Ken, I also own some of these. They look a bit different colour wise to the standard CTC HSS. They last much longer and cut through mild steel a lot better than their HSS (which incidentally are not bad). When I used them a couple of months ago I was also pleasantly surprised.

Here's a test for you Ken. Run it over some K110 and let us know how it fares.

Bob, the names' cupid; not stupid. We already know what it does to 1" endmills don't we.
