Bosch N377 Grinding disc

The Bosch Grinding disc N377 is a cleaning disc with an X-LOCK attachment designed for efficient material removal on metal and masonry surfaces. Its silicon carbide fleece coating continually renews itself to create sharp cutting edges, enabling consistent removal of rust, paint and oxide layers from metal as well as lime deposits and graffiti from stone, marble and concrete. The disc is supported by a fibreglass carrier plate for stability during operation and fits X-LOCK systems for quick, tool-free changes.

Advantages

The silicon carbide fleece coating renews its structure during use, producing sharp cutting edges for steady material extraction. The fibreglass carrier plate provides support and durability under load, while the keyless X-LOCK system enables fast and convenient disc changes. The design is suitable for repeated use on different substrates without frequent loss of cutting performance.

Suitable for

• Removing rust and oxide layers from steel and stainless steel
• Stripping paint from metal surfaces
• Cleaning lime deposits and graffiti from stone, marble and concrete
• Surface preparation before welding or painting

How to use

Secure the Bosch Grinding disc N377 to a compatible X-LOCK angle grinder according to the tool manufacturer’s instructions. Start the grinder at low speed and apply steady, even pressure while moving the disc across the work surface to avoid gouging. Let the coating renew itself during use; increase speed or pressure only as needed for heavier deposits. After use, inspect the disc and replace if the fleece is worn or damaged.

Recommendations

Use appropriate personal protective equipment including eye protection, gloves and a dust mask. Ensure the grinder’s speed rating matches the disc specifications and follow the angle grinder manufacturer’s safety instructions. Avoid excessive pressure and prolonged contact in one spot to prevent surface damage.
