I have gotten around 10 of these bits. They ship very fast. Cheaper then what I get them for at my local hardware stores. I love these bits. They can break pretty easy if you are careless and don't know how to properly use them. These are made to run at higher speeds When used on metal. I use them almost daily to cut away at stainless steel. They work excellent ðŸ‘. Their really great for softer metals like brass, aluminum, plastics too @lower speeds. Just an all around great bit. Wide variety of uses. When in doubt, get the tungsten out. Last awhile for me and I'm fairly hard on bits.Just remember high speeds light ish pressure. Don't be in hurry and they won't let you down. Will be ordering from here anytime I need new ones. Very recommend.

I bought this cutter to make a square hole in a metal stud - the type of metal studs used to hold up drywall in high-rise apartments/offices. The cutter worked great, it moved through the metal stud no problem. I did however have 2 problems that I'm writing this review so that others can benefit from my experience:1.) The cutter is relatively short. I was trying to cut metal that was behind some drywall. So the cutter had to be long enough to get through the drywall and through the metal. Because of an obstruction on the wall surface, I had to hold the tool about 1.25" away from the metal. This made it so that only the very tip of the cutter would contact the metal. While it worked I can comment that the tool is very short, so consider you application before buying.2.) The cutter is very brittle. I actually cracked the shaft of this tool and could not complete my job. Because of my particular use, the cutter was bouncing around a bit in the slot I was cutting. This caused the bit to break. After it broke, i used the remaining portion to try to cut again. It broke a second time.Final recommendations: This cutter is good for controlled cuts in mild metals where you can brace/secure the work and the tool. This tool is not very good for free-hand cutting as I was doing. Make sure that you control the tool well to prevent bouncing and cracking of the bit. I think I will re-try with a thicker-shanked bit. Perhaps 3/8" if I can find one.

I needed to remove about 1/8-3/16 inch of steel from a 1 inch slot so a disk grinder would not work. The steel was about 3/16 inch thick. There were four slots to do in total. I also had never used a Dremel to remove steel. If you keep the speed no higher than medium and be patient, you will get the job done. If you try going to fast, the Dremel may overheat and you may get bouncing on the bit. The bits did the job. I bought two expecting to either break one or wear one out, but I never used the second bit. Did it with one bit. The job took just about 15-20 minutes. I would definitely recommend the bits.

Used it to shave off door lock to fit a door that would not close. No sparks on the metal and worked. Now door closes. Highly recommend.

TThe Dremel 9901 Tungsten Carbide Cutter, Silver works well in my DREMEL TOOL, and serves as a CHAIN SAW Chain Touch Up Tool, for sharpening the chain, without removing the Chain from the cutter bar.GREAT for my requirements in the field.

Usual Dremel quality, there are cheaper knock-off versions available but you get what you pay for.
