An expandable tool includes a body and a recess extending at least partially through the body from an outer radial surface of the body. A spline insert may be at least partially positioned in the recess and coupled to the body. The spline insert may include a single spline or multiple splines. A cutter block or other expandable member may be at least partially positioned in the recess. The cutter block or other expandable member may include a spline on a side surface thereof, which spline may be engaged with the one or more splines of the spline insert. Engagement between one or more splines of the spline insert and spline of the cutter block or other expandable member may allow the expandable member to move radially outward from a retracted position to an expanded position, and vice versa.
