Not for: Anyone drilling deep holes, which needs a true drill.
What the AI looks for in Drill Mills
- Point angle
- Match the point angle to your drills (commonly 90°, 118° or 120°) if you also use the tool to spot. A mismatched spot angle makes drills walk or chip.
- Hole depth
- Use only for shallow holes. These tools lack the flute length and chip evacuation of a drill. Chips pack in deep holes and break the tool.
- Flute count
- Use 2 flutes for aluminum and 4 for steel. Chip room.
Brands that matter
- Harvey Tool: Most complete drill mill range.
What to avoid
- Using drill mills as general-purpose drills.
