I recently purchase a router plate from Hartville Tool. When it arrived, I saw that there were tiny nibs around the outside edge, 2 on each side for a total of eight. They stick out about 1/16 of an inch. According to the package, they are intended "to keep the router plate from shifting".

My question is, when routing the cutout for the plate, do I dimension the hole for the overall size of the plate, including the nibs? Or do I make a slightly smaller hole, less the nibs? If the former, doesn't this leave a gap around the edge of the plate equal to the depth of the nibs which will collect sawdust and potentially snag a piece of wood? And if I make the smaller opening, do I just force the nibs into wood of the table?

Another option is to just file the nibs off.

Has anyone else dealt with this issue?

Thanks!
