Durham seamer Mitch Claydon is one of six players who have signed deals with Kent for the 2014 season.
Claydon returned to Durham earlier this week after being recalled from his loan spell with Kent, but he will be a permanent feature at the St Lawrence ground next season.
Kent have further bolstered their attack with the signing of Hampshire paceman David Griffiths, while four of the county's youngsters have agreed extensions to their contracts.
England U19 all-rounder Calum Haggett and batsmen Fabian Cowdrey, Daniel Bell-Drummond and Sam Northeast, who all came through the Kent academy, have all been retained after impressing this season.
Kent chairman of cricket Graham Johnson, said: "To be able to announce that this group of players have signed for Kent is extremely exciting.
"All are ambitious players who seek a positive environment in which to develop their talent. They are also ambitious for the Club and keen to play their full part in all aspects of developing a winning culture.
"Within the group there is a mix of youth and experience, with players coming through the Kent system and others seeing Kent as the place to fulfil ambitions, a blend that is essential in a squad.
"The team this year has shown its capabilities. The aim is to show that capability more consistently and in doing so, to raise both the individual and team performance.
"This group of players have the desire and ability to do that, which is something that should please Kent supporters.
"We continue to look at the balance of our squad - there remain players who are out of contract at the end of this season and discussions continue with them.
"In addition, and where necessary, we will explore positive additions to the squad."
