"stringy" steel is actually a good thing in many ways; metal dust is bad.

The stringy turnings can be used for stuff like homemade steel wool.

Perhaps magnets are a solution?

If you have a magnet in the home location or something, the spindle could move there and deposit its strings fter each drill.

Unless your spindle motor and spindle driver are capable of instant reversing, you will have to wait for the motor to stop, then reverse, stop again, and restart, which could be a lengthy procedure, not to mention being potentially detrimental to the spindle and/or driver in the long term.
