- In this video I tear apart two new Bauer dual-action polishers to see which version is better. The Bauer DA polishers from Harbor Freight Tools are part numbers 64528 and 64529. Plus, I compare them to the older 69924.
Here's my previous video on these DA polishers: • Teardown: New Bauer DA...
What a great video. I didn't know that HF had products that were similar but had upgrades in them. This is very helpful when making a decision on which one to buy. Thanks so much for your insight into these products otherwise we probably wouldn't have any idea about this.
Thanks
To further complicate the matter, I’ve a recent Bauer 1814e-b from Harbor Freight. The model number is 64528. However, it is just like the 64529 shown in this video.
Wow. I've been looking at polisher videos for a couple of weeks now. Yours is the easiest to watch and understand. No dance music running in the background. No sales pitches. Succinct and well edited. Thank you. I'm getting closer to finding the right polisher.
I bought my polisher before watching this video thank God I’ve purchased the best one ☝🏻
Great job. I'm always paying attention to model numbers and what they change over time.
Update, I just purchased one of these newer models. Model number 64528, I took it apart and apparently harbor freight must be listening to us. They replaced the old grease with some blue high quality grease, now the commentator is resin to prevent problems with wiring from vibration and the circuit board with the speed control is that has also been dipped in resin
Great review. You make the choice easy. 64529 on sale for $59, or $79 with 20% off.
Anyone fill spending a little more is necessary. For me, I probably use it twice a year. Hard to justify spending more.
Another great video. Keep up the good work TT, you just keep getting better and better!
Thanks for the kind words and thanks for watching.
i just have to say, as a Mech eng student, your channel is literally a godsend. thank you, you have no idea.
Watching videos like this makes be wonder about the product development, procurement, testing/quality control group at Harbor freight (if they have them). I understand building things to a price point but with this hard push to bring better tools to the market place, going cheap doesn't set much confidence in the buyer. Especially now that some of their prices are creeping closer to other name brands.
I love that you’re doing this. It has always frustrated me that I have to unbox everything I buy from there in the store to see which looks like the better item number. That is, if I haven’t watched a video like this, of course. It usually leads to getting looked at like I’m trying to steal or something crazy like that. It’s a bummer.
Thanks for the info I got the 64528 with out knowing their where 2 model numbers HarborFreight didn’t wanna exchange at first cause they said it was the same tool just different model number but finally I managed to get a 64529 thank you for the great info 👍👍👍
Great video. Now I know which one to go with. This is one thing I've never liked Harbor Freight doing---having all those item numbers where you have to really look over every tool before you buy. But it also sucks because unless there is a current video showing someone like yourself tearing down a tool, people aren't able to always make the best decision just at face value. With some items it doesn't really matter much, but if we're going to spend more money on power tools, it can be night and day. These videos are really good because there are still a lot of people who don't know that Harbor Freight's different item numbers can mean significant difference in a tool.
Totally Agree!
Time is money, if you spend less money you'll need to spend more time to ensure you're getting what you need. Could throw a couple hundred dollars more at a product and get closer to perfection than having to scour reviews to find out which "cheaper" machine is worth getting. At least that's how I see things.
Best tool reviewer on YT... Period.
Thanks for the kind words.
I am glad I watched this before buying mine, the store near me had both part numbers I would never have known what the difference was.....needless to say I bought the 64529 even though they were in different parts of the store....
I can only assume the next video you will be Frankenstein-ing all the the best bits together into a custom Tool Teardowns edition Bauer polisher!
Thanks for the great videos. The -29's are a bit harder to come by - near me at least. I liked the feel of the -28 in the hand a bit better due to it's slimmer body and quality chord, but ultimately went with the -29 due to complaints on vibration. Packed it with synthetic grease and it is super quiet and smooth.
Ha! That Frankenstein thing is a funny idea.
The multiple part number for "same" product is aggravating.
A tear down is sometimes the only way to know the important difference.
They don't have the same part number.
