A cutting/milling tool includes a tool body, a cutting end of the tool body, a first plurality of cutting elements having a substantially identical shape disposed at the cutting end of the tool body, and a second plurality of cutting elements having a different shape than the first plurality of cutting elements. The second plurality of cutting elements are substantially identical in shape to each other, and the second plurality of cutting elements are interspersed with the first plurality of cutting elements at the cutting end of the tool body. Also included is a method for making a cutting/milling tool.

An affixation and release arrangement includes a first component having a fluid pressure chamber. A piston is mounted in the first component and exposed to the fluid pressure chamber. A second component is affixed to the first component through the piston, the piston being responsive to fluid pressure increase within the chamber to unaffix the second component from the first component.

Improved cutter design as well as an improved design for downhole cutters, such as mandrel cutters and rotary cutter mills. A cutter is described with a rectangular, rounded 'lozenge' shape. The cutter presents a cross-sectional cutting area having a pair of curvilinear end sections and an elongated central section. Preferably, the overall length of the cutter is 1.5 times the width. The cutter may also include a raised cutter edge for chip breaking during cutting.
