Hot Rod magazine gave generous props to the Central Pneumatic Earthquake 1/2" Impact Wrench (#68424) in the Parts & Stuff section of their January 2013 issue:
"This is the Cadillac of ½-inch impact wrenches. From Harbor Freight, known for great tools and cheap prices, the Central Pneumatic Earthquake ½-inch Impact Wrench is rated at 700 lb-ft and has three forward speeds plus reverse. It has twin hammers inside that help to make more torque easier. It has less vibration than the competition and, according to Harbor Freight, is the most powerful wrench in its class. One other cool feature is that the exhaust port is pointed away from the user, so no more blowing air in your face when using the tool."
While I do love Hot Rod for being a renowned mag, full of informative articles, how-to's, showcases, etc., they'll have to go to the back of the line on this one. Harbor Freight's Earthquake 1/2" impact wrench is already a well-documented legend for, not only its power, durability and performance, but also the great price-- just $94.99 (around $76 with a 20% off coupon)!
"Do we really need any excuse to go buy new tools for the garage? Of course we don't, but the new Earthquake air tool from Harbor Freight gives you 700 reasons to pick one up when you need to get those stubborn, rusty fasteners off your Mustang!
"This professional class wrench (Item# 68424) delivers more power with better weight distribution, lighter materials and a more compact housing. Premium grade components with close tolerances give this tool a longer lifespan than conventional air wrenches."
"Harbor Freight returns with another price-conscious tool that should be in every garage: the Central Pneumatic Earthquake half-inch impact wrench. You may not need this tool for everyday wrenching on the bike, but when upgrading or replacing worn out sprockets requires the removal of a countershaft sprocket nut that will not loosen by hand, you’ll appreciate this tool’s power. The Earthquake Impact Wrench is an affordable way to get the job done with a torque range of 50-500 LBS.-FT., a working pressure of 90 PSI and three forward speeds. Make dropping a tooth or two with an aftermarket front sprocket easier with this tool."
And it's not just the magazines. Tool hounds at home also like the Earthquake impact wrench. For example, on this thread in GarageJournal.com's forum, several members admitted their fondness for the air tool:
"I've had one for a bit over a year and have used it quite a bit. I have yet to come across something that I was unable to get off with it..." strizzy
"I bought one a couple of years ago and couldn't be happier with it. Incredible power and comfortable grip.... It's been used and abused and just keeps on going. I'm sure keeping it lubed properly helps too. With an adapter and a Budd socket it even removed nuts from a truck that someone had swaged on with a cold chisel to make sure they NEVER came off. This thing had enough power to take them off right through the bunged up threads. I like it so much I'm thinking of buying their 3/8" Earthquake..." Curmudgeon
"I got the 1/2" one too. I use it every once in a while to remove some rusty hardware on my 20 year old sports car (read: bolts that have not been touched in a long time) and the Earthquake does it without any trouble. Its a great purchase even if it was double the price. But since its not...stop typing and go buy one!" sunshineFC3s
