Review on Whiteside Router Bits 3370 - Optimal Diameter for Enhanced Performance by Nick Ross

I am working on a project to convert one hundred and forty 14 foot 1x12 discs into a T&G. I used 2 passes to cut each side with a different set of bits (this was new when I started this project). These new bits allow me to cut each side in just one pass. I wish they weren't so expensive but they work well. - To update. I get about 945 linear feet from each of these whiteside bits. I received 315 feet from a comparable set of Taiwan made T&G bits (Kempston bits). I rerun all the parts until they feel hot and start to smell like toasted wood. I use boards with already finished edges. The cutters simply cut deep enough to accommodate tongue and groove. I will not push beats through the material any more than necessary.
