Sanding Discs Bosch X551 Expert for Metal 1 pc

The Bosch X551 Expert for Metal sanding disc is designed for efficient material removal on metal surfaces. Its abrasive blend of zirconia alumina and semi-friable aluminium oxide provides high removal rates and a long service life when working with carbon steel, mild steel, aluminium, non-ferrous metals and cast iron. The abrasive is bonded with fully synthetic resin to an X-cloth backed disc for consistent sanding behaviour and increased durability. The disc is compatible with angle grinders and is available in angled or straight versions mounted on fibreglass or plastic carrier plates.

Advantages

The combination of zirconia alumina and semi-friable aluminium oxide grit gives a balance of aggressive cutting and controlled wear, delivering both effective stock removal and extended lifetime. The robust X-cloth backing with stable support maintains performance on demanding surfaces and under higher loads. Fully synthetic resin bonding ensures steady abrasive action and reliable behaviour during prolonged use. Compatibility with angle grinders and availability in different carrier plate options increase versatility for various metalworking tasks.

How to use

Fit the sanding disc to a compatible angle grinder following the grinder manufacturer's instructions and ensure the disc type and size match the tool. Securely fasten the carrier plate if supplied and check that the disc is undamaged before use. Operate the grinder at the recommended speed range for the disc and apply steady, even pressure while moving across the metal surface to avoid overheating or gouging. Replace the disc when abrasive performance decreases or damage is visible.

Recommendations

Use personal protective equipment such as goggles, gloves and hearing protection when working with angle grinders. Test on a small area first to determine the optimal speed and pressure for the specific metal. For best results on welds and heavy stock removal, start with coarser grits and progress to finer grits as needed.
