Has any one used tipped wood cutting sawblades on a milling machine for cutting metal, if so what were the results?

It will work with aluminium - but use WD-40 or similar or kerosene (paraffin) as a cutting fluid and a lubricant. Use side/cheek-plates as you would for cutting wood - and for the same reasons.

Those wood-working TC blades can be made to work on brass (cut dry) although I'm not at all sure that I'd use them on steel unless very necessary.

I certainly would not use blades for mitre/docking saws (for cutting wood and or aluminium) as they can have close to zero or negative rake and are made for "climb" cutting - which would be highly dangerous on most mills with any significant end-play and/or back-lash.

Oh yeah, works great. Here is a little arbor I made to hold carbide tooth trim saw blades (big box store, around $8 ea) Blade has a metric sized arbor hole so it wouldn't work with any of my existing slittle saw arbors. The finished shaft is 5/8".

It is great for sawing blocks of aluminum, touch of WD40 as mentioned. I have also used it for steel and with the correct feeds and speeds it works just fine. One nice thing about these blades is a very thin kerf. Also, the toot is wider than the blade, like a side cutter, and I've never had the blade jam up. I am sure it would work just as well in a horizontal but you would have to find some way to enlarge the arbor hole.

No need to enlarge the hole, just make an arbor that fits an end mill holder for your spindle taper.

Or, if you haven't got one, and your taper is an odd one, make an end mill holder..... or a saw arbor directly. You will want an extended nose to get it out where it can do some good.

At that point, just making a suitable full-length saw arbor could be the solution..... it's only a little more work.
