Petropedia - What is Reaming? - Definition from .

Reaming is a finishing operation that is performed with -edge tools which provide high-precision holes. At a high penetration rate and small depth of cuts, a superb hole quality, close dimensional tolerance and high surface finish are achieved. The operation is performed with the help of reamers which are round cutting tools that enlarge the size of existing holes. Reaming should not be considered only .

17.12.2019· When used correctly, a reamer produces a round, accurately sized hole with a glasslike finish. Reaming operations reasonably should hold diameters to within a ±0.0127 mm (±0.0005") tolerance. Reamers are available in countless sizes and styles. This reamer has spiral flutes, which enhance chip flow like the spiral flutes on a drill. Image courtesy of C. Tate. Reamers are end-cutting .

In order to maintain the original path during the pre-reaming operation, drill rods must be available at the pilot bore exit and connected to a swivel at the rear of the reamer and pulled into the hole. Prior to pullback, a final reaming pass may be accomplished using the same sized reamer as will be used when the pipe is pulled back (swab pass). The swab pass cleans the borehole, removes remaining fine .
