Benchmark Abrasives 4-1/2 Type 1 Aluminum Cutting Wheel 0.040 Thick 7/8Arbor, Metal Cutting Grinding Wheel, Angle Grinding Cutting Wheel Max. RPM 13300-25 Pack

Great cutting disks - very aggressive and make quick work of cuts through aluminum, brass, and steel. Thin Kerf keeps things neat. These are the best cutting disks I’ve used! Good value!

Hard to find item that worked well for my angle grinder. Cut about 8 sections of aluminum angle on one blade

Hot Damn! These things do cut, I am sooo lucky to find these disks.

This is the first cutoff wheel that I feel safe using on aluminum. It not only cuts well, but lasted far longer than I would have expected. Don’t bind it and you will be satisfied with the results.

Used these to cut 1/4” aluminum plate. Worked great.

Worked great! Needed to do a lot of cutting and grinding aluminum as I modified an aluminum flatbed to fit my truck. Normal al-ox cutting discs load up with melted aluminum and either lose their cutting power or shatter. These did the job admirably, cutting the aluminum quickly. They do wear down faster than good al-ox do on steel, but that’s to be expected as they escape the sticky fate of those by constantly shedding to prevent build-up. They also seem to work ok on steel, though I have others I prefer for that purpose. Nice and thin for thin kerfs and quicker cuts. Note: this is for the thin cutting discs

These discs are trash. They pop off the centers and chip along the edges almost as soon as you start cutting. I do this work a lot and have never had a problem with other brands.

Blown away by these disks. I muscled through some 3/16 thick 6061 t6 with ordinary, “good for aluminum” cut off disks. These just blitz aluminum! In the pic, the too and bottom are cuts made with the “ordinary” cut off wheels. The right hand side is from the BA wheel (it’s NOT deburred). Note that CLEAN edge. 5 of 5 - would absolutely buy again!

I’m cutting everything I can get my hands on.
