What is the difference between DeWalt’s DW733, DW734, and DW735 planers? We have the answers.
DeWalt makes three different planers that are all very popular, the DW733, the DW734, and the DW735. But what is the difference between them? And can they all be upgraded?
The most important difference between the three planers is where they can be bought. Because, why look at the technical differences of a machine that is not available where you live anyway?
In the US and Canada, the DW734 and DW735 are widely available and very popular. However, the DW733 cannot be bought new anymore. It is quite common on the second-hand market though.
In Europe, it’s actually the opposite. The DW733 is still available for purchase, whereas the other two machines are not. The reason for this is unclear. The DW733 and DW734 are very similar, so it may make sense for only one to be available, but that the DW735 isn’t available in Europe is strange. Especially considering its success and popularity in North America.
The DW733 and DW734 are almost identical machines. The only significant difference is that the DW733 has two resharpenable blades, while the DW734 has three, two-sided, disposable blades. Both have their advantages and disadvantages.
The biggest advantage of disposable blades is that they are much easier to set up and replace. You don’t need to manually adjust their process, which can be an extremely tedious process for sharpenable blades.
This is because disposable blades are always the same height. When sharpening blades, material is removed and the blade becomes shorter and may even become slightly skewed. That is why you always need to recalibrate their position in the planer.
Resharpenable blades have a few minor advantages. If you are able to resharpen them yourselves (for example using this jig), you can save on costs of purchasing replacement blades. You can also pick your preferred angle for the blades, and even add a micro bevel, which may improve the cut quality.
The DW734 actually has three blades instead of the DW733’s two. This is a big improvement that helps with cut quality. Simply put, because there are more knives in the cutterhead, they make more frequent contact with the wood. This means there is less of a gap between each ‘hit’ of the blade, leading to a smoother finish.
Based on the specifications, the DW733 and DW734 don’t seem to differ that much from the DW735. They have about the same capacity, the same power, and are only slightly lighter than the DW735.
However, as you can see from the images, the DW735 has quite a different design. It is engineered more like a stationary planer, built around four threaded rods over which the head moves up and down.
The DW735 is built to a higher standard than the other two planers. It is heavier and uses an overall more solid design. This makes it much better at dealing with continuous, day in day out use than the other two planers, which are more meant for small hobbyist workshops.
The feed rate of a planer is the speed at which the wood is pulled through the machine. The slower a board moves through the planer, the more often the blades come in contact with it. This results in a better cut quality, because there are less gaps between each cut.
The DW733 and DW734 only have one ‘normal’ feed rate. The DW735 actually has two. One ‘normal’ speed, for getting your work done at a reasonable speed, and one ‘slow’ speed, for finishing passes. This finishing speed is nearly twice as slow, and gives much nicer planing results. It also helps with dealing with difficult, reversing grains and figured woods.
Another main upgrade of the DW735 compared to the DW733 and DW734. A common complaint about the two lunchbox planers is that the dust collection shoot tends to clog up.
On the DW735, DeWalt has actually added an extra blower motor that forces all the wood chips out, even if you don’t have a shop vac attached. Check out the video by Matthias Wandel below to see how effective this is.
All three machines can be upgraded with a Shelix Cutterhead. These cost around $400, depending on where you buy them. You’ll have to judge for yourself whether that’s worth it (it almost doubles the cost of the DW734, for example). But it is without a doubt that it is a major improvement.
Shelix cutterheads (also called spiral or helical heads) consist of many small blade inserts. If you happen to hit a nail and create a nasty nick in your blade, this means you only have to replace one small insert instead of an entire blade. This makes it much cheaper to use inserts in the long run than standard blades.
Each insert can usually be rotated and has four sharp edges, meaning you can simply unscrew it, turn it 90 degrees, and lock into place again. They don’t need to be adjusted either, just like disposable blades.
In addition, shelix cutterheads are also much quieter than normal blades. This is a big bonus especially on these DeWalt planers, because they are quite noisy. Any reduction in sound makes them much more comfortable to use.
