Wasted a whole day back and forth to Harbor freight. I should have know better. Avoid this air shear or any from Central Pneumatic.
Inline Air Shears I took it apart and it would have worked well if it had 3 planetary gears instead of only one.
I decided to order a different one from Amazon as they will pay return shipping if it is bad. Many of these style tools have several bad reviews along with the good reviews, so your experience may vary. My guess is many of the heads or nibbler parts could be from the same factory. Might want to keep the thread alive for other tools. Maybe tomorrow I will tell you about the junk Central Machine pan brake I just got.
