My old Milwaukee sander is from either the 80s or 90s. When the pad disintegrated, all Milwaukee parts websites said the pad is no longer available. I saw this one (with a different part number) was the right size and the screw holes looked to line up. So I got it, and it fit on perfectly. I don't think the sander will ever die, and now I should be good for another 100,000 miles. THANK YOU for carrying this item.
