💡 Straight flute vs spiral flute reamers, what's the difference?

Flute shape changes how chips clear and how smooth the hole is.

• Straight flutes are the all around pick for most through holes.
• Spiral flutes cut smoother in holes with keyways or interrupted cuts.
• Left hand spirals push chips forward in through holes.
