A cutting tool (10) for removing members downhole from a well bore and adapted to be inserted within a well from the upper end (12) of the casing (14). The cutting tool (10) includes a plurality of elongate blades (32) on the cylindrical body (18) of the cutting tool (10). Cutting elements (42) of a predetermined size and shape are arranged in a symmetrical predetermined pattern on each blade (32) in side-by-side relation in a plurality of predetermined transversely extending rows and a plurality of predetermined generally vertically extending columns. The cutting elements (42) in adjacent transverse rows for each blade (32) are staggered and have different concentric cutting paths. The cutting elements (42E) in corresponding transverse rows on adjacent blades (32A, 32B) are staggered and have different concentric cutting paths. The blades (32A, 32B) of the embodiment of FIGS. 7-13 have a separate recess (50) on the leading face (34A) for each individual cutting element (42E) for precisely positioning the cutting element (42E). Each cutting element (42E) has a groove (42K) for receiving and directing forwardly the extending end of a metal shaving (S) to facilitate breaking thereof from the casing (14).
