Delta 22-549 Replacement Knives for Delta 13-Inch Planer

Customer Reviews & Comments
These knives are not the thickest planer knives out there, but the Delta 22-580 planer is overall a nice machine, especially considering the price. I have noticed some chipping in my planer knives. But all planer knives chip. It's just a fact of life. They will certainly chip if you forget to remove a staple. They will chip if they hit a piece of sand or dirt. They will chip if they hit a knot (I recently chipped mine on some pine knots). And sometimes they will chip for no obvious reason whatsoever. This is true of this planer costing a few hundred dollars, and it is true of planers costing thousands. When they chip, you will see small ridges down the board. Note that if you see this, then SOMETHING caused this chip since it is very unlikely that both of your knives will chip in the same place unless there was something rough to cut on your board surface. There are two simple and free ways to deal with this: 1) Note that you can move the blades slightly left and right. If you want to, you can move one blade to the left and one to the right, and thus, the chips will no longer line up and you will be left with a smooth surface. 2) Once you thickness the board to the right size, keep the cutterhead locked, and run the board through another pass. Since it's unlikely that the board is inserted exactly the same way twice in a row, you'll be left with a smooth surface.
