Teardown Review: New Bauer Long-Throw DA Polisher from Harbor Freight

[@bronxhouse00]

Wow. This is a step up in product reviewing. The tear down for quality and parts inspection is superb. As an Engineer these are the type of detail reviews I look for. Not just usage and effectiveness but design and build quality is just as important.

[@rauladame2105]

Your post helped me. I purchased the Bauer and tried it out of the box. It worked fine, it was loud and I did notice the vibration. I tore open the gear housing, cleaned out the grease and added new good quality grease. The noise and vibration were greatly reduced! Your post break down helped me greatly on my purchase. Thank you very much.

[@kellytennant9348]

Superb presentation! No obtrusive background music. Succinct and to the point. Good editing. Good summary. Thank you.

[@nlsnivan]

Amazingly detailed review. Your knowledge of materials, parts and their purpose is astonishing.

[@conductorjohnmthtrains2239]

I just purchased this bad boy & cut & buffed my camaro this morning. Are you kidding me! Black paint looks like a pro buffed my black RS. What a nice buffer for the first timer, HIGHLY RECOMMEND. No vibration no noisy gear sound

[@MarkusKleis]

The distinction between 8MM and 20MM throw is substantial. It's a totally different tool - that longer throw will substantially increase cut and reduce work time for defect removal.

[@josephthomas2226]

one of the best product reviews I have ever seen. Very thorough. currently the prices are $70 for the 5.7 amp and $90 for the 7.5. I would spend the extra $20..

[@tonycook8348]

Thanks for the great review. I was trying to decide between the two HF Bauer polishers. After watching numberous KZbin videos, I chose the newer Bauer with the 20mm throw. I haven't used it yet, but the ramping speed control, lower vibration, longer and rubber coated cord, ease of brush replacement, and the rat tail trigger handle sold me on spending the extra money...all that, and the fact that I still had $180 left on my HF gift card from the class action suit. I was glad to see they used more/different grease in the gear box on this model, without me having to tear it down to check before even using it. Can't wait to get started using it for paint correction and polishing, after deep washing and claying my 1993 red Accord (212k) and 2003 black Expedition (50k)!!

[@joshlampe3458]

Just like you, since I already have the 1st gen polisher, I'm not justified in buying another one for $100. For those who feel they need more performance out of your polisher, I recommend spending the money on some good microfiber cutting pads. I don't need anything more aggressive than those, they cut as fast as I want to---so there is little benefit in the long throw for me. Great video as always TT!

[@ToolTeardowns]

Good suggestion on the pads.

[@anthonyfontaine2373]

Excellent review! As a part-time detailer I was interested in purchasing the newer model and have a similar older model you explained in detail the differences but your conclusion was excellent as well as it will justify me purchasing the newer model when it goes on sale Good work bud thank you for your time. Looking forward for the next video 🙂

[@banette36]

Yes I would ! And I did ! I did not know I could fine tune the counter .. thank you for your very professional video !!

[@dillon3355]

You should do a New tear down and comparison of a current Bauer vs. A Rupes Mark iii. I think a ton of people would really like to see if Rupes is the premium product they claim.

[@Michael-ri2eh]

Yes,it is worth the money I have replaced the grease and backing plate to a five inch runs smooth

[@jimm6339]

Thanks for doing these reviews of the HF polishers. I fall in the same group as you. Would only need to use it once or twice a year so I think I am going to get one of the less expensive HF polishers as it would be good enough for me

Very nice video, thank you. Because I have a boat and two cars to maintain I opted for the newer tool. The extra $ didn't dent my budget and I appreciate less vibration. I also use this tool on smaller projects and enjoy the ergonomics over the older tool.

[@djsavage2421]

I truly appreciate your review I am going forward the newer one because this is my first polisher and I agree with you if I already had one I would not spend the extra money but being that I’m starting from scratch it’s gonna be worth it for me and also being that I’ve never done this before so that slow start can you give me a little better sense of control in set my mind at ease and I’m not gonna burn through my clear.

[@GonzoZener]

Great break down. New one seems like great value compared to other higher priced brands with similar design. I think one should also take into account available accessories that will work with new model.

[@foxwood67]

I have an older one and am happy with it. When replacing I would upgrade for the small added features. Happy holidays to you.

[@alfredomarquez9777]

I would not say that there is "just a little improvement" in the newer one, because the "Throw" of 20 mm versus 8 mm makes it MUCH more powerful and efficient at polishing a rough, just applied paint job. (Perhaps the older one is acceptable for only applying wax or removing fine blemishes, but little else).

[@howardjones695]

i like the review how much would it cost to apply epoxy yourself to all those components? about $5 or so? it looks like it would be easy to do yourself and save over higher end. maybe replace any low quality bearings too?

[@fasteddys906]

Thank you for tearing this down love your videos

[@BadRonald1]

Just seen your page I will subscribe I like that there is no music and that you disassemble to really see the insides of the tool. Just wish you could've done some more review on some other DA Polishers. Good job

[@aaronpowell4885]

Thanks for another great review! I've been pleased with my trusty Chicago electric da, tho last year I did have to reattach a wire that came out of one brush holder terminal. That said I'll keep the one I have until it dies, but when it does I'll strongly consider the bauer long throw.

Nice Video, my Porter Cable 7424XP just died and I'm looking for a replacement.

[@ruthnoya8424]

Did you buy this new one?

