ABSTRACT:
A safe cutting tool for cutting and undercutting samples of solid material e.g., from solid rocket propellant wherein a blade curves sidewise around an opening to define a sleeve, the edges of which are opposed cutting edges which bevel into the opening from each opposed outside edge. The tool is employed in cutting channels in solid material and can be mounted on a handle, either in axial alignment therewith or at an angle thereto for undercutting purposes. The tool can be employed for excising a sample of solid material e.g., by cutting channels therearound and then undercutting such sample to free same. During cutting, shavings or cuttings of the material pass up the beveled blade and through the opening in the cutting tool sleeve, which cutting can then be grasped and removed by the operator. Such cutting tool, with rounded cutting head and opposed interior directed cutting blades, cuts through solid materials with reduced effort and increased speed and cuts on back and forth strokes, with reduced scrap waste and reduced dust for improved safety, e.g., when cutting explosive propellant material. The tool is particularly useful and has the above attributes in the undercutting of solid material including rocket propellant.
