I’m about to invest in some “prosumer” level 18V power tools, e.g. Makita, Dewalt, Metabo, etc. The general consensus appears to be that they’re all more or less equal and it doesn’t matter much which brand one goes with, but a few years ago I developed tinnitus which has made me more sensitive to high frequency sounds. And having tested a few cordless drill drivers at various hardware stores I can definitely tell they’re not equal when it comes to what the noise sounds like, even if they measure similarly in sound pressure level.
Currently I have a Ryobi 18V brushless that I measure to 83-84 dB© at 1m which makes it pretty loud, and it also has a quite a quite high pitched sound which makes it worse. Looking at a spectrogram from a calibrated measurement mic there’s a pretty clear peak at 6kHz. The drill drivers I’ve been looking at all have a rated sound pressure level (Lp) around 76 dB so they should already be noticeably less loud, but I’m hoping to find one without those high frequencies if possible.
I’ve been able to test a few drills in person and got some initial impressions. Unfortunately the local hardware stores have a pretty limited selection of brands, they don’t have all models in the store, and you usually have to bother the staff if you want to try something with batteries in it. At first I thought I could remember my subjective opinion of different drivers, but when I later got the opportunity to re-compare two of them head to head I realised I have really bad memory…
Head-to-head comparisons that I’ve done:
Makita DDF484 vs Dewalt DCD791: The Makita has a very high frequency whine, kind of like dentist’s drill. The Dewalt is probably just as loud, but a little lower pitch making the noise slightly more tolerable, while still not great.
Makita DDF484 vs 485 vs 486: When it comes to high pitched noise, 484 was worst, followed by 485, and the 486 was most tolerable.
Dewalt DCD791 vs DC800: The 800 had a more high pitched noise than the 791, once again reminding me of the dentist’s drill.
Not compared with anything, so only subjective impression:
Hikoki (a.k.a. Metabo HPT in USA) DV18DD and Dewalt DCD777: Smaller and weaker tools but much more quiet than everything else. If I were going to buy 2 drill drivers I’d probably get something like these plus one larger for heavier work.
Metabo (the made in Germany, non-HPT, brand) DS 18 LT BL: Only had a quick try with this machine but without having anything to compare it with I thought it sounded pretty reasonably tolerable. There’s a version with quick change chucks, unfortunately only the smaller (L) and larger (LTX) models have offset and angle chucks for some reason but that’s a feature I would really like to have.
Anyone compared Milwaukee to other brands with respect to noise? The only store I found that sells them said they didn’t have any charged batteries so I couldn’t try any.
Not exactly sure what I’m expecting from this post, since the question is so subjective… Perhaps someone with experience of multiple cordless drill drivers could share their opinion? Or someone else with a similar aversion to high pitched noises could say if they found any tool that they’re happy with?
I dunno dude. Maybe ear plugs. What kind of work do you do?
It’s just random work in and around the house. Some times I needed a more powerful drill driver was when laying bamboo flooring (had to be screwed down) and replacing bargeboards. Projects planned for the future include removing an exterior door and rebuilding the wall, and at some point to build a new kitchen. Occasionally I have some hobby project that requires lighter drilling, e.g. building subwoofers or keyboards, or simple stuff around the house like hanging stuff on the walls or ceiling. We live in a wooden house nowadays so no concrete drilling.
I use ear protection for bigger projects, but if I didn’t have to if I’m just going to do something quick, like installing blinders in a window or hanging a painting. My first drill, a massive corded Bosch, had much less of an ear-piercing sound that the Ryobi that I have now.
For drills not so sure, but for impact Milwaukee has the surge which is still pretty powerful but a lot more quiet than their fuel version. Anytime someone uses mine they ask if it’s broken because it’s so quiet.

I remember a reddit post on home improvement about quiet drills relating to a neighbor being annoyed. The guy was kinda being too accommodating for all hours of the day.
I gotta say at least your reason is more… I dunno…reasonable ?
Pop by a Lowe’s give the Milwaukee M18 surge a try I’ve heard good things about what people haven’t heard using it.
Unfortunately (?) I live en Europe so no Lowe’s here… The only store that sell Milwaukee here is almost an hour’s drive away, and it’s a pro store so their opening hours is something like 7:30 - 16:30 Monday to Friday. Once I took a half day off to go there, but Milwaukee was the only brand I couldn’t test because they didn’t have any batteries available :/
I don’t know. The big impact drills are loud AF. I actually like using my non-impact one more because its so much quieter.
https://www.cdc.gov/niosh/topics/noise/noise_levels.html check this out quick glance seems like the excel sheet could be handy
Thanks, though it seems like the list contains corded tools and none of the models I’ve been considering. It also looks like the sheet only lists sound power level, i.e. something like overall loudness. While lower sound in general is of course good, what I’m trying to find is a drill driver that doesn’t have as high pitched sound as most 18V tools do. For example both DCD791 and DDF484 have a listed SPL of 76 dBA, but I found the noise from the DDF484 to be more annoying due to it having higher frequency.
