I didn’t notice any difference when I put new blades on mine. Are you using a different brand of replacement blade?

Yes. Replaced my blades which helped but it’s still the loudest tool in my shop. Right up there with my compressor (oil-less pancake). I just dont do any planing after 10pm.

The helical head planers are considerably quieter, as only an inch (or so) of blade is banging into the board at any one moment. But my traditional planer is loud even when no wood is moving through. If I remember correctly, the belt in mine is a toothed belt, and I think that’s where most of my noise is coming from.

Much of the noise from the Dewalt 735 is from the blower motor that forces chips out the exhaust port. The blades add some additional screaming. I have never tried to disconnect or remove the blower motor, because the dust collection is so good with a standard dust collector.
Has anyone experimented with that?

potable planter?...

too low?

That’s what I hear if I read it out loud. Yeah they are noisy (most universal motors are). Your blade solution will be short-lived but those tiny little cheap ear plugs help a lot. Haven’t seen anybody suggesting a use for the wax they accumulate yet but give it time.

First time I used mine, my wife came running out to the garage because she thought there was a tornado siren going off in our neighborhood.

I put new blades in mine monthly (I surface a lot of wood) and no difference in noise level. It is MUCH louder then my 20” RBI planer.

I haven’t had any noise complaints from the neighbours but I try to keep the garage door closed if I’m using the power tools and I always have my ear protection on. The dust collector is pretty loud as well; I don’t know whether it’s better or worse than the planer.

Brandon…do some reading on Hatfields and McCoys. Long-standing feuds start from trivial things. Not saying to avoid it if they are total jack-asses (like one I had a few years ago that screamed at my wife because he could see where we placed the trash cans on our property on pick-up days because he could see them), just choose your battles.

With my ex-neighbor I wanted to erect a fence with a painted image of the “international sign of discontent” facing his property…he wouldn’t see the trash cans and I thought that should make him happy. My wife wouldn’t let me do it.

I used DeWalt blades when I replaced them. Still pretty quiet after a few days use.

My Dewalt was ridiculously loud; I’ve heard multiple times that this was in part to its universal motor, however my 5hp planer with an induction motor is almost as loud.

I tested the theory about the blower producing all the noise (when I had a DW735) by disconnecting it. Made no difference. Later, I had a Rockwell/Invicta 13X6 planer (great planer, by the way) with an induction motor. And it was almost as loud as the Dewalt. It’s the blades. Probably worse on the DW because you have 3 blades in a tight radius turning at enormous rpms. Now I have a Jet JJP12-HH with the helical head/carbide cutters, and it’s so quiet that I’m sometimes not sure whether it’s on (with the DC going, of course).

Byrd does make a spiral head for the DW735. I’ve heard it is noticeably quieter (pun accidental).

I have the Byrd head in my DW735. The pitch of the sound changed a bit, but not the volume. Still just as loud.

Mine is horribly loud; I worry about my DOG’s hearing being damaged, and even MINE w/ heavy ear covered protection (and I’m pretty lax about safety compared to many). Also terrible snipe and destroyed thin boards 11.25 inches; my old Delta 13 inch planer could easily do 6 inches, and I think I’ve even gotten smaller pieces thru it.

Mine made a horrendous noise when one of the blade retainer screws came out while it was planing a board. The dust blower fan on mine does make a lot of noise. Mine also got a little louder when the blades got dull….not a great amount though. Then again, my blades didn’t get all that terrible dull either…after the bolt came out I had a spare set of brand new blades so I went ahead and changed them out. The way it was marking the boards I really expected to see damaged blades, but since they weren’t really too bad I just changed them out so i could hone up the old ones for next time. It is a pretty loud little machine though and I could see how blades that have gotten good and dull could definitely get louder to plane with. I had an older Grizzly 15 inch and it was no where near as loud as my 735. Still, I have never had any planer make wood as smooth as the 735 will.

Always nice to revisit a 4+ year old thread :)

I had a link (can’t find it now) that showed the dB levels of the various lunchbox planers, and the Dewalt was at the top of the list at 102 dB. IIRC, the Makita 2012NB was the quietest (83 dB).

Still, I have never had any planer make wood as smooth as the 735 will.

Come on over here some time and I’ll show you what my 2030 can do (which is considered a ‘finish’ planer) ;-O

possibly the noise has just bounced back from the E layer

The noise that comes from the planer is not the motor noise. Bench table saws have similar motors and are much quieter.The noise comes from knives hitting the wood.

I know this is an older post, but I think it is worth circling back to it. In my original post, I said that the chip ejection fan was to blame for the noise. I have to agree with runwithscissors, because I later removed the fan and it made no significant difference in the noise volume. In fact the RPM sounded a little higher, and the pitch was very winy. So after that experiment I reinstalled the fan.

In my experience, replacing the stock knives made little to no difference in noise level. Even if it did, the knives dull so quickly that it wouldn’t matter. I don’t discount the original op’s experience, I just have a different experience with my machine.

Is the motor part of the noise? Sure. Is it most of the noise? No.
I put a Shelix head on my 735, which greatly improved the blade life and all but eliminated tearout. It also drastically decreased noise volume, as well as making the pitch much more tolerable.

The individual cutters have a different sound spinning through the air. Vs. the stock blades which are like three paddles whipping the air and contribute to the loud sound. With the Shelix, sound level is significantly reduced at no load, as well as when planing.

Now the dust collector and the planer make about the same amount of noise, which is all I can really ask for. Hearing protection still required. With the stock cutterhead it hurt my head WITH hearing protection.

my 734 is the tool in the shop that I’m sure to use my earmuffs with. The new Sawstop is pretty quiet as is my bosch sliding arm miter saw. So, the dewalt planer with my dust collector started up… it’s on with the muffs.

My 735 was replaced with the Shelix right away but don’t seem that loud compared to the high pitch noise from the Shop Vac in my opinion. Even the HF dust collection motor is quieter…I think it’s somewhere in between. I ended up sticking the Shop Vac into an old cabinet it drove me nuts after awhile.
