Abstract
A cutting element for use with a bit may include an obtuse cutting edge. The cutting edge may be formed between a cutting face and a slanted face of the cutting element. The obtuse cutting edge may be pre-formed in the cutting element for use with a bit used to mill a window in casing and/or drill a deviated borehole. The cutting element may be positioned on the bit as a trailing cutting element, and oriented to cause the obtuse cutting edge to engage casing and/or a rock formation.
