The Kity 619 Table Saw is similar to the Kity 618, but more developed. Its sliding table saw is longer and more stable and sophisticated. A slightly newer version is the Kity 1619, which is for the most part the same machine.
Kity was taken over by Scheppach in 2004, after which the Kity brand was scrapped, and the 619 was continued as the Scheppach Precisa 3.0. The later editions were produced in China. It is unclear if the earlier ones were produced in France or China.
Many modern off-brand China-made table saws also seem to be based on this machine, for example the Holzmann TS250 and the HBM 254. These are probably made in the same factory as the Scheppach Precisa machines, but with slightly different specifications.
Replacement Saw Blades: The Kity 619 can take blades up to 280 mm, which is quite an unusual size. If you want the largest blade, there are only two choices on Amazon UK (With 48 teeth, or another with 64 teeth for finer cuts). On Amazon Germany, there are also two more expensive options, which you can find here.
Alternatively, check the selection of 250mm blades, which means you can cut slightly less high, but choose from a wider range of blades.
