Abstract: A modular drill includes a drill body, an insert, and a retaining member. The drill body includes a center hole extending through a first surface of the drill body, and a side hole extending at an actuation location through a second surface of the drill body. The center hole and the side hole intersect within the drill body. The insert is moveably disposed in the center hole. The retaining member is threadedly attached to and moveably disposed in the side hole. The retaining member includes a clamp surface and a bump surface. The clamp surface is disposed closer to the actuation location than the bump surface. When the retaining member is rotated in one direction the clamp surface forces the insert into a locked position. When the retaining member is rotated in another direction the bump surface bumps the insert out of the locked position.
