Reaming versus drilling to size. The geometry of a hole drilled in metal by a twist drill may not be accurate enough (close enough to a true cylinder of a certain precise diameter) and may not have the required smooth surface finish for certain engineering applications. Although modern twist drills can perform excellently in many cases—usually producing sufficiently accurate holes for most ...

Diamond Reaming Shell. The recommended practice is to alternate two reaming shells in each hole drilled to maintain hole diameter. When changing bits, the diamond reaming shell should be checked for wear using the bit and shell wear gauge. Failure to observe these recommended practices could result in a poorly stabilized bit or an undersized hole requiring costly reaming.
