1.0 out of 5 stars Does not work well with D28402K, February 12, 2010

I recently purchased the Dewalt D28402K 4 -1/2" grinder with this backer pad and a pack of 36-grit sanding pads (for refinishing a deck).
Out of the box this pad will NOT work with the D28402K. The locking nut is simply not long enough to grab ahold of the spindle. The instructions were non existent but eventually I went to DeWalt's website to see if anyone else ran into this issue (before I started removing material off the backing pad to get it to fit).
Apparently the fix is that you have to remove the washer and inner spindle on your grinder to get this POS to work.
I'll be trying this after work today but this is total crap. Why would DeWalt require you to modify your grinder so that it works properly with a DeWalt backing pad?

Makes absolutely no sense.

Well as usual we are expected to buy more chinese crap and just accept the fact they will soon be our overlords.... This product did not fit my angle grinder(DEWALT D28402K ) without modification. Furthermore the hand tightened locking nut is shoddy at best to handle RPMs of 1200. This should have the same wrench tightened nut that the grinding disks have. I can already tell that changing the disks out will be a real bear....

The instructions don't tell you that when attaching to the Dewalt 41/2" grinder, you actually have to remove the washer assembly that you normally don't remove when using a regular grinding wheel. Easy to remove, and once done the backing pad goes on easily.
I am about to use the tool to do some aggressive sanding and paint removal on my house gable trim. I'll give you and update.