Awesome tear down! Also noticed the pinions were attached differently too.
I have the old one and added a 25' better cord and changed the grease to Mobil 1 and it has been top-notch for the past 3+ years. Not enough differences for me to make a change to the 64529.
Yeah. I agree that it's probably not worth upgrading to the Bauer from the older model.
Keep up the great content brother👍🏻
Thanks for the kind words.
Its on sale now until Oct 14 / 2021 for $59.99 at Harbor Freight! Yes, they still carry both models. I ended up going with the 28 1.) higher opm 2.)better feel in my hands 3.)less vibration
Just got a 529 for 49.99.. was only 2 only the shelf left 1 528 and 1 529.. thank god I got the 529, just powered her on and nice smooth and quiet running.. thanks for helping decide..
How did you get it so cheap? It’s over 100 dollars at my store.
I didn’t watch this since I have no use of a polisher.
However you get a supportive thumbs up anyway 😁
Kudos. Excellent presentation. I could even understand the lingo ☺
What I dont understand is that the 529 is the predecessor to the 528. Chronologically, it's backward. You're not throwing most of us off, and we dont always want the newest version. Keep it simple HF, and keep the item #'s in order by design change date... please... Thanks for sharing. Really like the format of this video. Concise and efficient. Well done. Subbed. Will be watching many more. EDITED: Scratch the section where i was confused with the design date and item # order. So, HF went back to an older design (for the 529) to fix issues with a near complete product change of the 528. Cutting corners doesn't always work.
Thanks! Nicely said. I got a 528 but havent used it. For under 100. I consider it a write off in my long list of write offs.
There is another older Chicago Electric DA that is very similar to the 64528, I have it.
UPDATE TO MY PREVIOUS COMMENT... It appears that I must have gotten the 64529 internals inside the 64528 model what I didn't notice earlier is mine also has the older style fan as well and the older style gearhead as well.
There is a new version badged 64528.
It looks like the 64529 in this video.
Can confirm this. Mine says it’s a 64528 on the box and tool. However, it’s identical to the 64529 presented here.
I'm not convinced HF has multiple versions of the same model across their inventory because they choose to make cost cuts or make improvements. The tools that have multiple versions tend to be really popular tools, so it wouldn't surprise me if they commonly switch suppliers to keep their inventory full with no lapses, or they have suppliers sometimes pullout and are forced to go shopping elsewhere to continue that model.
I also suspect they could be using multiple suppliers to simply maintain stock, but there are significant differences between the tools those suppliers are making.
Well done video! Very useful.
I think I'd swap the cord on the -29 for one like the -28 and call it good.
I worked for years as a tool repair technician and it would be nice if we could meld the strong points of the three into one but, I think with the aforementioned cord swap (don't try it if you don't know what you're doing, there are plenty if tool repair places that would swap a cord for you) you'd be pretty good to go.
I mention this for the reasons he stated in the video, durability, flexibility length and (the -29 has a 10' cord but, especially if you live in a colder area) the rubber is just superior. Bit it's just my OCD tool-tech nerdism kicking in. The standard cord will work just fine. Until it doesn't, then get a better, rubber one.
A similar kind of surprising variation is in the U.S. General tool cabinets. I have the 44in, 26in, and 15in base cabinets, and the 44 and 15 are of heavier gauge steel and generally better made than the 26. It's not that the 26 is 'bad', it's just not as good as the other two, which I'm confident were made in the same factory, whereas I'm even more sure the 26 was made by a different supplier. I got the 26 and 15 at the same time, and in green, and the colors don't match, either. It's only apparent when they're very close together, but there's a difference. I don't regret the purchases, but I expected them to be three peas from the same pod.
Excellent Review.
Thank you for all the details. I have the Chicago Electric and am looking into the new Bauer long throw polisher. I would love to see you do a video on that and get your thoughts.
