Bosch X-LOCK R444 EXPERT FOR METAL Sanding disc

The Bosch X-LOCK R444 EXPERT FOR METAL sanding disc is designed for finishing and smoothing steel and other metal surfaces. The aluminium oxide abrasive and fully synthetic resin bonding on a vulcanised fibre backing deliver stable performance and consistent sanding results. The disc features a flat centre and is supplied as a single unit, compatible with both X-LOCK and standard rubber backing pads.

Advantages

Aluminium oxide grain is optimised for metal applications, providing effective material removal and good surface quality. The fully synthetic resin bond on a vulcanised fibre backing ensures high work stability and prolonged life under load. The keyless X-LOCK mounting enables quick, tool-free disc changes and the disc also fits standard angle grinders when used with an appropriate backing pad.

How to use

Attach the disc to a compatible angle grinder using the X-LOCK system or clamp it to a standard rubber backing pad. Ensure the grinder is disconnected from power when fitting the disc. Run the grinder at the manufacturer-recommended speed for the disc and apply steady, even pressure while sanding. Do not overload the disc; allow the abrasive to do the work. Replace the disc if it becomes clogged, worn or damaged.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves, hearing protection and dust mask). Match disc size and maximum RPM rating to your angle grinder. For best results on stainless or hardened steels, confirm material compatibility and test on a small area first.
