Frequently Asked Questions

Is this accessory compatible with my existing derusting tool?

Yes, these accessories are specifically manufactured as replacement parts for the GG30/54-SP 6 derusting brush. They fit standard pneumatic and electric angle grinders with a 1-inch arbor and M14 thread.

What is the bristle material?

The bristles are made of high-tensile carbon steel, which provides aggressive rust removal and excellent durability on steel surfaces. This material is resistant to breaking and suitable for heavy marine use.

How often should I replace the brush?

Replacement frequency depends on usage intensity and surface condition. Under normal shipyard operations, we recommend inspecting the brush before each shift and replacing it when bristle wear reaches 50% or when performance drops noticeably.

Can this be used on non-ferrous metals?

While designed for steel, it can be used on other metals with caution. However, avoid using it on aluminum or other soft metals, as the aggressive steel bristles may cause scratching or surface damage.
