Don't expect long life [Posted on 2008-03-28]
I only recently purchased the DeWalt 735 planer and haven't used it enough to wear out the OEM blades. They've done fine for the limited use I've put them to so far, but I bought it with fairly low expectations re: knife wear. Infinity Tools sells a set of HSS replacement blades that can be resharpened and every comment or review I've read in various woodworking forums says they hold their edge much longer--usually 2x-3x as long. I have a set of the Infinity knives to use when the DeWalt blades are worn.

As I understand the problem with these knives, they are thinner than other knife designs. That is apparently part of the design for the 735, which is a very good portable planer, but does leave the user with the problem of continually replacing the knives, and also contributes to the problem with not being able to sharpen these knives. I was told that the DeWalt knives are 1/16" thick, whereas most planer blades are 1/8" thick. The thinness of the blade is why there are no carbide versions available.

With DeWalt having to be aware of the short blade life, they would have happier customers for the 735 if they would either make their blades out of better steel or price them where it isn't so expensive to replace them frequently.

Infinity Tools makes a HSS replacement blade set for only $4 more than this set. It isn't carbide but it is premium German tool grade steel. That's a start.

No choice but satisfied [Posted on 2008-06-04]
It's good to have a planer for finishing wood, re-doing deck's etc. The problem is supplying the knives to do the job. If you own a Dewalt 735 planer, these are the only ones you can buy (as far as I know). These knives are definitely easy to replace and they do the job well. The only problem is that they are expensive, probably no more than other types of planers/knifes, but still expensive. Overall happy with performance.

ordered to keep on hand when needed. Planer works great. I use small cuts so the original blades are still being used and not even turned over as yet.

OK but not great. [Posted on 2008-09-05]
For a homeowner, I use this tool a lot. The knives have been a sore spot for me.

The original set of blades came with nicks on the blades (refurb). My first thought was what have I done? Since it was a refurb, the DeWalt money back satisfaction guaranty did not apply. The rest of my shop is mostly DeWalt and I've been happy up to that point. DeWalt was good enough to send me a complimentary set of new knives. These immediately showed signs of wear and nicks. Surprising since all I was running was small amounts of pine. The DeWalt rep claimed that while pine is indeed soft wood, it also has pockets of resin and hardened sap that make it harder on the knives than oak or maple. Well, I thought, yeah, right.

The first major project was a window replacement. I milled the trim myself out of pine using the planer and a router. I went through two sets of knives for a few hundred linear feet. Talk about nicked blades. talk about being really, really annoyed. I can replace a set of knives in minutes at this point, however. Something positive.

This last week, I purchased 40 boards of mostly 8" x 12' (some 10" x 12') oak from a local sawmill. The thicknesses varied from 4/4 to 5/4. I planed them all to a uniform 15/16". Figure about 2400 linear feet or 1600sq feet. Starting with a fresh set, I went through three sides (1.5 sets) of knives. Only dulled the knives. Not one nick. Guess the DeWalt rep was right. Did not seem intuitive but the proof was in the results.

Lessons here, 1) Do not buy a refurb. Its just not the same experience using a friend's which was purchased new. Thats why I bought the DW735 in the first place. Positive, first hand experience with the tool. 2) The in-feed and out-feed extender tables are not optional. Especially if you are planning to feed in boards longer than 2 feet. Consider also getting roller stands. I could not imagine feeding 12 foot boards without the extra support 3) The DeWalt stand was another good purchase. 4) Pine is harder on the knives than hardwood and more likely to cause nicks. 5) The OEM knives really need improvement.

I am going to try the after market replacement blades and report. Maybe I'll mill some flooring and replace the wood floor in the Living room. Its all about making a nice home for the family.
