Experimental ONE OF A KIND impact wrench - Does the ambition outweigh the current technology?

- Опубликовано: 14 янв 2024
- In all honesty I don't know what I was thinking. It seems like this impact wrench has been thought through. Looks like the spring in the impact mechanism is the strongest it can be without having to deal with any issues.
The claim is 520Nm, but we all know what Aliexpress claims are like. Although it does hover around the 200Nm mark, which is not bad for the price. The experimental version can even go beyond that.
It seems that with a stiffer spring in some cases the motor can not overpower the tension of the spring so you have to pull the trigger in just the right position. Is it worth the hassle?
You decide and let me know!
Original Gisam video: • GISAM from Aliexpress ...
It did end up being more of a fun and not a factual video, but as I have said I want to make tool reviews AND have fun on this channel. I hope you enjoy my ambitious but rubbish project!

Nice video! thank you for testing them!
Thank you for watching!
Super video!!! Very nice experiment!!!!
Thank you!
Cool to see this tested! So the tool was indeed somewhat limited by the spring, but the motor is definitely not torquey enough to overcome the stronger spring huh. You've kindof created the opposite of the hikoki triple hammer which skips impacts under heavy load!
Hmm, it would be interesting to try a triple hammer on this. *Grabs disproportionately large plasma welder.* I think there is some promise here, with proper high output batteries. However if I spend 50EUR on a battery why would I use it on this and not on the real thing. It was indeed interesting to get this done. Initially I felt I had achieved something and then the battery started to drain and I was drained of my achievement. Still surprising that with a full charge it can do better with the genuine Makita spring than with the Gisam spring in there. 20Nm difference is not too much of an overstatement I feel.
@@BrokeLifeEUthere's a German youtuber who tried parkside 8Ah batteries on Makita knockoffs via an adapter with good results (SiegfriedBuba). I know Makita don't want to switch to better batteries on their LXT because they're trying to push people towards 40v XGT, but they're missing the boat imo, stuck on 5Ah 18650s. Imagine the possibilities of pouch cells or even 21700s on their lxt range, I'd frankly be tempted to upgrade my whole loadout and sell what I have of Parkside and others. Their tools are maybe less powerful but more reliable and serviceable than Milwaukee and Bosch, with the exception of their hammer drills. Never paying for XGT tools though, crazy prices for marginal gains
I also wanted to do that in this video. However I thought it would become too long and burdensome to watch. Still I think there is some more exploring to do in the battery area. I saw a claimed 16Ah Makita-like battery on Aliexpress today. I think that would be fun to try out. No info on the cells used in it though.
Also, on that model, using an original makita batery helps. God job on this one!
Thank you, I don't think there was any proper insight in this video, but on the other hand it was fun to get to do this.
@@BrokeLifeEU for me it was, as, at some point, was thinking of tweak it as you did, also, it was fun explaining why was it stopping, I think that is an overcurrent protection or maybe the battery is not providing the current it needed. I am using my drillpro one only with original makita battery, as do have a couple of those...
Thank you so much! I am glad I could provide insight! I really thought it was just a fun test and no real substance. Albeit I was surprised they managed to get the most out of the impact wrench, without leaving anything on the table.
I think you should do a test to compare them using genuine batteries as they make a massive difference from using quality cells over questionable cells
For sure! Although as of this moment this video will be for sometime in the future, as I do need to set aside a budget for two new genuine Makita batteries and a charger. As I don't have any Makita batteries at all!
Would be interesting to see if this gisam (or any other dtw300 clone) with good batteries (original ones or parkside with adapter) can compete with parkside 400nm
Stay tuned! 😉
@@BrokeLifeEU waiting for the new videos! oh and of course the dtw700 chinese clone is also interesting to compare with Parkside 400nm and 1/2-converted pdssap ;)
Hello again. Regarding this topic I uploaded a video today about a ONEVAN right angle impact which I test with their battery which is a 20V 4Ah with questionable cells and the 8Ah 20V Parkside battery. It's not like the results were surprising, but still.
Looks like i won't be changing any springs.
I have the 1200nm impact wrench from gisam and its very powerful. You should definitely try it someday.
I ordered the Onevan version a couple of months ago, their 1800Nm version. First impressions are that it is a very strong impact wrench for that price.
