High speed drilling of steel is a challenge as you need the power to cut the chip but too aggressive of a tip on the drill causes drill to break.
First place I would ask is the manufacturer of the machine as they designed it and should know how to use it as well as what tooling I needed to get the expected results.
Too high of speed will trash any drill bit so if using normal bits one could idle Peck, spin up the spindle then power off without brake to spindle as it drops into hole.
Another trick of the old before variable speed drills was to pulse the trigger so the drill bit pulses and does not get up to speed.
Requires coordination of pressure and trigger control but it is effective.
It is how switch mode power supplies work too.
