13 best corer cutters

Core cutters, also known as hole punchers or paper punches, are tools used in crafting, arts, and office work to create holes in paper or other materials. They come in various designs and sizes, each intended for specific purposes. Here are some common types:

  1. Single Hole Punch: This is a basic punch used to create a single hole in paper.It's often used for binding documents or for crafts.

  2. Two-Hole Punch: This type creates two evenly spaced holes, typically used for binding documents in folders or binders.

  3. Three-Hole Punch: Similar to the two-hole punch, but with three evenly spaced holes. This is standard for preparing documents for ring binders.

  4. Shape Punches: These punches come in a variety of shapes like hearts, stars, flowers, etc. They are popular in crafting for decorative purposes.

  5. Lever Punches: These are usually larger and allow for more precise cutting, often used in more intricate paper crafts.

  6. Heavy-Duty Punches: These are designed for thicker materials like cardboard or even fabric, often used in more heavy-duty crafting projects.

  7. Adjustable Hole Punch: These can be adjusted to create holes at different distances from the edge of the paper.

  8. Slot Punches: Instead of creating a hole, these create a long, narrow slot. They're often used for laminated documents or ID cards.

  9. Corner Punches: These round the corners of paper, giving a smoother finish. They're common in scrapbooking.

Remember, when using any type of punch, it's important to consider the material's thickness and adjust the punch accordingly. Also, take care not to overload the punch, as this can cause it to jam or break.

User questions & answers

Question: Does this work on thin sticker paper? I've tried several different punchers and my sticker paper gets stuck
Answer: There’s an inner lining that MAY make this possible but I would fear that water would leak through and get the foam inside wet. I wouldn’t recommend using it outside. The outer lining has a velvety feel
Question: Will this cut through cardstock that is folded? I need to make wedding fans and want to round the corners
Answer: hi! It's 3x4. due to packaging it looks like that. Once the inside foam is moved around it is a thick mat thats works well
Question: Will this cut 10 mil thick laminated paper
Answer: Yes very easy, especially if you put them in the carry mesh bag that comes with them
Question: Which is the maximum thickness that it can cut? We need to cut a 2mm soft wood
Answer: I would either do it by hand and let them air dry or even tossing them in the washer on a light setting. Maybe stick them together so they all aren’t bouncing around. I couldn’t see it being any different from washing shoes.

User questions & answers

Question: Does this work well with regular copy paper or book pages
Answer: I am pretty sure it would cut it at first. The problem with cutting stickers is it tends to gum up the cutter (my experience with other cutters not specifically this one). If this happens, it might be difficult to clean. Just a thought. Not sure if this would be the case here.
Question: Does this work on laminated paper
Answer: No. Mine wouldn't even cut through one piece of cardstock. Defective.
Question: Did anyone get the Punch board
Answer: I used it to cut 10 mil laminated paper successfully on the M and L sides. I could not get it to cut 10 mil laminated paper with the "S" side.
Question: How to sharpen the puncher
Answer: It most definitely won't cut a 2mm. soft wood. It's a good & precise tool, but only for light duty use. - It will handle business card thickness cardstock, but nothing more. - I have since obtained a Zutter Round-it-All Heavy Duty Corner Rounder to cut the 1/32" card I use. The cut isn't as clean as I would like, but it beats doing it by hand with scissors. Martha Stewart makes an inexpensive heavy-duty corner rounder that I would like to try, but they don't say what the radius of the cut is. (I require a 1/8" radius, equivalent to a 1/4" diameter.) If you search corner rounder on eBay, you will see many varieties from light duty to heavy duty table mounted ones.

User questions & answers

Question: Can this cut .025" Aluminum sheets
Answer: I have had no problems with getting the paper or what ever I’m cutting to have a smooth transition from straight to curved. I did practice with it on several types of paper before actually using it, so I could see how it looked. I have personally been pleased with how this corner cutter works.
Question: Looks like the type of heavy-duty yet not too expensive thing we need for cutting polyethelene (hdpe) sheets... but really need 5/8" (r
Answer: yes it will cut greeting cards. Laminate maybe a little harder but i think it could if it isn't too thick,
Question: Can this cut 3mm pvc
Answer: It isn't hard to push down, but I was disappointed in it because it doesn't trim regular weight paper well and even with card stock, you have to be super careful to fit it in perfectly which isn't easy. I wanted to love it, but I don't
Question: Can the die be reversed to cut notched corners
Answer: Up to a certain weight of paper. Anything 120# and up is gonna be difficult (16pt and up). We've been using it on laminated 100# Cover stock in our print shop. It takes some "elbow" (well, finger) grease doing that, but it gets the job done.

Answer: I used it to round the corner on a magnet I had attached a picture...and it cut it nicely ...I would think it would work on card stock .

User questions & answers

Question: Is this good for rounding 10 mil laminating sheets post-lamination
Answer: I cut 10 mil hot laminating pockets after they've been through the laminator with no real problems.I've been unsuccessful rounding 22 lb paper and even light card stock. All the cutter has done was partially cut the paper and bend the rest of the corner over.I think it will cut the reinforced plastic with no problem. You'd need to make a fast cut and not a slow pressure. Any kind of plastic bodied cutter would not be a good way to go because the plastic body of the cutter is too flexible.

User questions & answers

Question: Does it cut 10 mm thick laminate
Answer: I am not sure. I have not tried to cut such a item. However, I did place a thick sheet of plastic that is not so flexible and a pretty thick restaurant menu just to see if I could provide an answer, and it provided a clean cut. I was only able to place one sheet in the gadget, and I was able to go back to paper with no problem. I hope this helps. Take care.
Question: How do you clean the cut pieces out of the machine
Answer: I shake the cutter after each punch and sometimes have to blow at it a little and the pieces come loose. It's important not to let the pieces build up.
