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).
15° V-bit: cut width vs depth
Width at the surface = 2 × depth × tan(7.5°). Standard V-groove geometry; the bit's flat tip, if any, adds its own width.

How wide is a 15 degree V-bit cut at 1/8 in deep?
Width = 2 × depth × tan(angle ÷ 2) = 2 × 0.125 × tan(7.5°) = 0.033 in. That's standard V-groove geometry, not a manufacturer value.
