Hey, fellow Lumber Jocks.

Can someone tell me how often planer cutter blades should be changed. I have a fairly new planer with helical cutter blades. I have only planed a few boards, but have noticed what appears to be chip-out over the surface of the board I’m working on. I checked to ensure the cutter was turning in the direction of the grain. I’m thinking I need to turn the cutters, but it seems so soon. I am attaching a couple pictures, but it is difficult to see the pitting. Thanks, in advance, for your help.

I put byrd heads on my 20 in Grizzly and my 221 powermatic. My grizzly head has been for over 2 1/2 years. Has had many thousands of bd ft of lumber through it. The blades are a little dull and it is pulling the 3 hp motor down some but still cut very well. No chipout on the most figured maple. I need to rotate them but you probably don’t need to be in too big a rush. Razor sharp is nice but sharp still works. I know when I had the 4 knife head in the Grizzly I would have to have them sharpened 4 to 6 times a year

Hard to see, but it looks like the chips are being pressed into the wood. You may need better dust collection.

I read a similar thread today on a different forum with the same problem.

I have the same thing going on with my 735. I have it hooked up to a little 10 gallon shop vac, once it gets close to full, which doesn’t take long, the boards begin to look like that.
