Good bit...availability screwed up.
“Bit is fine. Service from Infinity was pretty lousy. Said the order was in stock. Then did not ship for over a week. When I checked on the order they said it wouldn't ship for 6 weeks (out of stock). I ordered another bit from Amazon-in stock-2 day delivery and tried to cancel the Infinity order. Well, lo and behold, somehow the bit was available and they shipped it. Now I have two of them. Look Infinity, either the product is in stock or it's not. Ex-customer.”
