I have looked at reviews which have narrowed the choice down to either;
Dremel, which seems overpriced but will integrate with the drill system but reported as not being overly strong.
Stanley which seems Ok but again reported as not being overly strong.
Other vice reports seem to indicate failures at the ball locking points or stripped threads when grip is needed.
That said I do try to treat my tools with care, and if I want / need to take stilsons and a lump mallet to any thing, I am kitted out for that
