Leverkusen have reportedly already turned down two offers for Schurrle from Barclays Premier League giants Chelsea, while Bayern Munich have made no secret of the admiration they hold for Bender.
Both players were part of the German squad that reached the semi-finals of Euro 2012 under Joachim Low earlier this summer, and have been courting the interest of several clubs across the continent after an impressive season with their club.
Nonetheless, Voller insists that Leverkusen will not be willing to entertain any offers for the pair as they are both important to the club's long-term future.
"We could have pocketed more than €50million for both players had we sold them, but 'no' fell easy to us," he told Bild.
"We will achieve more with Bender and Schurrle than without them, as they have no equivalent substitutes. I am not afraid of having disgruntled players - these guys have a top character.
"I will say it again: both of them will be staying here."
Bender arrived at the BayArena in 2009 from 1860 Munich and made 34 appearances for Leverkusen last season, while Schurrle, who joined just last summer from Mainz, scored nine goals in 40 games in all competition.
