I bought some abrasive discs from Klingspor’s a while back and have been using them on my power sanders a lot.
The backing is a mesh material. This means there are no holes to line up! This means it is so much quicker, so much better at dust collection too! They really last a long time too! The kit come with 5 different grits (2 of each). 100,120,150,180,220. I have thrown one away. I will be buying these again. In different sizes for different sanders. They are sold in a combo pkg. so you can try them at a very reasonable price. $11.95 fo the 6” $9.95 for the 5” $7.95 for the 3”. You can also buy your favorite grits in larger packages. I like them a lot.
