I needed a stainless steel wire brush for my grinder to clean aluminum for MIG and TIG welding . This brush appears to be well made, but it has a serious problem. It's very thick (about 3/4 inch), heavy, and very unbalanced. Everything on the table to which my coffee grinder is attached is shaking. I want to contact the seller about this issue, but there is no way to contact the seller. I wouldn't recommend this rather expensive brush unless you want to ruin your bench grinder's bearings. [edit 9-3-14] My last recommendation may not be fair. I received a bad wire brush that was out of balance. ...Maybe one in a thousand. I don't know if the rest of their products are defective. I liked the brush sleeve system.
