Abstract

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 (23) and an elongated central section (24). Preferably, the overall length of the cutter is 1.5 times the width. The cutter may also include a raised cutter edge (18) for chip breaking during cutting.
