si è rotto il bullone al primo utilizzo, forse per errore mio, stava pressando storto. lo sto rifacendo fare in acciaio dal tornitore

convient à notre utilisation

The knockout punch works well but has starting leaking after on 20 holes. Please guide me on how to get a replacement sent to me. Thank You

Works well, just wished they offered metric sizes. A 22mm size hole is too big for todays 20mm brass bush same for 27mm and 25mm brass bushes.

Cutting 5 holes stop working. Brand New.

Get what you pay for. 1st job I used it on on my 3rd knockout the threads stripped on the main threaded bolt. Good price but didn’t last long

The first time I went to use this tool it didn't work. I followed the instruction and still doesn't work. Bleed the system and added oil still nothing. Contacted Vevor and they sent a video showing you have to smash the pump on the ground to get the tool to work. Not worth dealing with or buying

Opened it up out of box and it leaked the first use had to salvage parts from another broken one to get the new one to work. First hole it leaks hydraulic fluid

I bought it mainly because of the price. It worked a couple of times but after a while it started blocking while punching holes. The feedback received from product support suggested hitting the unit head against a solid surface for a couple of times. It worked but the problem appeared again after a while. Despite the technical specs the set is not suitable for punching holes in stainless steel metal sheets (tried 1.5-2mm thickness). I definitely cannot recommend it for professional use.

It can be used as a toy. It is just completely useless, the piston stroke is too short, the screws are too short, so nothing can be done to the car, no suspension bushing can be pressed in or out
