Thank everyone for your help. I am cutting with 1/4" compression bit at 90 ipm and 12k-13k RPM based on your recommendations and 50% allowable tool deflection from a feeds and speeds calculator. For...
Richard thanks for the suggestion! The only reason I could think the two would be different would be flute design but hopefully the Amana numbers are not realistic and I can get more from the took I...
