SUNJOYCO 40PCS 2 Inch Flap Disc Set with 1/4 Shank Disc Holder, Roll Lock Quick Change Sanding Discs for Die Grinder, 40/60/80/120 Grits

Worked perfectly , with variety.

Please know that this review is based on 20 minutes of experience by a picky guy. Amazon asks for reviews within minutes of the purchase, hence so many 5 stars on junk.As to performance so far, I've been happy. They cut well. Wear rate seems reasonable. But there are many variables when it comes to flap disk efficiency and durability. For now, I'm satisfied. Need more time before a final verdict.So why the 4 star? Labeling! The pack I bought contained 5 different grits. The baggies of the different wheels were clearly labelled. Good. But there is no identification on the individual wheels as to what they are Heaven help you if you spill these guys on the floor and have to re-sort them. I'm a visually impaired old guy who as been doing shop for decades now. Frustratingly, I can't easily spot small differences in grit sizes any more. Should the grits be different colors? No, not really. Certainly a pain for the manufacturer. How about a label on the reverse side of the backing plate? Should be a piece of cake for them. I understand that these wheels are consumables and nobody wants to invest much in making them. But as a user, I really want to know what I have in my hand regardless of circumstances or prior partial use.Buy again? Maybe, but I'll look for better grit ID.

I use them removing rust on restoration project. Do the job and last.

They do what they a designed to do. Having different grits is nice.

Not really what I expected they don't really measure up to what I needed

They were made cheaply and didn't last that long,blew through most of them in no time

Work great for coping wood trim as well as metal work.

great price and on early delivery ... will b ordering again. having a custom fab shop I go through consumables like these quickly & can't find better deal anywhere
