50 Pcs Metal Cutting Discs 1-1/2'' Fiberglass Reinforced Cut Off Wheels with Four 1/8 Rotary Tool Mandrels for Metal Cutting Discs (1-1/2'')

does the job, durable if used properly

These are much better than the traditional cutting wheels for rotary tools. I needed to cut the damaged part of a fender off so I could unbolt it after an accident and didn't want to use a deeper & more dangerous angle grinder. These worked very well to cut a 4' long curve by hand with a rotary tool, don't break as easy, and last a fair amount of time for what they are.

These Dremel cutoff wheels work extremely well and are very durable. They will easily cut through thinner gauge mild steel, which was my use case. Unlike the regular Dremel cutoff wheels, these last for many many cuts and are less prone to shattering. Now for a few cons, non-off them which have to do with the actual cutoff wheel. The screw for the shaft to mount the disks is not reverse threaded, which is not screwed down tight enough will undo itself while cutting. Second is the packaging. They come in a zip-lock bag, which does not protect them so well if they are not shipped in a box (mine weren't). However none of the disks were broken, so I suppose that is a testament to their durability. All in all, I highly recommend these. Excellent value for the price and quantity you get!

These are great cut off wheels! Very long lasting and an unbeatable price! Highly recommend A++++

These cut off wheels outlast my standard Dremel cut off wheels by a factor of 10 at least. Very pleased with their performance.
