What the AI looks for in Chamfer End Mills
- Included angle
- Use a 90° included angle (45° per side) for standard chamfers. Use other angles to match countersinks or drawing specs. Chamfer angle is set by the tool and cannot be interpolated by the toolpath.
- Tip style
- A pointed tip lets you engrave and reach tight spots. A flat tip is stronger and lasts longer. Pointed tips break easily.
- Flute count
- Use 2–3 flutes for aluminum and 4 or more for finish chamfers in steel. Chip room vs finish quality.
Brands that matter
- Harvey Tool: Many angles and miniature sizes.
- Lakeshore Carbide: Popular among small CNC shops.
- Niagara Cutter: HSS and carbide options.
What to avoid
- Using the sharp point as the cutting zone, which wears it out fast. Offset down to cut on the side.