The 4.25:1 ratio is a "lower" gear ratio than 3.5:1, giving more torque. You said in your video that it was a higher ratio, which is incorrect. Overall great video, very informative, love to see these teardowns. Keep up the good work.
So you think 3.5 is higher than 4.25?
@@GertTown Yes. It is what is referred to as a "taller" or higher gear ratio, providing less mechanical advantage than a lower gear ratio which is a numerically higher number. The higher the first number, the "lower" the gear ratio is, because of the greater mechanical advantage it provides.
@@GertTown It seems counterintuitive, but it's similar to the gauge system for sheetmetal and wiring, where the smaller the number the larger the gauge, like how a 16 gauge wire is substantially smaller than a 2 gauge wire (the larger the number, the smaller the wire) Gear reduction ratios are like that.
you and real tool reviews are really good. you and AvE deff rock
Does changing the Grease on the 529 make it run smoother?
I've always wondered why harbor freight does this? I believe the Chicago electric version had a couple part numbers as well.
I can’t find the 64529 on their website anymore I just saw it a few days back wow
Good information as im looking to purchase an inexpensive polisher... Thanks
HF did the same thing with the previous Chicago models, one was good, and one was not. Both were the same price. The new 64529 looks interesting if it has more torque as ALL these 8mm throw DA polishers can stall (stop rotation) when going over edges. How's the noise and vibration with the new 64529? Great review!
I got 64528 on sale for $49 today and I'm going to use it twice a year for buffing so I'm not concern with longevity. For professional use a more expensive brand is recommended.
I got an 64528 on sale for $34.99. The interesting thing is... it’s identical to the 64529 shown in this video. You may have a 64529 and not even know it!
Wow very good video a lot of difference
Do you think that is possible insulate the wires with an epoxy by our self?
That's an interesting question, but I probably wouldn't try it.
So what about the 62862?
Interesting that HF still lists the 69924 on the coupon for the Bauer.
Your back!! Awesome let’s see this... I’ll leave a comment once I’m done
I like how you do the tools we done use on the regular so we buy cheaper. And you really help us get the best for our money. You are like the smart nerdy lovechild of ave and den of tools.
Love your videos. Will you be comparing the new 6inch 7.5 amp sku: 56367?
Was just about to ask the same question.
I have a 64528 and it looks identical to the 64529 you have with the fatter back side.
Epic review. Subscribed!! 👍🏻
The 528 has a nicer fan compared to the other 2
I just got off the Harbor Freight website. A search for the 64529 returned no results. Only one that came back was the 64528
They do that sometimes by only having one listing for an item, even if there is more than one part number available.
Currently what is the best price to performance polisher on the market. Don’t mind spending a little just don’t want to for nothing.
I have the 64528, can I get a 3 inch backing plate for it? Will anything work on it?
I want to use it to sand/polish headlights.
The 529 is almost identical to the grey harbor freight generic
Mine says 64528 on the side but the body is the 64529
Same here. Can confirm the new 64528 looks identical to the 64529 presented here. Haven’t done a tear down to compare the internals.
Is this the Polisher/Sander?
So which one came out first? That's the one I have
Where did you get the 64529? I can only find the "528" locally and on their website?
How does the gear ratio effect the torque/stalling of the unit? I would think a higher gear ratio on the "528" would mean you could theoretically spin it faster (in both orbits and rip'ems)? I can't imagine needing a ton of torque when most of the time the machine and polish/compound should be doing most of the work, no? Maybe do a comparison between the 3 on the orbits/RPM's and how easy each one is to stall?
I just went to my local store. The website doesn't always show the different part numbers.
@@ToolTeardowns thanks, I'll have to go to the local stores around here. Any idea on how the torque compares between the 3 vs the gear ratio and the machine stalling? is lower or higher better for the gear ratio? seems to me like a higher ratio would spin it faster, but with the possibility of having it stall out easier?
Is the 21 mm long throw built about the same as the one on the right?
