1. A downhole cutting tool, comprising:
- a body comprising;
a cutting end;
a connection end;
a longitudinal axis extending axially through the body; and
a gradient composition having one or more gradients, each gradient extending a distance in a respective direction through the body, and each gradient comprising changing amounts of a first material in the gradient composition along the respective direction in which the gradient extends.

Abstract
A downhole cutting tool has a body that includes a cutting end, a connection end, a longitudinal axis extending axially through the body, and a gradient composition having one or more gradients. Each gradient extends a distance in a respective direction through the body. Each gradient has changing amounts of a first material in the gradient composition along the respective direction in which the gradient extends.

18. A downhole cutting tool, comprising:
-
a body comprising a cutting end, a connection end, and a longitudinal axis extending therethrough; and a first gradient composition comprising a progressively decreasing amount of a first material in the composition along a first distance from the cutting end, the first gradient composition forming a cutting end portion of the body. - View Dependent Claims (19, 20)
