Downhole mills and improved cutting structures
A drill bit for cutting through a downhole metal structure includes a bit body having a central axis and a bit face. The bit body is configured to rotate about the central axis in a cutting direction. In addition, the bit includes a cutting structure disposed on the bit face. The cutting structure includes a plurality of circumferentially spaced blades and a plurality of primary cutter elements mounted to each blade. Each primary cutter element has a forward-facing primary cutting face. Each primary cutter element is made of a whisker ceramic composite.
