I bought tools and equipment for my retired wood shop including router bits. I originally bought a "bargain" set of cutters and assumed the cut quality was pretty standard across brands. When trying to find US made cutters, I found Whiteside and found that all of the cutters were sub-standard. These bits are amazing and of incredible quality, they cut beautifully. From now on I will only buy Whiteside beats. My only complaint would be that I'm not sure if any of the bit bearings are made in the USA. I haven't tested all of my Whiteside bits, but I've seen at least one with a Chinese made bearing. Maybe US made bearings of this size aren't made in the US?
