JESTUOUS Annular Cutter Set 13 pcs 1 Inch Cutting Depth

very nice cutters work excellent

Been using this set for a while now and am very pleased with the results! when or if you get a set besure to use collant/ cutting fluid. don't run them dry or with the improper fluids. overall very pleased with this set.

This is the first set of these that I have ever bought. Decided on these over the more expensive name brand ones because I do not run a shop or anything like that and will not be using them all the time. After using the 5/8" cutter in my mag drill to drill out 55 holes with number 55 drilling as nice as the first hole I realized that I definitely made the right choice saving a lot of money buying these instead of the more expensive ones. I kept it well lubed as you are supposed to do with these. Would definitely recommend at least for someone who is not going to use them all the time.

I only used the 5/8" annular bit and it amazed me! I cut 198 holes through 1/2" steel and it came out to be just shy of 1 minute per hole. Didn't notice any dulling of the bit. Great stuff!

I just used the 9/16” cutter from this set to cut 18 holes in a truck frame. Works great in my mag drill with 3/4” Weldon chuck. The bit performed flawlessly and still performs as new. Couldn’t ask for more.

Cutter set seems well made, sharp and accurate to size +/- 0.001. Nice case. I modified a 3/4 inch milling cutter holder to use these on my knee mill, works very well. Holes are finished to size and with a reamed-like finish. Constant lube is needed with any annular cutters, which are designed for magnetic drills with internal lubrication, but it works fine on my mill with external lube. For any through-hole use in appropriate material, these beat the heck out of twist drills for finish and speed and lots easier than boring. And the price is right. OK, I'm a hobby shop, have no idea how these would stand up to daily industrial use, but they are nicely made and do the job.

Saw a couple of negative reviews on these cutters and was a tat skeptical. After buying these and using them, I LOVE them ! Use some oil whilst cutting and let the spirals fly ! These cut through the the double chassis of my truck with ease.

Needed to drill 100 5/8 inch holes through 1/2 inch plate steel with Drill Press. The cutter was just as sharp when I finished as when I started. Happy with my purchase!
