1. An apparatus adapted to be conveyed within a conduit disposed within a wellbore and to cut the conduit, wherein the apparatus comprises:
a body;
a combustible material configured to produce combustion products when the combustible material is ignited, wherein the combustible material is disposed within the body; and
a swirl diverter configured to direct the combustion products radially outward toward the conduit for cutting the conduit, wherein the swirl diverter comprises helical grooves extending from an upper end of the swirl diverter to a lower end of the swirl diverter, wherein the upper end of the swirl diverter is disposed within the body and the lower end of the swirl diverter is disposed outside of the body such that the helical grooves extend from within the body to outside of the body, and wherein the helical grooves are configured to rotate the combustion products as the combustion products flow along the helical grooves from the upper end of the swirl diverter to the lower end of the swirl diverter.
