Well-constructed. Rugged. A bit large and heavy. |
I had a cheapie electric impact wrench from Harbor Freight. It worked well, but the screws that hold the gear case to the plastic housing tore out of the threaded plastic holes. I found that almost all of the electric impact wrenches had that same design. Then I discovered the Makita TW0350 had a better design. The screws go in the opposite way - through the plastic housing and into the metal gear case. That will prevent the kind of failure I had experienced.
The Makita TW0350 seems well constructed and tested out fine. As of this review I have not used it extensively, but I am confident from the brand's reputation that it will be durable. There is a rubber coating over the front to protect it. The handle is well placed for balance.
The only downside is that the tool is fairly large and heavy, much more so than an equivalent air tool and many other electric impact wrenches. If you used it all day, the weight may become an issue. I only use it a few times a year for home automotive use (tire rotations, maintenance, etc.) so that was not an issue for me. Also, if you use an impact wrench in cramped areas, the large size of the TW0350 may be a problem.
I should mention that for any impact wrench, using it for removal of nuts or bolts is fine, but when tightening a fastener, you can easily over-torque it. The Makita manual gives you a chart of how long to allow the wrench to hammer once the fastener is tight, but that is no guarantee of reaching the proper torque. An impact wrench should be used with a torque stick when tightening fasteners. However, my experience with electric impact wrenches is that their hammer rotation is too short to twist the torque stick fully, so the resultant torque is less than the stick's rating. That is not a problem for me because I always use a hand torque wrench to make the final torque adjustment. Just remember that if you torque a fastener beyond its rating, using a hand torque wrench to check it doesn't work (though I see mechanics doing this all the time) because the fastener is already too tight. To use a torque wrench, the fastener has to be tightened below the final torque setting. You should see the fastener turn at least a 1/4 turn as you are making the final torque adjustment by hand. If it doesn't turn, loosen it a bit, then re-tighten it with the hand torque wrench. |

Excellent Purchase |
|
I bought this tool for Home Improvement assembly work, and after using it for 2 weeks there's nothing I don't like about it. Has more than enough torque to do everything I need very quickly and is pretty comfortable to use even when using for long periods working at extended reaches One of the better tool purchases I've made. |
