The most important thing is that these actually fit my Chicago Pneumatic CP7545-B - Air Grinder which is a huge relief as the only place I can find the name brand ones want $47.00 plus tax and shipping! Second, these are really good quality and are just as good as the ones that came with my grinder. I wish they were a little longer (which would add a little leverage) as sometimes the locknut on my grinder can get pretty tight after using a heavy grinding wheel. I can always weld a little extension on it fairly easily if I decide I need it. I am wrapping the handle with self-splicing rubber tape which should make it work just fine without the extension. I am so happy to finally find one of these that work with my grinder for such a reasonable price that I am not really complaining about the length. The price and the quality are just as awesome.
