I just happen to like orbital sanders and keep 2 of them plugged in and ready when I’m finishing. One has 180 grit and the other has either 320 or 400 grit on it. Now comes the problem – I’m not a fan at all of hook & loop paper, I much prefer psa. As a matter of fact, the only h&l paper I have is the 3 pieces that came with the new sander I bought today. Now come the second problem, the new sander has a 4 mounting hole H&L pad. There is not a 4 hole psa pad to be had ANYWHERE ! It doesn’t exist. I know because I spent a couple hours on the net and even called a couple suppliers – nobody makes a 4 hole psa pad.
Sooooo when this dummy realized I had to do it myself, it took longer to find the right size drill bit than it did to ‘make’ my 4 hole psa pad.
No sense going into any more detail, suffice it to say that I drilled the good 3 hole pad on my nearly dead sander to match the new 4 hole pad, installed it with the new screws and good to go. Now I guess I had better order a couple new psa pads before they quit making them too. I have found that a new pad will last about 6 or 7 years in my shop.

It not the disc – it’s the pad I had a problem with. I think all of the H&L discs are 8 hole. I use a pressure sensitive adhesive disc that has no holes. It’s a solid psa disc used in the auto body shop industry. I tried the H&L discs ONCE and destroyed more than I wore out because of how I use them I guess.
The random orbit sander industry just assumes that you will bow down and use what they prescribe, NOT !
Yeah,I know I have a dust problem but I also have a mask and a good dust collection system

Your problem with H & L is the hardness of the pad and the sander. On my electric PC sander I do tare out the holes. On my air sanders I have both hole and no hole and psa and H & L I don’t have this problem. I think the reason that I don’t have this problem is the speed and the quality of the paper.
I also have two Festool orbit sander and both are H & L and no problem.
I get all my paper from http://www.industrialabrasives.com/ from these people. It comer in boxes and always stays flat. Better paper last longer.
I stop using sanders when I get 320 paper and then only hand sanding with the grain.

I checked the link for the paper – which one do you like , the rhyno or the reline sticky ? The prices are in line with what I’ve been buying so I’m going to try one. Would like to know which you prefer tho -
Not sure if the hardness of the pad is so much the problem as my not paying attention to what I’m doing. I always seem to catch a hole in something and destroy a piece of paper long before it’s time.
Festool ? WAY outta my price range, my craftsman and dewalt random orbit do the same job.
