I like powered ratchets, battery or air, big but preferably small. They just make your life easier, the less manual turning of the wrench or ratchet you do the better your body will endure. At least that’s my theory. So when I found out about an impacting air ratchet that’s about the same size as a standard air ratchet from the good folks over at Garage Journal I was like “wow I need that” and its
cheap inexpensive at only $72 dollars.
The harbor freight earthquake 3/8″ impact ratchet. Is rated at 70 Ft-lbs max power which isn’t the most powerful impacting ratchet in that form factor or size but it is the most powerful impacting ratchet you can get in that price range.
How well does it work? I have been using it all day today at work and so far it works really well. First job was a set of sway bar links on a ford transit connect. Right away I noticed the impacting action and it took those links right off. Second job was a noisy A/C compressor on a Honda civic. That Honda was Not really a challenge for the Harbor freight earthquake air ratchet as most of the bolts are just 10 and 12mm. But it handled it without fuss.
What’s as impressive as its power is its speed. It’s not as fast as my IR hammerhead 2015MAX “Right angle impact wrench”. But it’s at least twice as fast as my snap on far72c air ratchet and a lot faster than my Milwaukee m12 electric ratchet. But unlike my IR hammerhead impact wrench it fits into a lot more spaces and i can manually break fasteners loose if it doesn’t have the balls to do so on its own. It’s rated at 400 rpm and that’s a good amount of speed to get the job done quickly. Most standard air ratchets are rated around 160 to 200 rpm give or take a little.
Durability? This I can’t comment on just yet because i have only used it for a day so far. My initial impressions are that it should be plenty durable as i don’t feel like any of the external components are cheap or flimsy. I also think that this impacting ratchet may be made by Sunex as it looks Almost Identical to the sunex impacting air ratchet. You can see the sunex version in the picture below. The specs are almost identical and they look very similar
