I think the second board I put through my planer when it was brand new was a 1×8 western cedar. One of the knots broke loose and chipped my blade or blades. Anyway, I’m tired of sanding that damn line out so I need to turn the affected blade over.

Wanted to know a couple of things.

1. has anybody had any trouble with those screws. Do they strip the tool or are they pretty tight?

2. A quick browse through for replacement blades has the price all over the place. Are they all the same or should I get a special kind. I do only hardwoods now, no cedar goes in the planer.

If anyone is interested, here is an HSS set double sided for 35.99 no shipping with Amazon prime.

Mine were like someone had welded them on, but I was told they’ve fixed that problem. That may be wishful thinking though. I was worried about stripping/breaking them but once I broke one head off using the wrench they give you (that POS that sits in the top) I realized babying it wasn’t going to help any either so I just chucked a star-bit in the drill to back them out (but not to retighten).

I can’t comment on the replacement blades, I’ve been using the ones Lowes sells until I save enough to put a carbide spiral cutterhead in it.

That cutting head is in my future too. I’m in a position where I need to make 6 tables for an art gallery before Oct 4, and all this sanding is killing me.

I think they come out of the factory with someone (or something) impact-driving them in, so they are super tight and can strip easily if not extracted with care.

my way of taking them out without damaging them was to apply pressure inwards (pushing down hard on the wrench) as you twist them open – that way you relieve some of the stress from the bolt/threads and allow the bolt to come loose more easily.

all blades for the 735 are double sided unless stated otherwise (3rd party blades)

Get your air compressor out, and blow the dust out of the allen heads. That way your wrench will fully seat in the bolt. I never had any trouble changing blades.

I would recommend flipping all blades, rather than just one. If the blades are still sharp, and the nick is the only problem… you may be able to correct it by sliding the knives all the way to the side. Ie: nicked blade full left, good blade full right etc. However, the best bet is to change them all.

I source my blades from Home Depot or Lowes, and they are usually in-stock.

Good luck!

Do you have an impact driver on a cordless? If not do you have any other impact driver? You’ll save a lot of misery the first time you try to loosen them bolts…it’s are hard to keep the needed downward pressure needed to avoid stripping them out while you are also trying to spin them.

Just as an example (not related to woodworking) old Cub Cadet needed a tear-down that required bolt removal…I hit it with liquid wrench and HOT torch…several times…thinking I was going to have to drill them out anyway, I hit them with an air impact wrench. I was able to bear down and let the tool do the spinning. Seconds later I was done with all 8 bolts.

First thing is to get a good high quality bit this will make a world of difference on any hard to loosen nut or bolt.

I do not know which bolts you have in yours. I had the old style which were very difficult to get out and ended up buying a new set of bolts which are Torx headed.

I bought my replacement blades from Infinity and think that they are much better than the DeWalt

Not familiar with that particular planer and if they can be resharpened, but I get my blades for my grizzley planner resharpened down off of 31st and southwest Blvd for like $15. If you need more info pm me.

Russell, here is a good tip. Your planer has 3 knives. I’m not sure how the DW knives seat, but on most planers there are little nibs that stick up and you put the knife on. the knives have elongated holes. Instead of flipping or replacing them, Slide each knife over in the opposite direction a bit. The nick won’t be perfectly aligned anymore.

Since the nick is in a different spot on each blade, the next blade will clean up the nick left by the previous one. I tripple the life of my knives by doing this trick

+1 lumberjoe If you look at the factory blade, it actually has a little triangle on it. I always start all three blades all the way to the left, with the triangle pointing right. Then I slide a blade to the right when a blade gets a nik. After all three are are slid, I flip them, and justify to the right, now the triangle is pointing left, and I repeat until replacement. I wrote this in sharpie under the cover to remind me.

P.S. The downside to the 735 is not having re-sharpenable blades. I have had the most success with factory blades, and paid about the price you posted.

you can also run the board twice each in a different spot relative to the nick in the blades, not a perfect solution but better than sanding

I reversed the blades and got an extra set. Cant afford to have a nick while I’m in production mode.
