"The speed rating is OK for my 4.5" angle grinder. I removed the grinders guard plate to give better access in corners etc. It worked well descaling a 35 year old axle assembly before applying fresh rust protection."
"I returned this wire brush and received a refund. I have purchased many different brands of similar sized brushes and none are perfectly balanced however this one was so unbalanced it could not be used in a 115mm Hitachi grinder due to extreme vibration. Can't fault Screwfix's customer service but this product should be better quality."
"I recently bought one of these cup brushes to remove some rust from a chassis I'm restoring. This my first experience with a Titan wire brush of this kind and it was so bad I felt I had to share it. The brush was really out of balance and this caused the angle grinder to vibrate terribly. So badly that I couldn't finish the job with it and had to stop and find a different cup brush (which was fine with very little vibration). The product itself looks fine to the eye. I've used similar cup brushes made by other manufacturers in the past and never experienced a problem. Maybe I was just unlucky and got a bad one."
