In Tatabánya, handball boasts a long history. The game took place in an organized form from 1942, within the framework of the Tatabányai Bányász Sport Club (TBSC). The transition from the big field to the small field handball, which was ordered by the Hungarian Handball Association (MKSZ) at the end of 1959, was a fundamental change. Tatabánya could start its new role in the Western Group of NB II. In 1966, TBSC became the champion in the Western Group of NB II, allowing him to start at the forefront. The members of the NB II champion team included Alfréd Antalóczy, Vilmos Drobnits and Sándor Kaló. At the end of the season, with only a worse goal difference, they were eliminated from Nemzeti Bajnokság I. Sándor Kaló became the top scorer with 160 goals. The association (MKSZ) first announced the single-group NB I/B championship in 1968, which was won by the TBSC with a great advantage and was able to be included in Nemzeti Bajnokság I again. From here, the "golden age" of the Tatabánya KC team lasted more than twenty years. In 1969, TBSC made history in Hungarian handball, as it was the first rural team to win the Hungarian Cup. The members of the cup winning team: László Szabó, Ferenc Sándor (goalkeepers), Sándor Kaló, Lajos Simó, László Katona, Ernő Bakonyi, Tibor Bognár, László Fekete, Antal Schalkhammer, Imre Molnár, Alfréd Antalóczy, László Vörös. In 1974, Tatabánya KC became the first small-scale champion in the history of Hungarian men's handball, breaking the hegemony of the capital. The members of the championship team: László Szabó, Ferenc Sándor (goalkeepers), Ernő Gubányi, László Katona, Lajos Simó, Sándor Kaló, László Fekete, Pál Pavelka, Lajos Mészáros, József Bognár, Mihály Hegedűs, Ottó Szigeti, Ernő Bakonyi, Jenő Flasch. In 1978, Tatabánya KC became the champion for the second time and also won the Hungarian Cup for the second time. The members of the team: Béla Bartalos, László Szabó (goalkeepers), Sándor Kaló, József Bognár, Gyula Básti, László Katona, Lajos Mészáros, Ernő Gubányi, Jenő Flasch, Árpád Pál, Lajos Pánovics, Zsolt Kontra, József Hernicz, László Bábos. The club won the championship twice more: in 1979 and 1984.

The fact of the redevelopment or closure of the Tatabánya Coal Mines was felt in 1990: salaries and other benefits became more and more limited. László Marosi, the six-time goal king of TBSC, has been certified for the German Bundesliga team, TBV Lemgo. The following year, the staffing of the team underwent a huge change. Nine key players left and still could not retain their place in the top class. The Tatabánya KC presidency gave the team one year under similar conditions to return to Nemzeti Bajnokság I. The team took the opportunity to win the 1992/93 NB I/B Championship unbeaten in their group and were at the forefront again. The team commuted up and down for a while between the first and second divisions. In 2001, László Marosi, a world-class handball player, became the managing director of Tatabánya KC. This team returned to Nemzeti Bajnokság I in 2002. In the 2009/10 season, the team won a bronze medal in the league after many years. In his ranks with players such as Ivo Díaz, Gyula Gál, Gergely Harsányi, Máté Halász, Gábor Szente.
