Read Nick Offerman's article on using a homemade router slide. He mentioned this beat as something he uses in his work. I built an 8 foot 2x4 workbench and needed to level the top. Plugged in and drove into town. Oven-dried Douglas fir cuts like butter. Beveled about 1/4 inch on both sides (48 square feet total) and the chisel feels as sharp as it did when the project started. If I ever get this bit to the point where it needs to be replaced I will be returning to Amana for another 45453 bit.
