Compass Circle Cutter (CMP-1) - Cuts up to 6", Screw-Fixed Blade | Carbon steel blade, adjustable slide, cuts circles up to 6 in - Paper and vinyl circles - Quilters and Crafters

This is a great little tool. I do wish the sharp part of the blade was a little taller, but I was able to cut 4" circles out of 6mm thick foam decking with ease. I took 3-4 passes to get all the way through, but it worked very well. In spite of being made of plastic, it is much sturdier than I expected.

Works like a dream! My little guy had to draw & cut out 80 planets for a school project and this did the job and then some. There is nothing more satisfying then perfect circles lol

I bought 2 reasonably priced circle cutters to use mainly on cardstock. The “JEF” HD-01, and the closely priced OLFA circle cutter. I am reviewing both together. The “JEF” is obviously larger and can do larger holes/circles. This model is easier to use than the OLFA and should be able to cut any circle you would need. My only issue is that it uses a Cricut like blade, and includes 2 extra. The blade works great, it’s replacing it if needed that concerns me. You may just have to buy another whole cutter (although at under$10 not a real problem). The OLFA can cut up to a 6” circle, which covers most card crafting. The OLFA is much more compact and made in Japan instead of China. The OLFA has 6 extra blades and can probably be bought from OLFA. Summary: I really wanted to like the OLFA, but the “JEF” is just so much easier to use. The OLFA has a learning curve and could be difficult for many. I think if you just want to cut circles, get the “JEF”.

When I opened the package and saw this circle cutter, my immediate reaction was, "Oh my God, this is some little kid's toy." For such a small, lightweight tool, this circle cutter is amazing. As soon as I received it, I used it to cut out 15 X 44.7 mm circles in a sheet of translucent vellum on which I had printed colored circles (for my microscope). I simply set the radius of the circle cutter to 22.35 mm using a caliper, and I used a self-healing cutting mat under the vellum. I found an easy way to make sure that the needle point of the cutter was in the exact center of each colored circle that I had to cut. I was genuinely surprised at how well this circle cutter worked. I used three sheets of plain paper between the vellum and the cutting mat, and the circle cutter only cut the vellum--it didn't even cut the paper more than just a bit of scratching. Amazing. I ended up with 15 very accurate, clean-cut plastic circles of various colors. I don't know how long each cutting blade will last, but it doesn't seem to be getting any duller since I started using it. I just used a light pressure, and went around each circle three or four times until the vellum circle popped out. I wasn't trying to make the cut in one or two passes. I'm very pleased with this circle cutter. I have four more sheets of vellum circles to cut (I'm making Rheinberg filters) and I don't think this circle cutter is going to have the slightest problem getting the job done. I bought the circle cutter, cutting mat, translucent vellum, caliper, and even the microscope from Amazon. Talk about one-stop shopping!

I have a stack of 50 I cut out of 6-7oz. leather which is fairly thick for a craft project. I needed a round cutter without purchasing a premade die. This works great although I was very skeptical the first time I tried it. I would recommend doing multiple passes without digging in too hard to try and cut it once. Also, in this application it's almost better to not have a super sharp lade due to it digging in too deep and bogging down the process. I was able to cut this state of 50 in about 1 hours. I use a piece of plexiglass below but a cutting mat would be better. This leather is not a uniform thickness so I do about 4 passes and then movr on to the next one. When the sheet is complete, I go back with a pair of scissors and cut out remaining edges. Doesn't take much time and allows me to not cut my plexiglass trying to get ever edge. Lastly, this is my second Olfa Knife. I have a rotary cutter that is my favorite. Quality products indeed.

So, I found it easier to use by holding the compass/cutter still and then rotating my paper. However, the center pointer pokes through the soft cushion stopper leaving a hole in the middle of my circle (honestly barely noticeable). Also, on my projects, it was VERY difficult to locate the center of the printer circles. This was difficult to align. The blade is super sharp (i cut myself twice😂 my fault) which is amazing for cutting paper, just be careful.

This is what Ive been hunting for forever. It actually can cut a smaller diameter than all others ive found and it comes with spare blades! And even has the parts number from a reliable brand to buy even more replacements in the future. While it is a plastic build, theres next to zero flex or bendability unless i use an unreasonable level and angle of force that would not be standard in its use. The adjustability screws tight and holds throughout use without needing to be readjusted.

Got this to make a punch board for my kids upcoming birthday party. Idea of cutting circles in cardboard was daunting. Didn't see many reviews about cardboard so for anyone else out there it does cut corrugated cardboard. I made 15 circles 2.75" diam with minimal strain and the blade is still has life. Easy to use, cuts paper like butter. Cardboard was tougher but not bad. This is a large pizza box I used same thickness as you typical shipping box. Like the blade cover, pad for when circles are your final product and extra blades and blade compartment. Only reason for 4 stars is would be nice if there were clear actual ruler like markings on the lever part with numerical measures.

Utilizzo il prodotto da molti anni e nel frattempo sono cambiati alcuni dettagli ma comunque l'oggetto rimane assolutamente eccellente,come tutti i prodotti di questa fantastica casa Giapponese (ed e' tutto prodotto in Giappone,con quel che ne consegue..) Leggero,abbastanza robusto,precisissimo,le lame sono eccellenti anche se costano un po'.Perfetto per l'hobbista ma anche per l'artigiano,ottimo per tagliare o marcare legno,celluloide,ovviamente carta e cartoncino,pelle,lamierine sottili per modellismo etc etc,i campi d'applicazione sono veramente estesi.Consigliatissimo,prezzo superaffare (lo ho comprato in offerta a circa 8 euro)

Very nice little item. Good quality, I'm using it to cut wheel dots for vintage RC buggies out of 0.8mm polycarbonate. Couple of rotations and the polycarbonate is scored plenty deep enough to be able to simply snap off the excess. Result is exactly what I was looking for.

Excelente como qualquer outro produto Olfa!

Pretty good. It works mostly as I'd expect and it's compact and easy to use and I really like it, but I may need more practice to use it perfectly. The only complaints I would have is that if you use the little "foot" to not leave a hole in the center of what you cut then it may slide a bit unless you use something else to keep it in place. I've also had issue with the blade not properly reaching the materal when using the "foot". And I'd also add that if the material is more fragile but won't cut super easy it's possible to have it tear a larger center hole when not using the "foot". The one thing I'd like different is for there to be a way to adjust the blade so you can adjust the depth for when you have the "foot" on or off. But it's pretty good, I just need more practice and I'd probably recommend you fix whatever you're cutting so it can't move. But, for most applications I'd say it's good from the limited testing I've done.

Es como un compás pero con cuchilla para poder hacer el corte circular. Funciona bastante bien, después de varias pruebas he conseguido hacer círculos perfectos en papel. No lo he probado para otro tipo de material. Eso sí, se hace mejor con la punta, cuando le pones el protector para que no agujeree el papel, cuesta bastante más hacer el círculo sin que se mueva aunque se puede hacer. De todas formas, el puntito que deja es pequeño y no me molesta. Lo recomiendo.
