I got mine a week ago…it does the job I bought it for…
Yes but I would not recommend it. This holder is more for getting to a difficult location or around a bend and will give you some torque, but not enough to drill through anything, especially not with a spade bit. If you have a pre-drilled hole and want to widen it some with the spade bit, and it's not a hardwood material, you might be able to do it.
I used it in confined places, works great
It can possibly be damaged if it's not exactly straight. If not completely and absolutely straight when the impact hits it, it will flex defeating the forward impact. I would not use it for such.
It can remove as well.
Technically, this bit holder could be used to drill holes but you may not get the precision you would with a different type of tool.
It just might if your drill bit is very sharp and you don't force it.
Yes, however any decent drill will develop enough torque to ruin the flexible shaft.
Yes, however more expensive drills that produce some torque will ruin the flexible shaft.