In this case the hypothesis regarding the different springs deserved some testing. I had hopes it would end up being a good mod, unfortunately it turned out not to be so. Best case scenario on a full battery you gain 10-15Nm, but I think it will severely shorten the motor's life so it is not worth it.
@@BrokeLifeEU i think the electronics will go first, on the other hand, that board is cheap, cheap for a reson, nonetheless. Did you see how tiny that condenser is? :-) I was thinking to tweak mine also with a bigger spring but a did not know a original makita will fit. I have the drillpro one but there are somehow identical, I'm sure. I have it for two years and a half, I do use it for smaller jobs along a parkside b3 and a milwaukee gen2, still working...
@@BrokeLifeEU I'm looking forward to the review for the 1800nm.
Yes, I think had I forced a bit more the electronics on mine would have also went the way of the Dodo. Still I think they can last as long as you don't overwork them too much. I even know of a mechanic who uses one of these daily and has done for over a year without any problems. If things get tough gets out the air tools, but if possible gets by with one of these.
I bought 1200nm gisam wrench its fucking great tool for the price I’m loving it also the battery’s are long lasting
Out of the box unmodified
What were the highest NM values you got to?
For example forwards/reversed?
On a full battery and a good day also on a boot with no rust and that has just been installed. 210Nm-220Nm at most. After that it is anyones guess. It might go it or it might not it will depend on the unit. A safe guess is 200Nm at most. How long it can continue doing that is still unknown. The cells in the battery are questionable at best. The tool itself looks like it can take a beating and is capable of a bit more but the battery is the the main issue holding it back.
@@BrokeLifeEU Thanks for that :)
Are there alternative battery options with more longevity reliability?
@collegesynewave Not a problem at all! It should take a genuine Makita battery or you can just get any decent battery and use a 3D printed battery adaptor.
@@collegesynewavethere are some free 3d printing models available to make the Parkside batteries work with Makita (or wannabe-makita) tools. In my country Lidl has some promo campaigns multiple times a year selling 4h batteries for 20 euros which is awesome in my opinion. As far as I know Parkside uses Samsung cells in their batteries and if this is true then this is a great deal.
Splitt battery and load in high discharge rate cells will have more power then or use original makita battery should do same
Did you compare this original impact wrench with modified PS ..B3 or C3?
Which one is more poweful?
... Or this will be in new movie?
Do you mean the green Parkside PASSK B2 with the modified B3 and C3 or the Gisam against the B3/C3 1/2"?
@@BrokeLifeEU PDSSAP B3 conversion to 1/2"
Between the B3 PDSSAP and Gisam there will be no competition. 210Nm is easy for the Parkside and and a 50-50 shot for the Gisam. Even the green PASSK B2 brushed Parkside is a lot better at 210Nm than the Gisam.
Do you think gisam are a usable daily tool 1800nm sounds a little exaggerated
I have the 1800Nm version. I can confirm it ia nowhere bear that. But it can take off rusty bolts from a 4x4 that have nit been remived in years. So for use in cars I would say it is good enough. If you ise it with a decent battery it should be even better!
There Are this modify for parkside performance impact wrench?
Could be, as long as the new spring is roughly the right size it can be done.
Is possible found a correct spring or a spring with the same size but more long or powerful?
I can look in to it, however if Gisam managed to figure out the best spring for their impact mechanism I doubt I can improve the Parkside.
@@BrokeLifeEU However, I imagined you already showed me enough how to modify it, I think that would be enough😂👍
@@antonius3301 🤣🤣🤣 fair point! So enough with the modification videos for now!
First time I did this modification in 2020, when TopShak starts. Try to use 6Ah original Makita battery, that will be another 'mod', than you will see total difference. I tried to modified larger of wrench version with spring from DTW700, but there it was bad mod, after that spring wrench was much weaker :-\
I was actually surprised by how on the edge they managed to engineer it! I thought they would leave some room just to be sure. But it seems like they managed to fit the tightest spring thy could without scarfing on anything. I hope my video budget will allow me at some point to get to a genuine Makita battery! The spring in this case was something like 3 EUR and the anvil another 3 EUR so I wanted to see if I could get squeeze some more torque out of the Gisam for as little as possible.
