Question: i cannot get the backing away from these discs
Document: These discs are well constructed. The paper backing is the thickest that I have seen and they don't seem to wear out as fast as other discs. I had to wait a month to get them though.
These discs are lightweight but will do in a pinch. They start shedding grit almost immediately and the backing is way too thin. These discs weigh 4 grams each compared to the &#34;Gator&#34; brand which weighs 6 grams. One Gator disc will last as long as 2 Mirka discs.Recommendation:  I would recommend the Gator discs also available at Amazon.
I think he needs a new pad on his sander. I mentioned the discs to my wife, and she was amazed that I would get so excited by something as "stupid" as a sanding disc. She just doesn't understand.
Mirka is far and away my favorite sanding disc. They aren't cheap, but they last! The grit sizes are consistent, unlike bargain abrasives. There is nothing worse than finding a large grit in 220 or 320 grit paper, and it happens with cheap stuff!I can't get these locally, but Amazon Prime and my iPhone app makes keeping them in stock painless!
I have used hundreds and hundreds of velcro sanding discs, first time with this brand. They hold up well! Dont pack up with dust quickly, stay sharp for a good amount of time. The amount of discs you get is a great deal over buying them at the big box home stores! I will order these for my woodshop again for sure.
The reviews said the Mirka discs lasted a long time. They would if I could get them to stay on the sander. I have used many different brands of discs and have never had this problem before. The velcro on the back seems to be very thin and seems to stay on the sander about 15 to 20 min. If you take one off to change grit, it won't stay on at all if you try to use it again. Bad product.
I bought these discs because they were a great price but having used them now I am finding they wear out super fast. I went through 3 discs just cleaning up the top of a table that was not too rough to begin with. The grit on the discs disappears and leaves the paper smooth after a few minutes of use. They did the job in the end but my more expensive discs last longer and don't wear out as fast. I guess you get what you pay for.
I do not understand where the good reviews come from. I am a professional woodworker and usually use Norton sanding discs. After reading the reviews of Mirka discs I decided to give them a try. What a disappointment. Sanding efficiency dropped off dramatically after a few square feet of sanding, discs wore out in no time. Did I get a different product from those people giving the glowing reviews??? I returned the discs.
Instead of having cheaper paper that gives you the new disc agressiveness, then quickly to the used paper smoothness, which may be a grade finer, and miss the deeper lines from the coarser grade of paper in the previous step. Additionally the backing paper is stiff enough to do the job. That way you don't wind up with a buggered edge on your sander. The 6 or 8 hole paper is nice for the dust free environment.
Mirka makes great sanding products. These velcro backed pads work well and when attached to a vacuum set up get great results while controlling dust.
Answer: yes
