The FT-8004 handpiece is backwards compatible with the FT-801 station.
This conversion kit allows current users of the FT-801 to upgrade to the new FT-8004 handpiece to experience increased performance and blade alignment without having to purchase a brand-new station.
The C5012 or C1573 handpiece holder for the FT-8002 can be upgraded to fit the FT-8004 handpiece by replacing the receptacle with the B5247.
