I don’t have a delta but with planners in general if you have a slower feed rate it should give you a better finished board.

it just gives you a better cut quality with less chip out if you are using a figured wood or since the knives cut more often a smoother surface. it wont actually bring the board to a finish ready state

Charles, the planer is designed to use the 60 cpi setting for the initial dimensioning. Once one side is surfaced you should then alternate sides until you are near the final board width. Then switch, while the planer is running, to the 90 cpi setting and make passes on alternating sides until you reach the final thickness. The 90 cpi setting produces a board that is a little smoother than the 60 cpi setting, as Jim and Denis have said. You will still need to sand and/or scrap to get the board ready for the application of stain or finish but the 90 cpi will give you a smoother board than the 60 cpi setting.

That function runs the board through the knives slower for a finer cut. I really don’t know why they added it, every woodworker knows there is plenty of sanding once the joinery is cut, right before glue up. Also after glue up.

It will reduce the sanding time and effort no doubt and anything that does that is good. When you use the faster speed, try taking off as little as possible on each pass. That helps the smoothing.

I’m surprised at the two cutting speeds on this planer, 60 cpi and 90 cpi. My DeWalt 735 is 96 cpi and 179 cpi. And at 179 cpi I do get a very nice finish. DeWalt even says use the 179 cpi setting when planing hard or figured wood to reduce wear on the knives and to reduce tear out. Based on that I’d say run it at 90 cpi all the time. I pretty much run at 179 cpi all the time.
