Cut Off Wheels 4 1/2 inch, 10 Angle Grinder Cutting Disc, Cutting Wheels for Metal and Stainless Steel, Welding Accessories, Thin Kerf, Flat T1 Cut-Off Tool, 4.5 x .045 x 7/8”

Wheels are very durable and hold their edge through many cuts. Leaves a nice clean edge when cutting. Fits grinder perfectly with no issues. I will purchase these again as needed. Well worth the purchase price.

Cut a couple of wheel studs quickly. Didn't lose much material off of the disk. A great price for home workshop.

I've used LotFancy FOUR-INCH cut-off discs for years. I love how they're thin and don't remove much metal, which speeds up the task. I'm very careful and almost never break the discs, and wear them down to the central metal ring. However, when I'm using a fresh four AND A HALF inch disc, using a hand-held tool, I can see that even though I'm careful, that thing is bending and warping while it's spinning at incredible speeds. I may have broken some in this "new" condition, but usually not. But it scares the heck out of me to see that disc warping due to my own unsteady hand. IF you use this with a bench-mounted machine, instead of your hand tool, you'll be fine. I just lean to the safe side more than most people. Call me Chicken, but I'll stick to the smaller 4-inch discs.

Cuts rebar super easy. Use in many applications cutting metals

Highly Recommended

These knock-off's are every bit as good as those sold by DeWalt for my DeWalt angle grinder. I've not had one of them 'explode' on me and the wear level seems consistent with DeWalt disks. So far, so good.

not the hardest grinding wheels available, but reasonable price

I started by cutting up a pallet where a saw might have hit nails or kicked back. About 1999, I had removed a 25-foot TV antenna mast alongside the house. The base was seated on the tapered end of a 1-1/16" steel rod driven deep into the ground. I couldn't budge the rod, sticking 5" out of the ground. For 20 years, the hazard sat wrapped in pink tape for visibility. The cutoff wheel removed it neatly and quickly. I kept the pressure light so that heat wouldn't damage the wheel by softening the resin. By keeping the pressure light, I was better able to avoid twisting the wheel in the groove, which might have damaged it. After cutting up the pallet and the rod, I found that the diameter of the wheel was 106.4mm. A new wheel was 106.8mm. I'd call that barely broken in.