Hi, 2 questions, 1st I can't even find the 64529 on the HF website ? Doesn't come up. And my old Chicago electric polisher is binding up when I put pressure on it. Any idea what I can do to fix that ? Could it just need to be re-greased ? Thanks !!
Sometimes HF doesn't put all the versions of a tool on their website. If you look on the coupons you'll see it includes the 64529 number.
I'm not sure about your stalling issue.
@@ToolTeardowns ok I do see it on the coupon. I guess Ill have to drive to the store. The nearest is 45 mins but I don't wanna get the same as I got last time. It didn't last very long. Thanks for the reply !!
Do they still make fhe 64529
Do a video on how to pimp
your polishers
If I decided to go with HF Bauer DA, how could I get the 64529 model that seems much better in this video than the 64528? Should I just go into the store and tear the shelf apart looking for the model numbers? lol Any help would be appreciated! I have the Chicago Tools brand Rotary polisher that is ok for the work that I do...but with the DA Polisher, its something I am on the fence about. I was going to just get the new Griot's 9 and not worry about the HF models, but there are some power supply issues currently with their first round G9 model.
That is why I wouldn't mind going with the HF 64529 for now until Griot's gets their issues together with their early models.
You just have to go to the store and check the part numbers on the boxes.
@@ToolTeardowns I was just looking on their website and it appears those listed models are the 64528 only. I will take your advice and just go to the store and see what they have...I will also tell a member of their staff about the model difference, maybe they can keep an eye out for the 64529 if one comes in with their stock. People at my location are all very nice so should not be a problem.
The website doesn't always show all the different model numbers. Both numbers are listed on the coupon.
@@passinthru6457 I am going to do the same thing then tomorrow...Awesome you were able to get the better model! It's cool to hear that!
Great video and information my friend! Keep up your videos, very helpful!
Just wondering if you planned on doing a teardown of the earthquake xt cordless grinder?
Not at the moment. It's a good suggestion, though.
Pick 529.
Have you ever done the dewalt/makita/Milwaukee polishers? Or even the maxshine? If not and I buy one would you be interested in coordinating I can film in 4K and take still shots etc at your direction
Rubber over mold is not an upgrade.
Did they get rid of the 64529 ?
No, I don't think so. They sometimes don't show every part number on the website, but that part number is still listed on the coupons.
I bought a drill master heat gun from HF...went to use for installing pex fittings....amyway freaking thing started smoking as soon as we turned it on....even though it smoked we used it to finish the job lol. So we finished. Let it totally cool off...turned it back....still smokes. What a pos lol
I belive drill masters being discounted for warrior brand.
Thanks. Very detailed. Doesn't mean anything as you have no empirical data to back any of your assumptions. None of these polishers are worth worrying about. Buy and use. Don't expect professional quality. Great video though.
10% tax , ouch
Reverse engineering to its best
Do yourself a big favor don’t buy a DA Polisher at Harbor Freight. It’s not going to last or perform well. They vibrate horribly bad and you will have numb hands not long after you start running the machine. They’re plenty of inexspensive entry level DA polishers out there. Keep looking save your money and get a good one. Spend your money on a tool that you’ll enjoy using and will last longer than one project.
Bring our factories back to the USA 🇺🇸
Slowly happening. Our reliance on outsourcing has led to a national security risk
Good afternoon Sir. We think your channel is very interesting! Would you mind to share your business email with us?
This is a stupid comparison since you can't pick which model number you get. It's usually which one the store carries (They usually carry one or the other but not both) or which one gets sent to you when you order online. You can't speficically get one over the other. Useless comparison.
My local stores often have both part numbers.
Sure you can if you go into the store.
Weeee Ewwww he looks just like Buddy Holly.
Hey grandpa can I borrow your old polisher this hf one 💩
Do you have a Patreon? Is totally donate to help fund more of your videos!
Thanks for the offer. I don't have a Patreon because I don't feel I can produce enough content right now to justify asking people for support. If I'm less busy in the future and can produce more videos I might start a Patreon.
