I love right angle grinders. I have a bunch. I got tired of changing out from cutting disk to grinder to flap wheel, wire brush, etc, that I ended up buying multiple cheap ones, each dedicated to a task while doing metal work. Much easier. though clutters up the work area. I have burned a few out, got a really nice heavy duty Craftsman for the heay work, and I've forgotten how many others. I keep a spare for replacement as needed. Since they common go on sale for $15 or less, it's a no-brainer to have a spare.
