I'm looking to buy a random orbit sander, specifically a Dewalt. At lowes there is a Dewalt pad but under description it says that it fits Porter cable sanders. The only Dewalt pad i can find is for the DW421K and DW423K but they are discontinued. will either of these pads work with a dewalt sander? I'm looking at the D26451K for $59.99 at lowes.
I don't know if this applies or not but I have replaced the pad on a pneumatic sander before. It was just a threaded stud on the pad that threaded into the sander. In fact I changed it from a 6" stickon pad system to a 5" hook and loop and it worked just fine. IIRC it was a generic item I got via either Amazon or Ebay.
There really shouldn't be a need to change the pad on a ROS for years, short of damaging it. On sanding discs, most relate to the number of holes and their placement in relation to the pad for dust collection.
