Apparatus for roll grooving thin wall pipe comprises a housing supporting a female drive roll and an arm pivotally mounted on the housing and supporting a male idler roll. A feed screw between the housing and arm provides for pivoting the arm to displace the idler roll radially toward and away from the drive roll, and a quick release arrangement between the feed screw and housing is operable to release the arm to displace the idler roll away from the drive roll at the end of a roll grooving operation without rotating the feed screw. Self-tracking during a roll grooving operation is provided by teeth on an outer surface of the drive roll which urge the pipe and grooving rolls axially inwardly relative to one another.
