## Questions & Answers

**Q: Can this adjust to punch 8 1/2 by 5 1/2 paper with 3 holes?  (half sized)**
A: You can adjust this hole punch to a number of sizes. It took me awhile to figure out, but I actually removed two of the five "punchers" and from there you can adjust the others to any distance you desire. I use mine to punch wholes in 8 1/2 by 11" paper cut in half for supplemental readings provided by my professors. In other words, the typical sheet of paper turned horizontally "landscape" and cut in half.

**Q: Will this punch 4 holes, 3.5" center of hole to center of hole?  o<----3 1/2"---->o<----3 1/2"---->o<----3 1/2"---->o   outside/end holes 10.5" apart**
A: Yes this punch can be adjusted to accommodate this setting.

**Q: How close together can you space the punches? i need 6 holes on 8.5" by 5.5" paper  o<--0.5"-->o<--0.5"-->o<----2.5"---->o<--0.5"-->o<---0.5"-->o**
A: The closest the holes can be is just under 1" center to center.

**Q: The home diameter of the punch heads always 11/32? Exist a a lower diameter?**
A: The model 525M is the "medical punch" which has 11/32" holes.  If you want 9/32" holes, select the 1325B.  It is basically the same punch except it is black and has three punch heads.  Up to 4 more punch heads can be added, part number 1025B.
