4 Inch Flap Discs, Akamino 20 PCS 40 60 80 120 Grit Assorted Sanding Pad for Angle Grinder, Compatible with Dewalt Makita

Got the fast. Just what I wanted!

As a few others have mentioned, these discs do not come with the grit marked on each one, and they are for 4” grinders, not 4.5” Each pack of 5 discs comes marked with the grit, so I just took a Sharpie marker with metallic ink and marked each disc. Not a big deal. My biggest issue is that the measurements of the inner diameter rings that fit over the grinder arbor are pretty sloppy. This prevents you from tightening them down and they have a tendency to spin freely on start up. 5/8” should measure 0.625” but I found that a lot of the discs were over 0.64”. I checked some of my other discs that work well and stay snug, and found they are all in the 0.62” range. I included a few pics of measurements of these discs purchased from Akamino/Amazon and a few from other vendors. I also included a couple pics showing the difference of the extra space around the arbor for these discs and for other grinding discs I had. They seem to hold up well for the limited amount I’ve used them, but I’m not really excited about using them is they cause the arbor nut to loosen up frequently.

Work for what I’m using them for

work great on metal and wood just dont hold it on either very long they remove alot real quick

On one pad and I've done a fair amount of fiberglass sanding. Was nervous if they would hold up, but they are. Only complaint I have is each wheel is not marked with the grit size. There is one sticker on one pad in each wrapped package. I had to mark with ink pen on each wheel as soon as I opened the packing wrap.

Good quality.

Not assorted as stated. I only received 120 grit. I will still use them but it is not what I ordered

so far first disc used is working well, individual disc's are not labeled with grit but each pack of five are
