What the AI looks for in Corner Rounding End Mills
- Radius
- Buy the exact radius the drawing calls for. Corner rounding is a form tool and doesn't interpolate. The tool profile is the finished radius.
- Flared vs standard
- Flared versions blend more forgivingly when tool height is slightly off. They avoid leaving a step or lip at the tangent point.
- Tip diameter
- Check that the pilot or tip diameter fits the feature you're rounding. Tight internal corners limit tool access.
Brands that matter
- Harvey Tool: Deep specialty-profile catalog.
- Niagara Cutter: HSS and carbide corner rounding options.
What to avoid
- Woodworking router bits run in metal.
