Not sure exactly what video your referring to, but most carbide cutters can be used successfully on wood as well as metal.
WARNING: Rambling below....
The thing about having a machine for both metal and wood is that the spindle speeds are so radically different for the two. The tooling may be the same, but the spindles are vastly different. The spindles that do cover a broader range cost a premium, and even then, they don't cover enough of the range to be really considered "dual purpose". When I think of speeds, I think 60-2500 rpm for metals, 12,000-30,000 for wood. Most people build their machine for either wood or metal, not both. You can cut metal with a high speed spindle or router for wood, but it has many drawbacks, and you shouldn't expect near the results you achieve with a milling machine. Some people have more than one spindle. If you make a simple attachment for a router, you now have a suitable secondary spindle for wood. The same goes for high speed engravers. Most of the wood guys have an attachment for those too. Also, keep in mind that if your going to be cutting metal, the rigidity of the machine needs to be far far far more stable, than for wood. Any flex at all, and you get broken cutters on the tips. After that happens....well, you've got years of machining experience to know what happens when using dull or broken cutters. This extra rigidity equates to a much higher price in the machine build.
I know I went into more than what you asked for, but you stated that you have years of machining experience, so naturally I'm thinking you want to achieve results close to what your used to with metal working machines. You also state your plans for a spindle, which tells me that your building, rather than retrofitting. You also state that you want to cut wood. This raised an eyebrow, and I felt some common misconceptions needed to be, at least, brought up. With a bit (tons) of research and a little (a lot) care in design, you can achieve a machine capable of cutting both wood and metal, but it's not really possible to get both without some versatility. I'm not trying to dissuade you in any form or fashion, just a friendly "heads up" from my personal opinions. Take it with a grain of salt. When you start your build, keep us posted with pics and such. We feed on pics like a cow in a field. Can't get enough!
