I have a small Brazilian piece of flooring wood. It's a species they're trying to get here but the government won't allow it yet. On the back it's written "Santo Polo". The people who gave it to me say it's very common in Brazil but that's all they wanted to say. Strange. Toxic wood, protected species, special properties, brush wood? All possible.
You absolutely need good carbide or diamond for Palm and Padauk. Teak is worse than Padauk as inclusions account. An idiot ran a piece in my planer, by the end of the cut, fire was about to break out.
For Palm, try a band saw at slow speed with bimetal blade.
Last year I found something that really works for me. Instead of buying top notch 10" blades at 200$ a pop, I tried one of those Diablo(Freud) blades for circular saws on the table saw. They work great! They're only 8 1/4" but it takes care of most cuts. The best advantage is that since those blades were designed for battery operated skilsaws, they're only about 1/16" thick and are made with a slick surface. An other advantage is that the speed at the tip of a tooth of a smaller blade is slower than the speed at the tooth of a bigger blade. That's a trick from way back when carbide was a rich man's tool. Those blades cost around 20$. Sharpening a good 10" sawblade costs 16$...And since a 10" blade will only take 5 sharpenings it's a no brainer
