S SATC 5 PCS Cut Off Wheels 4-1/2x7/8-inch Metal&Stainless Steel Cutting Wheel Fits Angle Grinder Saw Grinder Metal Cut Tools

They cut like butter! Great deal at that price.

Unbelievable cutting ability and they seem to last forever.

I havent had. Long enough to know the longevity however they hold up great so far

Very true, flat, round, hard, sharp grit. Sails right into whatever challenge you tackle. Dang sparky. Have fire safety handy. Don't use your expensive Foster Grants cause you'll pock the lenses.

The metal ring shield on this 4-1/2" cutting disc has the right size inside diameter but the hole in the fiber disc on the other side is too small to fit on my tool. It binds on my Makitta 4-1/2" grinder tool number 9557pb. When I try to tighten, the metal ring bends before seating flush. Filing or sanding the hole larger in the fiber disc works. So does turning the disc backwards if you don't over tighten and do lightweight work. Install it flush to tool, no air gaps, no debris, no bending, or it becomes a dangerous projectile.

Great price and good longevity cutting stainless steel stock.

Best thin cutoff wheel for the money!The thickness is 0.040" = 40 mil.

Worst cutting disks I’ve ever seen by far
