5Packs Indestructible Disc for Grinder, Upgrade Indestructible Disc 2.0 - Cut Everything in Seconds, 4 Inch Ultra-Thin Saw Blade Diamond Cutting Wheels Composite Multifunctional Cutting Saw Blade

Good cutting wheel ! But making sure the blade will fit your grinder. I had to enlarge the wheel hole by the universal drill bit.

Well guys I am 1 bolt in and the blade shot craps a quarter of the way in. These are junk. I donot recomend them at all. Okay for metal sheeting or siding but nothing bigger than that. The siding was basically torn not cut. The bolt on the other hand heated up and that was all. I went back to the black cut off wheels to get the job done. I ordered 5 of these green blades and I am throwing them away.

My husband said these were just what he was looking for and they were the right size for his saw!

3 stars because they will cut but only 3 stars because these things are far far from indestructible....If you want an actual high grade cutting disk then balls up and pay the money and buy a bad dog disk. Between their warranty which I haven't had to use yet and how long they really last, bad dogs pay themselves off in about 1month of regular cutting disks "for me anyway"

Makes things simple

Didn't wow me but they did the job

The advertisement for the leading competitor warns would-be buyers to avoid the cheaper, foreign-made products but, despite that, I decided to give the 5Packs Indestructible Disc a try. I loaded the first disc into my Dewalt grinder in order to cut off the bottom part of a steel bolt. Ten minutes later, the disc had managed to get only half way through the 1/4" diameter bolt. Just to confirm the bolt wasn't made of some kind of tempered steel, I installed an older, heavily used, blade and, not surprisingly, it cut through that bolt and a second in less than 30 seconds.If you want to make your heavy-duty cutting chores easier, this is NOT the product for you.

These blades are really impressive. They grind/cut like crazy and are incredibly durable. I still have not gone through more than one of them and I've cut wood, steel, concrete, rock, lag bolts and all sorts of things.They don't crack and they don't spray you with broken pieces of disk and they make like a hot knife through butter on most materials.The only thing they do not do as well as a normal "grinding wheel" is grind, obviously. But if what you need is a disk to cut nearly anything you can imagine, these will do you perfectly, last you a long time, and make you glad you have them on hand.
