Notches in the tube wall may allow internal components to be viewed directly for positioning or assembly operations.
If the notch width exceeds I.D. minus 4 x wall thickness, the notching tool action must be tangential, rather than radial, to keep distortion of the tube to a minimum.
In parts under 2" in length, Notching can be combined with tube cutting, for cost savings.
