Considering that you are basically telling me I am not doing what I am actually doing? Yeap.
Even your own link points to the same part numbers.
Even if you want to say they don't make these any more you wrote they did not make them at all.

Using a router? Buy Onsrud's singe flute cutters (63-600 series) - McMaster under "Router Bits for Aluminum" (ex PN 3317A21, 3317A25).

Using a mill? Check out Maritool (Uncoated, ZrN, DLC) or Lakeshore Carbide (ZrN). McMaster sells the TiCN Niagara tools (High-Performance Carbide End Mills for Aluminum).

Never said TiAlN was the only option. Go back and look. Don't much like people assuming I did when there's no evidence to support the claim. None the less I will once again agree with you with the right machines these are perfect tools.

I *only* use TiAlN mills with specific circumstances and *never* suggested otherwise.

I am very disappointed in the way you are reacting to this.
However it is utterly irrelevant to the fact that it does work.

Before it was implied that people were surpised that Niagara would suggest the applicability of TiAlN even though they don't sell it well that can't be a fact.
If you simply look through the Niagara price list the TiAlN end mill part numbers are still very much in there.
Both the PDF and the ASCII price list dated January 7th, 2013.
Old or not they obviously have experience with this coating on aluminum.

Now if I were in Niagara's shoes and I was selling a product that a whole bunch of people made a directed effort to dismiss I would probably shelve it as a matter of business as well. Regardless of the product quality or track record if enough customers simply decide it is not for them the volume of sales would plummet (like what would happen if a bunch of people kept going after people over it...sort of like what people often do to BobCAD and MasterCAM). It sure seems like this is a little too much peer pressure for a simple matter like this. So I guess I know why Niagara outright said to me it's just not worth worrying if they disagree. I haven't even bought these products from Niagara so I guess this is an issue they've had pushed on them before.

Besides on their actual page:

Maritool also has this:

So on this I agree to respectfully disagree.
Frankly I just get paid too much to sit around worrying about whether TiAlN is acceptable to anyone.
