Hi everyone after a long time waiting for it today this Gisam 1/2" impact wrench has been delivered to my door
I've tested it and I soon realized both good and bad things about it.
Very poor packaged resulted in few scratches and ruined over moldings, I've had to clean it up because was covered with what look like paint but after that doesn't look bad.
Anyways I've borrowed a 4Ah battery from my Yofidra 3/4" TW001GM clone (actually XGT clone but made to work with LXT batteries) Wich you can see in the picture up above.
It didn't fit in first place due to the classic Chinese quality molds, I've had to trim few little burrs here and there to make it fit like a glove pretty easy fix.
Now good thing at first impression, I've used a 4Ah battery and adapter, put a socket and torqued a bolt with it and rounded the square on the socket (impact socket provided with the DTW300 clone).
I've had to disassemble the impact to solve the battery problem.
And that's how it looks inside
General Chinese brushless impact internals?
Not exactly we have generic PCB as most of them but wires seems little thicker.
The switch doesn't look that bad overall and seems better quality than the DTW300 clone
The switch actually do stepless variable speed not like the unmentioned clone which only does 3 steps, or at least you are not going to feel the steps.
PCB too does 3 individual speeds forward (DTW 300 clone does low and high)
Full power reverse with autostop function on or off.
PCB and switch together make this impact pretty good to use
The speeds and auto stop mode can be selected on this more Makita looking panel
Now the motor
The stator itself it's not that bad, with good windings thickness but they completely ruined their work by missing the cutout to run the wires through.
The rotor on the other hand surprised me
Despite the cheapness of the tool (50£~60€) it has first of all a nice and robust cooling fan.
And the rotor spins on two 608-2RS shielded bearings which is nice to see
the gear nose is milled directly on the rotor shaft too
