preparation, deburring and rapid stock removal. It features a 22.23 mm arbor hole and a construction aimed at long life during grinding and polishing operations.

Advantages

The X-LOCK mounting allows tool-free, quick and secure disc changes. Coarse K36 grit provides fast cutting and effective removal of rust, weld spatter and paint. The 125 mm diameter offers a balance between reach and control, while the 22.23 mm bore ensures compatibility with standard X-LOCK angle grinders. Construction optimised for long life reduces the need for frequent disc replacement during intensive metalworking.

Suitable for

• Removing rust and old paint from metal surfaces

How to use

Mount the disc on an X-LOCK compatible angle grinder following the tool manufacturer’s safety instructions: ensure the grinder is switched off and unplugged (or battery removed) before fitting. Engage the X-LOCK mechanism until the disc locks in place. Hold the grinder firmly with both hands, start the tool and allow it to reach full speed before applying to the workpiece. Use steady, even pressure and move the disc across the metal surface to remove material. Replace the disc when wear reduces cutting performance or if damage is visible.

Usage recommendations

Use appropriate personal protective equipment: safety glasses or face shield, gloves, hearing protection and a dust mask. Select K36 for fast material removal; for finer finishing or less aggressive work choose a higher grit. Check compatibility with your grinder’s speed rating and follow Bosch and tool-maker guidelines for safe use and maximum service life.
