Easy to get hot under the collet when overly enthusiastic about cutting hardwood and the paint on it is The wave begins to melt. You can still get lost in the heat of battle, but at least you don't have to scrape the hot gunk off the carbide tips. I've done away with companies that insist on labeling their products with colored paint. After a year of use, I still have a table saw blade that sometimes leaves red streaks on some woods.
