卡勒夫/Cramo

1998–2005: early years

Founded in 1998, the club started out as Canon Eesti noortemeeskond (Canon Estonia junior team). The team was coached by Allan Dorbek and played their home games at Kalev Sports Hall. The club's first season was a disappointment as they finished in last place without winning a single game. In 1999, Ehitustööriist became the official name sponsor of the team. In 2003, the club merged operations with Audentes and became Ehitustööriist/Audentes. However, the merger only lasted one season and Ehitustööriist continued independently.

Ehitustööriist moved to the new Saku Suurhall, now Unibet Arena, for the 2004–05 season. The team also made their debut in the Baltic Basketball League (BBL). In 2005, they won their first Estonian championship, defeating Tartu Ülikool/Rock four games to three in the finals. Howard Frier was named the KML Most Valuable Player (MVP).

2005–present: BC Kalev/Cramo

Coming off their first ever championship, Ehitustööriist leased the trademark "Kalev" from AS Kalev and became BC Kalev/Cramo, while Allan Dorbek, who had been with the team since the start, was replaced as head coach by Aivar Kuusmaa. On 2 October 2005, BC Kalev/Cramo won their first Estonian Cup, defeating TÜ/Rock 70–64 in the final. They also made their debut in a European competition by competing in the 2005–06 season of the FIBA EuroCup, but failed to advance past the group stage. The team successfully defended their Estonian League title in 2006. In the finals, BC Kalev/Cramo edged TÜ/Rock four games to three, winning the deciding seventh game 69–68. James Williams was named the KML Finals MVP. Despite guiding the team to a second consecutive KML championship, Kuusmaa was replaced as head coach by Veselin Matić ahead of the 2006–07 season.

In the 2006–07 season, BC Kalev/Cramo won their second Estonian Cup, but were unable to defend their league title, losing to rivals TÜ/Rock in the finals. The team also finished top-six in the Baltic Basketball League. Travis Reed was named Most Valuable Player in both the BBL and the KML, while Valmo Kriisa won the Estonian Basketball Player of the Year award. The team saw limited success in Europe, reaching the second round in the 2006–07 FIBA EuroCup and competing in the 2007–08 ULEB Cup, where they failed to advance past the group stage. The team won another Estonian Cup in 2007. Prior to the 2008–09 season, Nenad Vučinić was hired as the new head coach. BC Kalev/Cramo went on to win their fourth consecutive Estonian Cup.

In December 2009, Vučinić left BC Kalev/Cramo and was succeeded by assistant coach Alar Varrak. The team struggled in the 2009–10 KML season and finished the regular season in fourth place. In the playoffs, BC Kalev/Cramo lost to TÜ/Rock in the semifinals, but beat TTÜ Korvpalliklubi in the series for the third place.

BC Kalev/Cramo struggled early in the 2012–13 season and on 24 November 2012, Kuusmaa was fired and replaced by assistant coach Alar Varrak.
