I have had two sets of blades sent to me by Infinity Tools. Then the second set had end to end taper of.025 to.030 inches. The first set had alignment hole issues; off center by.015 inches. I had to wait 4 months for replacements. Can't get flat results, let alone any blade life, with one edge doing all the cutting. I went back to DeWalt for close tolerance product.
We have a DeWalt DW735 Planer that has been used a lot while building our new home. These knives are an exact replacement for the original. They are easy to install.
These immediately showed signs of wear and nicks. Maybe I'll mill some flooring and replace the wood floor in the Living room. 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. Surprising since all I was running was small amounts of pine. Not one nick.
I went through two sets of knives for a few hundred linear feet. Only dulled the knives. talk about being really, really annoyed. 5) The OEM knives really need improvement. My first thought was what have I done.
For a homeowner, I use this tool a lot. The rest of my shop is mostly DeWalt and I've been happy up to that point. Guess the DeWalt rep was right. Starting with a fresh set, I went through three sides (1.5 sets) of knives. The first major project was a window replacement. The thicknesses varied from 4/4 to 5/4.
Talk about nicked blades. Well, I thought, yeah, right. Since it was a refurb, the DeWalt money back satisfaction guaranty did not apply. 2) The in-feed and out-feed extender tables are not optional. Its just not the same experience using a friend's which was purchased new. Did not seem intuitive but the proof was in the results.Lessons here, 1) Do not buy a refurb. I milled the trim myself out of pine using the planer and a router. Something positive.This last week, I purchased 40 boards of mostly 8" x 12' (some 10" x 12') oak from a local sawmill.
Especially if you are planning to feed in boards longer than 2 feet. The knives have been a sore spot for me.The original set of blades came with nicks on the blades (refurb). Positive, first hand experience with the tool. Thats why I bought the DW735 in the first place. Figure about 2400 linear feet or 1600sq feet. Consider also getting roller stands. I am going to try the after market replacement blades and report. DeWalt was good enough to send me a complimentary set of new knives.
4) Pine is harder on the knives than hardwood and more likely to cause nicks. I can replace a set of knives in minutes at this point, however. I planed them all to a uniform 15/16". I could not imagine feeding 12 foot boards without the extra support 3) The DeWalt stand was another good purchase. Its all about making a nice home for the family.
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.
It's good to have a planer for finishing wood, re-doing deck's etc. These knives are definitely easy to replace and they do the job well. 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). The only problem is that they are expensive, probably no more than other types of planers/knifes, but still expensive. Overall happy with performance.
