Using regular bits and chisels,** A: I can't speak for the keyless version of the Bosch 1/2" chuck adapter. But I have the keyed version of Bosch's 1/2" chuck adapter! The keyed version, employs a a special chuck body with a sliding shank, that (like an SDS chuck,) transmits the percussive energy directly into the back of whatever tool or bit is installed in the Jacobs chuck. I used my adapter to fit a 30" x 1-3/4 bulb auger, into Dewalt's 18volt SDS+ roto hammer. Then used this combination, for several days, in the rotor hammer mode, without a failure. (A roto hammer fitted with a bulb auger, is my tool of choice when the task is the extrication of woody shrubs, and their gordian root systems!) **Q: Which is better, Bosch key or keyless construction?** A: Keyless is better specially if you start drill and forget key is still in the chuck **Q: Is the SDS Shank removable? Does the chuck loosen when operating in the opposite direction or is there a flat spot to lock the chuck on the shank?** A: Yes, it locks in place just like a bit would. Works great, I used it to mix mortar for 2K feet of floor tile. **Q: How do you lock it into position so that it is not moving up and down?** A: Thank you for your question. The HA3JAW adapter works the same way the SDS-Plus bits work. They lock into place in the chuck.
