Calvan 39-300. I bought this used and it still had 5 inserts left. I used one on a van. It worked perfect. still has 4 inserts. Note the pic of the drill bit. It has a couple grooves in it, At first I thought it was broken but I don't think that is the case. It worked great for me. I think these are allow chips to be pulled as you drill. It was like this when I got it and worked fine.
