I have no experience with inserted drills, just what I have been told but a lot with spade drills. The advantage of a spade drill over a twist drill is you have options for different materials.

Debris can be removed smoothly along the trench without blocking. Therefore, the cutting effect of the new chip breaking drill is much better than that of the traditional drill. A drill's total chip load, including both flutes is 3% on the drill's diameter, and can be a little less if your nervous. For your .0312 drill, that's about .0009" per revolution. So if you want to use 3000 rpm, the feed would be 2.7 inches per minute. Peck every 1/2 diameter after the first peck of 3- 3.5 diameters deep. Use some oil or coolant.
