Drill cut parameters for Depths, Passes, Feeds and Speeds are the same as the toolpath Cut Parameters. There are a couple additional parameters that are unique to drill points.
Diameter by tool vs. Exact diameter
If Diameter by tool is selected the drill point will only be a point and the size of the hole will be based on the diameter of the tool at the given depth.
If Exact Diameter is selected, a diameter larger than the tool diameter can be specified and the drill point will be generated as a circle. The circle will be sized to create a hole with the selected diameter using the tool dimensions at the given depth.
When using Exact diameter, EnRoute accounts for the shape of the tool when determining the drill path. For example, a drill point generated with a conic tool where the drill depth is less than the conic bevel height, the real diameter of the tool at the drill depth will be used to generate the drill path.
The image below illustrates drills defined with both Diameter by tool and Exact diameter.
Countersink
The Countersink option is available when using an engraving capable tool (conic, engraving, tapered) and Diameter by tool is selected. Countersink allows the specification of the outer diameter of the countersink hole and then automatically calculates the depth of cut based on the tool dimensions.
