In the video, I mentioned that the sound level was about 5 dB quieter, and some viewers have pointed out that this might not seem significant at first glance. However, the decibel (dB) scale is logarithmic, not linear, meaning that changes in decibels represent exponential changes in perceived loudness. Here's a quick explanation: - **Logarithmic Scale:** Every 10 dB increase represents a tenfold increase in sound intensity. This means that an increase of 10 dB sounds about twice as loud to the human ear. - **3 dB Rule:** A change of 3 dB is roughly a doubling or halving of sound intensity. So, a reduction of 3 dB makes a sound about half as intense, though it may not seem exactly half as loud. - **5 dB Reduction:** A reduction of 4-5 dB is significant because it represents more than a 50% reduction in sound intensity. The planer is now noticeably quieter, improving comfort and reducing noise exposure during use. Installation: If you’re following this video as a guide then please make sure to remove the blades from your original cutter head before beginning. Also some thickeners have a metal latch that prevents the cutter from spinning, this also needs to be removed before removing the original cutter head.
Put simply the dB is the the power of the sound. For every 3dB the power doubles. Your meter indicated a reduction of 3 or 4 dB therefore the sound level was reduced by least 50%
• 3dB = Double the power. • 6dB = Double the amplitude, quadruple the power. • 10dB = Approximately double the perceived loudness. (sound designer here interested in woodworking ;)
I just did this upgrade last week with the same cutter. I am very happy with the results. Today I planed several boards and no snipe and smooth as glass finish. The planer is much quieter and dust collection is 100% better. Also the actual upgrade was not complicated at all. I just watched the video on their web site and followed it step by step.
I didn’t think to test the dust extraction because I dont often use it and just sweep up afterwards! And glad to hear you found the installation easy, you’re obviously more skilled at these things than me!
Hello! I bought this shaft and I have to say that when planing pine or other soft wood, the quality is not good! My regular HSS18 knives in the DeWalt DW733 cut soft wood much better and the machine doesn't get as tired! Be careful because with longer work with this shaft, the motor may burn out due to the increased load, and the DeWalt warranty does not cover this due to the replacement of the shaft! I am returning my shaft. Quite disappointed 😫😫
Great review. Very objective. With regards to the sound reduction, I'd say that the motor on the machine will always have the same sound level whatever cutter head you choose. The difference is noticeable when the knifes hit the wood. That's where the sound difference is and that level was dramatically lower on the helix.
Perceived loudness doubles with every 3dB increase. It looks like you got a good 3-4 dB reduction so, their claim of a 50% reduction is valid. I am watching your vid this morning because I'm going to install my findbuytool cutterhead this morning. Excellent information!
@sumeraybuilds the difference is stunning, man. The install went smoothly, and the planer is producing gorgeous wood. So far I've run mahogany, maple, cypress, pine, oak, and padauk. All came out smooth as a baby's backside. Thanks again.
@@sumeraybuilds Thanks. I paid more for the cutterhead than I did for the planer. It was good before, but now it's even better. Now I gotta hook up the digital Wixey gauge thingie. It's always a new opportunity.
Excellent video as always. I like how honest you are about what you do know and what you are new to. I don't know that decimals used a logarithmic scale. That changes everything! Keep up the great work, excellent channel, excellent content
The results are superb. I would have lost most of the bolts though in the disassembly phase. Though following your instructions would have definitely helped. Great video.
Check out my pinned comment about installing. Make sure to remove the blades as step 1 and the little metal latch that stops the cutter spinning. Good luck!
speaking of the noise.. depends on the sound spectrum. The meter most likely measure the overall sound volume no matter the frequency, and so while tho bottom frequency noise has been reduced the high pitch noise has not, therefore the level is almost identical. If you narrow the sound meter to a lower bound of the frequencies you would get quite different result.
Quick and simple review. Nice to see that there have finally come a helical cutter head for the 733, and not only for the 735. Sadly it can only be bought in UK, so no shipping to rest of EU, without heavy customs and time penalty. Reguarding your comment of "if only used for pallets" is espacially where this is justified, because of the frequent hitting of a consealed nail.
Great review - I think with regards to the noise you’re right. Regardless of the “decibels” the sound with the helical head is a much more pleasant pitch and doesn’t seem to vibrate my eardrums at the computer as much 😂
Thanks Jack, ye just saved me a ton o pennies. My 2 #5 bench planes give me a chance to zen out as I flatten the pallet wood, which is 98% of my material. Take care & stay safe.
You Britts make me laugh, in a good way. Very entertaining for sure and greatly informative. Right good vidoe mate! It's definitely a process to replace the head. This is the first time I've seen it done. Your basically tearing the whole thing down... I think you're Db meter needs calibration, there's a more noticeable difference than what that meters displaying. There's apps for free... maybe use one to cali the other.... thanks again very good video.
@@sumeraybuilds well that's our petty human nature at work. It's been instilled upon us that more is better. After all Spinal Tap had amplifiers that went to ELEVEN!!! 😂 Have a great weekend mate!
Decibels are logarithmic, meaning it’s not like 50 decibels is half as loud as 100db, a 10db reduction roughly equates to 50% quieter. So that claim is very nearly accurate. Too many variables to count, you have the time of day, type of wood, moisture content, heat of the blades, etc. For reference a 5db increase in noise is noticeable to the human ear as being louder. A 10db increase is perceived by the human ear to be roughly twice as loud. Hope this helps
Nice video! Decibel scale is logarithmic, which makes it a total pain in the arse to understand. The quietest audible sound (perceived near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB
the decibel meter doesn’t do it justice, maybe inside a shop it’s louder. but it definitely turns the sounds from a noise I hate into a soft and gentle sound similar to the wind
Decibels interpretantion should consider that the energy measured doubles every 3 points. So your perception is correct, you hear far less nice but the measurements read a few points of difference, those points are a big deal. Great video BTW.
Were you aware of the Axminster professional thicknesser when you bought the Dewalt? Just curious why you decided not to get it as it as a helical cutter head as standard and go through all this work instead.
hammering the head of the shaft while installing the new head would damage the bearings. You must hammer only the outer ring of the bearings in this setup by using a thick walled pipe to sit on the outer ring
From my research, it seems that this upgrade stresses the motor of this planer as it's somewhat underpowered. Some manufacturers produce helical cutters with only 2 helices to protect the motor. Would love to see an update after a while 👍
I did read a couple of posts saying this, but my testing hasn’t indicated anything like that in the results… yet. If anything changes I’ll do an update vid.
Jack take it you no link isnt working?? Do you no if they sell them for multiple plainers?? The helical head looks like you could just use carbide cutters for wood turning tools 🤔🏴👍
No tear out, I call BS, put a piece of New Guinea rose wood any direction and get back to me with no tear out 😂 that stuff is lovely to use but is a challenge to work with.
If I had some I would test it! I agree that saying 'no tear' is likley over promosing when you consider all wood types, however from my tests it did an excellent job!
I think inover the past 25-30 years, I would have needed a thicknesse maybe two or three times at most. I have an electric plane, but usually opt for my trusty Stanley bought in the 1970's for just £5 or so, and it is just as sharp now thanks to diamond stones.

