Review on Whiteside Router Bits 1500: The Ultimate Solution for Precise 90 Degree Cuts by Andrew Schreider

Whiteside's 90 degree cutter is the best you can get. It's sharp as a razor, and that sharpness lasts for a very long time. The attached photos show what I use this bit for. This bit cut the black background of the first character and the green background of the second character. One person said the black background looked like a pile of coffee beans. The only problem is that this bit is very short. I would give five stars if it was a half inch longer. Due to the short length there isn't much room to see where you are cutting. This is the shortest bit I've ever used.
