1. An apparatus for machining at least one spline in an aeronautical component, the apparatus comprising:
a holder defining an axial direction about which the holder is moveable;
a cutting insert attachable to the holder;
a first alignment feature for orientating the cutting insert at a single orientation with respect to the holder;
the cutting insert comprising a cutting tooth, the cutting tooth comprising a cutting edge, and the cutting insert further comprising a first datum surface which is spaced from the cutting edge by a respective predetermined spacing; and
a coupling for attaching the cutting insert to the holder about a second direction that is perpendicular to the axial direction of the holder.
