These just arrived today. Quick shipping. Nice personal touch with a signed card from who pulled and shipped them. Plus it came with a sticker (always love it when they include stickers, a guy can't have too many can he) and a 10% discount on carbide bur for die grinders. I like how the discs aren't flat but rather cupped back towards the tool so you're using, so a greater area of the disc is in contact with the work surface and you don't wear down the edge near as quick. If they work well I'm inclined to purchase from them again at the regular price.
