Morning,
Both those are drills. The long one is a VERY good drill. Difficult to assign a certain time period to them as there were drills from every time period....best guess could be made by examining other artifacts in the general area...points you can gain a time period from and going from there. If you have a multi-component site...(several time periods together) this will be less accurate, but its about the best you can do.
Drills are neat little artifacts. Its hard to find perfect ones here. Normally they are damaged in some way. Hope this helps.
Happy Hunting
