Sanding Discs Bosch X551 Expert for Metal 2608607347 125mm 60-120 Grit

Bosch X551 Expert for Metal sanding discs (125 mm, 60–120 grit) are engineered for efficient material removal and consistent performance on metal surfaces. The blended abrasive of zirconia alumina and semi-friable aluminium oxide provides a high removal rate and long life. A durable X-cloth backing bonded with fully synthetic resin ensures stable sanding behaviour and resistance on tough substrates. These discs are intended for deburring, weld preparation and removal of discoloration, stock and surface imperfections on carbon steel, mild steel, aluminium, non‑ferrous metals and cast iron. They are compatible with angle grinders and come in angled or straight versions mounted on fibreglass or plastic carrier plates.

Advantages

The X551 Expert for Metal delivers efficient stock removal with sustained cutting performance, combining good lifetime and consistent results. Its zirconia alumina and aluminium oxide grit mix offers balance between aggressiveness and durability, while the robust X-cloth backing and synthetic resin bond maintain stable contact and reduced tearing during heavy use. Compatibility with standard angle grinders and availability in different carrier plate types increase application flexibility.

• Deburring metal edges after cutting or machining
• Preparing weld seams and removing welding spatter
• Removing rust, discoloration and surface imperfections
• Shaping and stock removal on carbon steel, mild steel and cast iron

How to use

Mount the sanding disc securely on a compatible 125 mm angle grinder following the tool manufacturer’s mounting instructions. Start with a coarser grit (e.g., 60) for heavy stock removal and progress to finer grits (up to 120) for smoother surface finish. Hold the grinder with steady pressure and move across the workpiece to avoid concentrating heat and creating gouges. Allow the abrasive to do the cutting—avoid excessive force that can reduce disc life or overload the tool.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves, hearing protection and a dust mask). Match grit selection to the task: coarser grits for rapid material removal, finer grits for finishing. Replace discs that show significant wear, tearing or glazing. Ensure the carrier plate type (fibreglass or plastic, angled or straight) suits the angle and accessibility of the work area.
