After trying this industrial-grade brush, I was impressed with the results. It's perfect for tackling grime and rust on heavy machinery. The bristles are sturdy and the shank is well-crimped, making for a durable tool. However, the brush may be a bit too harsh for some surfaces, so be mindful of that. Overall, I would recommend this brush for anyone in need of a heavy-duty abrasive tool in the Industrial and Scientific field.