Was just going to point out that decibel ratings are not linear and are logarithmic, so the actual "loudness" goes up fast with just a few numbers.
Thanks for explaining 🙏 I’m going to add a pinned comment explaining this
• 3dB = Double the power.
• 6dB = Double the amplitude, quadruple the power.
• 10dB = Approximately double the perceived loudness.

A difference of 6db is roughly double , so I'd say their marketing material is correct
Thanks for explaining! Makes sense… I think 🤔
@@sumeraybuilds think of it this was. 20dB is twice as loud as 10dB and 100dB is twice as loud as 90dB.
Is helical cutter head suitable for all types of DW733? I own type 11, there is type 2 too.
It should say on the FindBuyTool website
I broke the belt doing it can you help me find a replacement if that ok thanks
You can order spare parts online, there’s a few websites that let you order the exact part you need.

Yes I’ll look into it, not sure what’s going on. Yes they sell all the helical head for many so it’s worth checking out their site. 👍
@@sumeraybuilds no worries I'll have a look cheers mate 🏴👍
-3dB is 50% sound energy reduction. So the claim is roughly correct based on your reading.
I realise that now 😳
As I can't get your link to work, how much is the upgrade? Thanks
It’s £255 and £20 off with that discount code in the description. I’ll look into the link not working thanks 🙏
Thank you for the info & the video 👍
Yes but how much is the replacement?
It’s £255, I do show it at the start of the video 😅
nice
Thanks 🙏

Fair enough! 😂
Not worth the 5-7 hundred dollars they cost i only paid $650 for the machine
It’s £250 for the new cutterhead!
3dB is equivalent to 50% in apparent volume
I had no idea that’s how it worked at the time of making this video 😅
