I'm new to this forum. I contacted Ridgid service about blade replacements and was told that they did not recommend thin kerf blades, as the cut will be thinner than the spreader. I measured the riving knife/spreader and it was .090 the blade provided was on average .106. I prefer using Freud blades and looks like the Freud LU84R with a kerf of .126 may be the best choice for a combination blade. I have a regular kerf blade on a similarly powered radial arm saw and have been pleased with the results but this matching blade kerf to saw power is all new to me, when it comes to blade selection. Any advise for a rookie?