@@BrokeLifeEU you need to try that clone of DTW700, that is very good wrench and with 6ah (6ah is really stronger than any other, like 5ah for example), I tried it and loose 1300Nm
I have the Onevan version! I have had it for about 2-3 months now. I don't have the time to get to it or a proper way to test it yet...I am working on it though! It does feel quite strong, not even for the price. It feels strong in general!
@@BrokeLifeEU I tried every brand of them, Kamolee is more 'smooth' and didnt cut off like gisam or onevan in that very limit situation with BL1860, but in my opinion onevan was strongest, but it cutted off in torque more than 1000Nm
For sure those things are nowhere near their torque rating. Even so I got the Onevan for something like 50EUR on sale with two batteries and a charger. It should be plenty good for any bolt or nut on a car. It's just with these Aliexpress tools the batteries charge so painfully slow that is a big discomfort for someone like me, who, can't plan out their time right.
Hello can you select all the modes. Mode 1 one LED Mode 2 Two LED & Mode 3 all three LED's.
My unit has a, weird display. Wonder if your is doing the same things.
Hello! Thank you for commenting! SO I have checked both these Gisam impacts and the LEDs behave just as you describe. They are a bit weird you are right, however since it does not have too much power I usually just set it to LARGE (max power) and leave it there. The way I read the LED indicators in forward one says SMALL and the other LARGE. Small might be for screws (using the 1/4" hex) and Large for bolts/nuts using the 1/2" drive square. I hope I am being helpful here. I don't really use these a lot.
What is more strong gisam or parkside?
In this case the Parkside. Not even close.
Интересное решение🤔, поставить пружину от оригинала...
Это была интересная идея, поэтому мне пришлось ее проверить. К сожалению, неутешительные результаты.
@@BrokeLifeEU Вы молодец 🤝 Решение поменять некоторые детали мне понравилось. Буду знать, в будущем, что детали подходят.
Спасибо! Возможно, есть источник лучше, которого я не нашел.
Like
Thank you!
I won't be doing that to mine 🤣
Good idea! Leave it as it is. I did it just to test a hypothesis.
I have the same but not Gisam, i have other generic aliexpress impact wrench and i think the battery is lower quality than yours, i cant lose any lug nuts in any car, it probably has no more than 70 NM, i am thinking about modifying the battery, ditching these crap cells and put there some Sony/Murata 25 to 30 Amps instead. I dont know if that is possible, not sure if the BMS will hold in this crap
I am not surprised I doubt for this price they have any quality control. Anything that is assembled and looks like it should is ready to be shipped most probably. It is very hit and miss buying tools from Aliexpress as you don't have a genuine return option so they'll just send you something and you have to hope for the best. Regarding the batteries I have not tested this myself, but I do see in the comments many people do say that better batteries make a difference on these.
@@BrokeLifeEU makita as uses Sony murata cells from 15 to 35 amps of discharge which means depending on the configuration (3ah, 4ah, etc ) it can deliver power bursts of up to 1300w. These cells are expensive as you can imagine, mines should not be anything close to them as the battery itself was a 12 euro option extra and with 12 euro you barely buy one or two quality high discharge cell …that’s why it can’t move any nut
Yes, although I was surprised to find that the Gisam batteries have two rows of 5 cells and that they are in fact around the 4Ah mark. They are decent for the price. Although as no warranty claim can be made on these tools a bit on the risky side. And the charging is painfully slow! @@ferfire9
Absolutely on your side on this one! It's just I was not expecting to get any sort of power at all. And it has some.
@@BrokeLifeEUyou got better luck than me. 😅 I almost can stop the impact driver with my own hands, that’s how weak it is, measured the voltage and was 19,9V.
Both brands made in china but one at least designed in germany (i think)
The Parkside is a lot more expensive and it feels better built but I guess that comes down to price. Surely Gisam could have made better moulds and smoother edges, but it would have cost more.
I bet you put a parkshit on the thumbnail to get my attention. 😆😆
hahaha You got me!!!
Stop wasting money on these overpriced no name tools. Just get the hyper tough cheaper then all these tools and gets the job done
Unfortunately I can’t seem to find the Hyper Tough
What are they. For most diyers these cheap ones are fine. You dont need to spend hundreds
