Each row summarizes the published values for that bit and material across all machine classes (open a size for the per-class breakdown). ⚠ = the manufacturer's chart feed doesn't match its own chip load (see bit page).
30° V-bit: cut width vs depth
Width at the surface = 2 × depth × tan(15°). Standard V-groove geometry; the bit's flat tip, if any, adds its own width.

How wide is a 30 degree V-bit cut at 1/8 in deep?
Width = 2 × depth × tan(angle ÷ 2) = 2 × 0.125 × tan(15°) = 0.067 in. That's standard V-groove geometry, not a manufacturer value.
