Abstract:
A cutting tool for milling solid propellant for rocket motors includes a cutting arm that is fixedly attached at a center location to a rotatable arbor or shaft. The cutting arm has a cutting blade and inwardly located hole at each end with each of the blades facing in cutting position substantially parallel to the axis of rotation of the arbor, the heels of the cutting surfaces being ground off to avoid or eliminate drag and resultant friction on the milling surface.
