Six of the jihadists were killed by aerial bombardment on their hideouts while 12 died in a shoot out with police forces, the military said in a statement. It did not say how the other nine were killed.
Security forces also arrested 114 suspects and found and destroyed a training camp which included a shooting range, an obstacle course and an underground conference room, it said.
The military did not say whether any of the security forces were killed in the last few days.
More than 100 jihadists and at least 22 soldiers have been killed in the wider-ranging operation launched on February 9, according to army figures.
Security forces have sought to quell attacks by an Egyptian jihadist group that later declared allegiance to the Islamic State group (IS) since the military ousted Islamist president Mohamed Morsi in 2013, following mass protests against him.
The jihadists have also killed scores of Christians in church bombings and shootings.
