The price is good and I’ve ran that standard Delta DP at work before we upgraded.

But I’d say he pulled that #out of his wazoo. If he actually measured TIR (total indicated runout) with a dial indicator, he would have a number…. not a range.

Personally…. I’d say .005” is on the boarder line of acceptable.

.010” is pretty sloppy, and you’ll visually see long bits visually wandering at low speeds.

If it’s not too far, take a nice long smooth shaft (if you have an edge guide for your router, one of the shafts might work well) or the longest shank router bit you have. Chuck it up, cut some holes and feel it with your hand.

If your gut tells you “dang, that’s pretty wobbly” listen to it. And treat yourself to a Big Mac on the way home to ease the pain of walking away (which will be much lesser than wrestling with a bad tool for years).

ETA….

Run out can be caused by stressing the DP when using a cylinder drum sander….. and that won’t be repairable.

My Grizzly has .003 TIR, and though it’s acceptable for all off my woodworking tasks, it still burns me, as I purchased the DP new.
