Previously on Bad Karma "R"Us (me):

1) Purchased half center on ebay - buy it now. Shows 10 available. Seller emails me and says they don't have any after all.

2) Purchased "Bison" half center via Amazon 3rd party seller. Seller sends me a Japan center in a phony Bison labeled box. Returned to sender and finally got a refund. Left appropriate feedback. Seller not happy and claims it was an "honest mistake".

3) Sent multiple emails to brassandtool.com inquiring about current price and shipping cost of Bison half center. No response.

4) Purchased another Bison carbide tipped center (full) on ebay - buy it now. New old stock - $20. Finally got a good tool!   

5) Got an email from brassandtool.com (24 days later) asking if I still want the center.   

Now for the question. Can you mill carbide with carbide tooling? I want to cut this full center down to a half center. Do you think I can get away with milling the tool steel portion and the carbide tip?

Angle grinder? At this point I don't really care what it looks like any more. I'm tired of dealing with individuals/businesses that just don't give a damn about anything other than getting your money up front.
< rant off >

grind it, a carbide endmill will just break. whatevers doing the cutting has to be harder then whats being cut

DA

Yeah, I thought as much. Another lost cause. Oh well. At least I'll have a back-up center now for when I gouge the next one.

Well that's a bummer Willie.

Could you use the angle grinder to get most of it off and then mount a stone in the mill and grind the rest off?

I'm going to quit while I'm ahead Ed. No point in ruining a good tool. I just have to learn to accept the fact that I can't afford to buy "wants" vs. "needs" any more.

The neophyte question ... What is the advantage of only half a tip? I am guessing it is related to lubrication but that is based on thin air.

With a half tip you can face right up to the centre of the part.

Aside from facing I've run into problems just turning a smaller diameter due to toolholder size.

Darren, Willie and Steve, thanks for the education!!
