15. A method of manufacturing a tool, the method comprising:
forming a body with a forward portion including at least one mechanical interlocking feature in the body, and at least one channel, wherein the at least one channel is oriented from an outer surface of the forward portion radially inward toward a longitudinal axis of the tool;
positioning an ultrahard insert in contact with the forward portion of the body;
filling at least a first space in the at least one mechanical interlocking feature in the body and a second space outside the body with a matrix precursor, such that at least a portion of the matrix precursor is positioned in the at least one channel; and
curing the matrix precursor at a curing temperature less than 2,200° F. to form a matrix adjacent the ultrahard insert and outside the body.
