Key Features of Bosch Professional Flap Discs

• Zirconia alumina and semi-friable aluminium oxide grit: the X551 blend gives a high removal rate and long life on metal, so you get through more work per disc.
• X-cloth backing: a robust, stable backing keeps performance steady on tough surfaces and helps the disc stand up to hard use.
• Fully synthetic resin bonding: grit is bonded to the X-cloth for consistent sanding behaviour from start to finish.
• Straight and angled flap discs: straight discs suit edge work and flat surfaces, while angled discs are better for aggressive grinding and weld preparation.
• X-LOCK compatibility: X-LOCK discs fit compatible grinders without a spanner or lock nut, which speeds up disc changes on site.
• Dedicated Inox option: the X581 is made for stainless steel, helping you achieve a clean finish on the material.

Frequently Asked Questions

Which Bosch Professional flap disc is best for general metal grinding?

The EXPERT X551 for Metal is a strong all-rounder for deburring and grinding on metal. For tougher, more demanding work, step up to the PRO X571 Best for Metal or the zirconium abrasive discs.

Can I use Bosch Professional Flap Discs on stainless steel?

Yes. The X581 Best for Inox is designed for stainless steel. Use a disc intended for stainless only on stainless, and avoid discs previously used on other metals to prevent contamination.

What is the difference between straight and angled flap discs?

Straight (flat) discs give better control and are suited to edges and finishing. Angled discs have a conical profile that removes material faster, making them well suited to weld grinding and heavier stock removal. Always wear suitable PPE, fit the correct guard and follow HSE and COSHH guidance on dust.
