I got the set from MLCS with a wide range of spiral upcut bits in HSS. I’m making the super sled by John Nixon and in his video he uses solid carbide upcut bits to cut through 1/2” plywood from home depot. I’m using the same material but with the HSS bits some thought I’d take it a bit easier and tried to go 1/4”. The bit burned almost immediately. I then tried the 3/4” bit at a depth of 3/16ths and the tips started to burn on that bit as well. Am I doing something wrong here or are these bits just really cheap? My feed rate was pretty consistent and I didn’t think I was pushing too much.
Would the solid carbide bits have issues with burning if I tried to go all the way through like John does in his video?
