Folks,

I am trying to cut some Dado's for the runners of a table saw sled.
I got my issue with cutting straight dado's fixed, basically it was just a lot of practice and I got a new Craftmans Plunge router with LED lights. The new router is 1/2 the weight of my other beast, and the lights help a lot. The new craftsman has a nice smooth plunge movement as well.

Now my issue is the size. I purchased a Rocker 1/2" shaft straight plunge bit. The specs said it has a 1/4" cut diameter; when I cut a dado, it is smaller then 1/4".
Not by much, but a "off the shelf" slider or T-Track does not fit. Then I have to run another cut which allays winds up wider then I want.

Is this unique to this bit ? or something else ..

Thanks - Fred

Commonplace.
Few cutters are better than + or - .005 on the cutting dimensions.
Shanks are tight but not the rest of the cutter.
What to do? Always duplicate the intended cut on scrap before wrecking good stock.
Learn to measure precisely so when checking the scrap you know what the net dimensions will be on the work.