[@theodorehesson6134]

Your review sold me on this product for home use. I have a Porter Cable 7424XP that gives me excellent results, but since developing arthritis in my hands the case diameter, vibration and on/off give me some difficulty. Looking forward to what appears to be a more ergonomic machine. Have also been eyeing the G9; since this is low usage, and a trial for me will give the Bauer a go.

[@account2s]

You can buy some anti-vibration gloves. After I got my da and a few uses my hands were very tngly. The gloves almost cut down that feeling. I have a Meguiars polisher. I will not polish without the gloves now

[@bcarlson0705]

I have the upgraded Bauer polisher and use it several times a month. I've used it over a couple of years now and finally burned it out. Are replacement parts available? Or should I just replace the whole tool?

[@neutrodyne]

You did a nice job on your video. I never use one but if I was buying one I would go for the better one since it would do the job quicker.

Thank you for this video, I've had my eye on this machine. However, the Griots G9 right now is just $20 more. If it was your money which would you buy?

[@carl3233]

g9 all the way why waste your hard earned money on junk.

[@mrhonda1]

@@carl3233 I had the G9 in my virtual cart since a website had it on sale for $120 and that price had me leaning in that direction. The sale countdown timer was at 5 days when I put it in the cart. I was doing a little more research and started to see several reports of the G9 quitting in the middle of a job and not starting back up. I read that there is a "new" version of the G9 that might correct those issues so I was waiting until the end of the sale in the hopes of getting the newest inventory. However, I checked back in on my cart and the price was back up to $150 before the end of the sale. I contacted the company's website and it turns out that Griots told them that they can't have it on sale so they had to put the price back up without notice. My only other experience with Griots was an overpriced bottle of garbage car wash so I wasn't a fan to begin with but we considering the new machine solely on the sale price. The other deterrent was the fact that the G9 doesn't have a soft start. Who designs an all new machine from the ground up and doesn't even put in a soft start? Even Bauer did that. I may or may not get the Bauer but I'm definitely not giving my money to Griots anymore. Maybe a Maxshine after I do a little more research.

[@davidstill754]

Nice tear down review. I do wish you had taken it a step further and tested the noise level. Some of these HF buffers are extremely noisy. Would you say that the newer one is any less noisy/louder than the older version?

[@lacro5686]

Does the backing plate have the 5/16" male thread the same as the old model? Also, would a 5" backing plate (with cooling holes) fit in place of the 6" I wish they had done a 15mm throw instead of the more aggressive 20mm throw, and made it a 5" polisher instead of 6"

[@KBzPTGT]

Why not just change out the backing plate/pad for a 5"?

[@lacro5686]

@@KBzPTGT That's basically what I am asking. Does the polisher have the conventional 5/16" male thread stud on the backing plate so a 5" BP will fit?

[@jamessilverman4887]

I bought the new tool you have reviewed. I did not know the differences between rotary and DA. I am about to reduce gross overbuildup of gelcoat epoxy resin I applied to the hull of my boat with wet sanding. I assume this tool will cut deeply faster and more evenly than rotary if I am learning the uses, but it not please correct me. Thank you.

[@ruthnoya8424]

Rotary buffers cut much faster than dual action polishers. I worked in rv and boat yards in the past and all they used were Rotary buffers.

[@1pcfred]

I don't polish much but I do like DA sanding. The old one would take common pads and discs. Can the new one?

The new polisher is on sale now at Harbor Freight for $59.99! Compared to $99.99, I think it is a good value. I've been sealing my car once per year by hand and I'm thinking this tool would probably save me a lot of work. What do you think? Should I buy it?

[@jennyparker7813]

Bauer is really trying to step on board with the new long throw design at Harbor Freight that says compare to rupes. I have roots 15 mm long throw I have had other cheap dual action polishers from Harbor Freight they work I had trouble cheap rotary from there that work to but I am curious to try there new $99 long throw polisher like it might be a good Wanda keep in the box if something goes wrong with the other one

[@SlingbladeJim]

Has anyone reset the vibration adjustment screw and if so to what setting.....how many turns in or out....

[@robertbolding4182]

I have to have the new one because o will be using it as a sander and the 2.5x throw means sanding wood means two and a half times faster sanding,

[@fastbusiness]

Thanks for the review. This really shows the differences between the two models. I'm not sure I would pay more for the Bauer brand, even though it looks a little more robust.

[@1dash133]

I would have been interested in your thoughts about replacing the factory 6" backing plate with a third-party 5" backing plate. I've heard that the 5" doesn't bog down as much, vibrates less, and is easier to manipulate on curved surfaces or in tight spaces. Basically, it works better ... but is it worth the 40% to 50% cost differential? P.S. Got my answer elsewhere. It's recommended that you replace the 6" backing plate because the factory backing plate flexes too much. So, if you're going to spend the money to replace it, you might as well replace it with a 5" backing plate. (I replaced mine with a RUPES 5" backing plate, Part No. ‎980-027N. Works great!)

Thanks for putting the reviews with amazing details. A lot of us would like to have a tear-down comparison of HF 56367($110) vs Griots G9 ($150) as both of them are almost on the same price range.

[@seank8515]

That might be a little apples and oranges as the G9 is a short-throw (9mm if I remember) and Bauer 56367 is a long-throw. If you're talking build quality, it wouldn't be hard to guess that the G9 will be superior with a lifetime warranty.

[@jsmctch]

I have the GG6. Do you think this an upgrade?

[@ToolTeardowns]

Well, the Griot's polisher has an 8mm throw. The longer throw on the Bauer would be a benefit in some cases, but could also be a negative in some cases.
