Milwaukee M12 1/2 Stubby vs Parkside Performance Prototype 1/2 Impact Wrench

Hello YouTube and welcome! Today I will present 
you this brand new Parkside Performance impact   wrench. The model is a prototype so not much 
information is available on it – no model number,   no specifications, no nothing. However really 
interesting is the close resemblance to this   Milwaukee M12 stubby impact wrench. Parkside 
model is about half centimeter longer. The   diameter and the height of the machines is 
about the same. Both machines are equipped   with the torque selector with four settings. 
Being a prototype the body of the Parkside   is not made in a mold using the standard Parkside 
plastic and rubberized elements, as far as I can   tell it's made by using CNC milling machine and 
a white plastic which later is painted black. The   body was heavily scratched due to the laboratory 
testings so I used a permanent marker to hide some   of the scratches. Most likely this won't be the 
final design of the machine and there will be   some changes before it hits the market. Probably in 
the design of the ugly torque selector and maybe   in the battery level indicator too. The weight 
of the Milwaukee is 955 grams while Parkside weights a little bit more.

The 4Ah 
RedLithium battery is 407 grams and the   Parkside battery is 408. Parkside 
is way louder than the Milwaukee. The no load rotational speed at the 
highest level on the Milwaukee is.. Some interesting differences between those   two – on the Milwaukee when set on 
level 4 and the rotation is right the machine automatically stops when a 
certain amount of resistance is detected. When the direction is left the 
machine is rotating at full torque. On the Parkside when the direction is 
left and we have four illuminated LEDs   on the torque selector the machine rotates 
at full power when it senses a resistance. But if there is no resistance 
it automatically stops. When the direction is right we 
have four different torque levels. This is what we have inside. Of course the 
Milwaukee is way better manufactured, but   let me remind you that the Parkside is 
still a prototype. Those are the two rotors. And the two machines from a little bit closer. We have a brushless motor with Hall sensor on   the Milwaukee while on Parkside it's 
a brushless motor without Hall sensor.

And I think that the hammering mechanism 
on the Parkside is a little bit longer. We have a super large radiator on 
the control board of the Milwaukee. We do have a radiator on the Parkside but it's really tiny one.   This is the Milwaukee hammering mechanism 
and this is Parkside. I think that   the hammer on the Parkside has more mass. On the 
anvil of Milwaukee we have a rubber O-ring for   retaining the grease inside. No such feature is 
available on Parkside. I really like how the back   plate of the hammering mechanism is manufactured 
from aluminum on Parkside. On Milwaukee it's   simple plastic.

Let's measure the instantaneous or 
dynamic torque on highest setting on both machines. Direction of rotation – right. 66 newton meters Direction of rotation – left about the same 65 Direction of rotation – right 63 left Only 60. Let's begin with one really simple test –  tightening this bolt with Milwaukee then 
untightening with Parkside and vice versa. Continuing with the bigger bolt. 274 newton meters 262 a little bit less but let's see 357 359 456 459 527 let's do it one more time 559 sorry 56. and lastly let's try around 600 newton meters 629 634 That's nice it has and overload protection. Yeah it overheated. While it's still 
warm let's try it one more time. 649. it's still warm Same bolt, I think it was 649Nm. Lets try with the Milwaukee. As a conclusion I will 
repeat myself once more but definitely the   Milwaukee is the better tool.

It has a lower no 
load rotational speed than the Parkside, but   judging by the sound under load it has a higher 
impact rate. Regarding the Parkside I can say   only positives. It's really close competitor 
to the Milwaukee and most likely it will be   one third of its price. Not to mention that it 
has an overtemperature protection. Probably the   new Parkside model will hit the stores by the end 
of the year, maybe even sooner, I don't know.

I   think that's enough for this video if you'd like 
it you know what to do guys. Bye and see you soon..
