Roller reamer

Roller reamers are employed in boring operations for the oil & gas industry.

Additionally, the second function of a roller reamer is to keep the drill stem in the center of the hole at the specific position of placement of the roller-reamer.

Size of circulation passage through the center of the body of the reamer typically range from 1 1/2" to 3 1/4" in diameter.

The body size on the necks beyond the area where the rollers are mounted typically range from 4 1/8" to 11" in diameter.

When two sets of three rollers spaced apart longitudinally are used, the roller-reamer is called a "6-point reamer".
