DEWALT DW8311 4-1/2-Inch by 5/8-Inch-11 36 Grit Zirconia Angle Grinder Flap Disc

Is not the same threads as one bought previously- so if you dont use it immediately are your just out of luck? please take a look at my previous Dewalt (and other) 5/8-11 thread purchases- there is something wrong with this disc

These things are great! They saved me so much work just on my first project that theyve already paid for themselves. You just need to remember to keep moving at all times or these will make a hole in a hurry.

Second time buying these and would buy again. A great option. Lasts way longer than regular sanding pads so worth the extra money.

Used a few of these flat wheels to refurbish a rusty mower. Worked slick and so much better then a flexible abrasive disc. Anyone with a 4-1/2 grinder should have a few of these to go with the other discs.

I have always used these types of grinding discs for cleaning up metal surfaces. They dont chatter and when light pressure is applied the surface is polished. They work better and last longer is pressure is kept to a minimum so the work piece doesnt heat up, even just the pressure of the grinder is enough as these discs remove material quite fast.

Bought this flap disc sanding wheel to specifically work with the Makita dust shield that I am using on a cheap Kawasaki 4 1/2 variable speed grinder that I got on Amazon. The dust shield attaches to my vacuum and really helps keep the dust down when Im grinding on fiberglass.

It does what I want

It works, nothing too special. I find the cheaper Home Depot discs just as effective. I am using it to take off old paint on a steel toolbox.

The best ive found. used mostly on carbon steel tube and hot roll steel sheet. They last a long time. even at the end of life and hard as a rock, they are still perfect for deburring or chamfering.

works great, as expected.
