I'll also chime in that 30amp service to the tool is what is required. You always round up from "total" to the needed circuit size with very few exceptions, if any. My slider has essentially similar specifications to yours from a motor perspective and it's running cheerfully on the 30 amp circuit mandated by the manufacturer. My J/P has the same rating. The 3.5hp motor on my BS is happy on a 20 amp circuit.
I use twist-locks on all of my big machine circuits. Yea, they cost a little more, but they don't disconnect if accidentally bumped. I like that "positive" locking feature.
