Annular cutters have been all the rage in the last couple of years as, like many tools, they have become much easier to find and much cheaper. If you are not familiar, they are similar to a hole saw but a lot more precise. Instead of a twist drill bit in the center of the hole saw, which guides the blade, they have a centering pin that just needs a dimple in the material being cut. The diameter of the annular cutter is a lot more precise than the hole saw and has a much different cutting design. F1225 Carbide Burrs
In this video, Project Farm is going to test a variety of them in a variety of materials and will come up with a winner. Use this video if you are interested in buying any annular cutters for your garage.
Annular Cutters: Milwaukee, Hougan Copperhead, Jestuous, Champion, Euroboor, DeWalt, Hermes, S&F, Unibor, Evolution, Steel Dragon, Slugger by Fein. Annular cutters provide a far superior finish compared to twist drill bits or hole saws. Annular cutters tested for cutting speed and durability on aluminum, mild, medium (4140), hard (spring steel) and very hard steel (AR500). For large hole sizes, annular cutters also drill much faster than using incremental twist drill size increases to achieve a hole of the same diameter. Compared to hole saw, a high quality annular cutter offers a higher quality outcome and finish. I purchased all of the annular cutters, the mag drill, and all supplies used for testing the cutters to ensure an unbiased review.
watched part of it. bogus cutters, bogus info, etc, etc. ALL JUNK SCIENCE.
Project Farm is legit. Dude tests real world purchases that people make, (Amazon, eBay, Home Depot, ETC…) through various real world tests. Nothing bogus about it!
Triangular Steel Files stay away from metal and just stick to plastics. did metal/cutter testing in the aircraft world. junk steel is still junk steel
