First, I don't use it in a professional production situation. If you need it, buy a Freud. Yonico is best for the hobbyist or occasional carpenter. I bought 3 separate Yonico bits for a project and they are exactly the same! Same high quality, sharpness, lots of carbide to re-sharpen, shanks long enough to fit my Jet 2 HP shaper to allow enough movement across the table. My son will use them in a Festool router. Wide range of profiles, allowing to create a variety of decorative edges and profiles. Two downsides. The inner shelves of the crate came loose from the bumps during shipping because they weren't adequately nailed to the sides of the crate. Luckily none of the bits were damaged as each bit is held firmly in a plastic collet that is attached to the shelves. So I took another reviewer's suggestion and Brad fixed these shelves tightly. The packaging for the box was in good condition, it was just poor design of the box shelves. Also, I need to remove some of the bits from the collets, they're stuck in there! You may need to use a special tool to gently pry them out of the collets - don't use your fingers, these things are very sharp! Also, this is a great set of bits, much better than buying them individually.
