deploying a sidewall coring tool into a wellbore extending through a subterranean formation;
rotating a coring cylinder of the sidewall coring tool back and forth less than a full rotation while pushing the coring cylinder of the sidewall coring tool against a bore wall of the wellbore;
pushing the coring cylinder of the sidewall coring tool into the subterranean formation to enable extraction of a core sample of the subterranean formation; and
retracting the coring cylinder to retrieve the core sample of the subterranean formation.
