(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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ here are the instructions! no instructions provided, but once you figure it out, works great *by T***I on August 23, 2024* Unbelievably, no instructions are provided on how to make it usable as a three hole punch.I could not find any online diagrams or advice.This is what I figured out in about an hour of fiddling about:1. Unscrew and take out two of the five punches. You have to take off the split ring on the column first, or the punch will not slide off. The ring is there to prevent the punches from sliding off.2. You do need a pretty wide screwdriver to loosen and tighten the screws, wider than the normal kind. Maybe you can use a kitchen tool or a big coin.3. You have to play with the paper back stops on the leftmost and rightmost punches so the paper stops at the right place. Very weird for the manufacturer to not pre-mark the standard place. This took the most time, fiddling with the back stops.4. You might need a plier to hold the square washer in place while you screw and unscrew the screws. This was awkward and time consuming.Once you figure it out, it works great. If you do the above, then it won’t β€œflip over.”I think many people were frustrated and understandably returned it to Amazon. The manufacturer should have provided a one page illustratedvinstruction sheet!I will never use a 9/32 punch again: 11/32 makes the paper pages in a binder so much easier to flip through!This was a revelation, that 11/32 is a superior hole size! ### ⭐⭐⭐⭐⭐ Very Nice *by K*** on November 30, 2024* I received the 5 hole punch and it is in perfect condition. Love it ### ⭐⭐⭐⭐⭐ High quality and durability *by C***N on June 22, 2024* I purchased this for a large project with work and it has been an excellent and highly durable product. I would highly recommend this five hole punch for anyone looking for a quality product. ## Frequently Bought Together - Martin Yale 525M Master Hole Punch, 11/32" Hole Diameter, Punches Through Up To 40 Sheets of 20-lb.