Finally, because of the angle and spiral layout of shelix cutterheads, they also result in a much better finish quality. They are especially good at preventing tearout on figured woods with difficult grain. Take a look at the video below to see how effective it is:
A Shelix Cutterhead upgrade is available on all three machines. It is a bit more common and easier to acquire for the DW735, however. We’ve added a few links below to places that sell them.

No idea why the DW734 & DW735 are not available in Europe just doesn’t make any sense at all! as DeWalt would make a killing selling these over here.
I’ve emailed DeWalt UK & asked them why they’re not available, but to date no reply!
However, there is a company who imports the DW735 into the UK, but the cost to purchase it in the UK will make your eyes water! Apart from the cost, there is another problem!
Problem 1. The imported DW735 is 120V, & in Europe the standard voltage is 240V!, it is possible to buy a transformer to drop the voltage down to 110V, but as the voltage is slightly lower than USA spec, the DW735 won’t be running at optimum RPM.
Problem 2, Cost. In Home Depot the cost of a DW735 is currently $635.70 (GBP £483.13), purchase the imported DW735 in the UK, cost is GBP £875.40 (USD $1146.77. An increase of £392.24 or $513.83) Told you it’ll make your eyes water!!!! costs based on the current exchange rate of £1.00 = $1.31.
I would dearly want to have a DW735 to replace my ageing Rexon planer/thicknesser, but as a “hobby” woodworker I simply cannot justify the UK imported cost.
Dewalt, you’re missing out on the sales opportunity in Europe, please, please, please get your act together & make both the DW734 & DW735 available in Europe!
Finally, as for the DW733, you can’t get one new in the UK for love nor money! there’s no new ones available, even from DeWalt UK directly, & although I’ve been looking for nearly a year now, no used ones on the market either!
I’m not anti-Dewalt, in fact, I have a 1968 DeWalt radial arm saw, a DW7492 table saw (replaced my ageing DW745), 3 Dewalt battery drills, plus my (not DeWalt) 2 trusty Shopsmith’s, a MK520 & a MK5 (upgraded to a Mk510, both complete with loads, & I mean loads of Shopsmith accessories!
Thanks for the detailed message, George! I agree that the DW735 could really be a big success in the UK and Europe. Especially now that many European woodworkers are watching American woodworking youtube channels where you see the DW735 all the time, which means they wouldn’t even have to spend a lot of money on marketing.
It would really fill the gap between hobbyist-level planers (like the 733 and 734) and the more professional ones.
I actually just moved back to Europe from the US and my DW734 is in the moving container on its way. I am a little bit concern about the RPM variance with the transformer but I was going to leave that behind. Costs of import are prohibitive for such heavy tools.
I really appreciate all the information posted here. I’m in the UK and have been searching everywhere for a DeWalt planer, preferably the dw735. I now see why finding one has been so impossible. A few sites do have them listed but always out of stock. Looks like you are missing out big time in Europe DeWalt. I’ll have to go with my second choice of the Makita instead although they also seem to be as rare as hen’s teeth.
Does anyone know why DeWalt doesn’t sell the DW734 and DW735 in Europe? Really curious to know why.
It may be because it does not apparently have a NVR switch and hence fails safety standards.
Question for anyone that may know…From what I see in pictures of different manufacturers that offer helical or spiral cutterheads for 734 and 735, I can’t find any physical differences. Only thing I’ve found out is that with 734, you have to remove carbide cutters to install head…and then reattach carbide cutters.
Do you know if the 735 and 734 cutterheads are same dimensions? Is the only difference that the cutterhead with cutters attached won’t install on the 734?
Just to add to the ridiculousness of DW735 unavailability in EU, DeWalt sells this model adopted to 240V and metric units in… Russia!
It costs ~1k USD and it doesn’t accept dado stack, but it’s freely available.

Busting bolts loose on 734 butter heads can be virtually impossible; I am dealing with Dewalt but as of now am not able to use my 1 1/2 year old machine.
Cutter heads …..bad spell/grammar check!
