Has anyone who has a CDC Humbee edge grinder had to replace it? I'm looking at a (new?) Dewalt 5.3 HP 7/9 in grinder model D28499X CDC could not tell me if this particular model would work or not, I'd like to replace the current one with cause its burned up. BTW has anyone ever heard of a 9 in grinder diamond wheel? I plan to stick with the 7 " configuration but curious...
