## Questions & Answers

**Q: This could be attached to a rotary hammer drill to allow straight and leveled drilling in concrete?**
A: This protractor has magnets on three sides and as long as your drill has an iron case, the magnet will adhere to it.  I'm not sure what the constant banging of the from the drill will do to its accuracy.  And trying to constantly watch it while you are drilling is not going to be easy.  I might suggest a drill guide like this:  
Milescraft Drill Guide Rubber | 13350003  Copy and paste it in your browser.

**Q: Is it made of aluminum or plastic?**
A: It is metal and non-magnetic but it is painted silver so I'm assuming it's aluminum. It is heavy for it's size and so far very sturdy. I used it during a Jeep project and it hit the cement floor a few times without any problems. The case is scratched but not dented.

**Q: Does it come with a storage case?**
A: only if you ask nicely
