The following chart shows estimated numbers only. AutoDrill normally suggests running conservative speeds and feeds whenever the cycle time is not critical. By controlling the heat build up and taking a proper cut, you can make a cleaner hole and tooling will last longer.

Note that some materials such as Stainless Steel tend to drill better when you take an aggressive cut. This is partially because the drill tool is going through fresh «cool» material rather than an area that was heated up from the previous pass of the cutting surface. Always check with the tooling manufacturer for suggested RPM, thrust and feed rates when possible.
