Scott, most flooring has a relief in the center of the bottom. I do not remember the reason for this but it was important for some reason. As far as the bits go I suggest you purchase Whiteside for this job. For 900' you will need at least two sets of bits and I would suggest three sets and returning the third set if not needed. If you want to try and get by on one set them you should buy a quality sharpening set like this one from Trend. (about $50) If you are near Detroit come see me and I will show you how to use it.
