This $8 Harbor Freight T-handle ratchet works with Festool Centrotec 100mm driver bits. The ratchet's bit holder uses a ball bearing that fits in the wire spring detents on the Centrotec shaft. Centrotec bits fit surprisingly well.
I bought it to use primarily with the hex bits needed to adjust the various Festool tools and accessories instead of carrying around a set of T-handle hex drivers. The handle stores individual 1/4" bits.
The T-handle ratchet itself is made from cheap plastic, but has a lifetime warranty.
