Rated 3.8 out of 5 by 26 reviewers.
Rated 3.0 out of 5.0 by Not what I expected... I am a believer and owner of numerous Ridgid tools over the years as a contractor. I do love the versatility of the Jobmax tool suite; however the "Auto Hammer Head" is useless with the 18V power base attached. It would not drive a 16d nail in a spruce 2x4. If you plan to use it, attach the 120V or the air powered base. November 24, 2014
Rated 5.0 out of 5.0 by Durable, Easy to use, Sturdy, Good Size & Weight, Long-Lasting great warranty Works great as an accessory to my JobMax. Easy o attach/detach, plenty of torque.It does what it's designed to do. November 25, 2014
Rated 4.0 out of 5.0 by works great in tight spaces Works great in tight spaces, I built a loft in my garage and kept my knuckles from being busted up. November 24, 2014
Rated 4.0 out of 5.0 by Used with the 18v power base. Works good. I've seen videos of this tool with the 12v base and was not impressed at all. In fact I thought I would never own one but I found one in the clearance section for dirt cheap so picked it up. Using this tool with my 18v JobMax works pretty good. I can easily drive a 3inch spiral nail no problem. I also use two hands and support the back of the tool above the nail as it's driving in (similar to the Milwaukee designed auto-hammer) I've noticed some reviewers are trying to use this tool in place of a hammer altogether but they seem to overlook the main purpose of this tool which is for driving nails in hard to reach places where you can't swing a hammer. Between joist, under counters etc. November 26, 2012
Rated 2.0 out of 5.0 by Not as strong as expected This tool does not perform as strong as the other JobMax tools. April 21, 2015
Rated 5.0 out of 5.0 by Tool works as expected! I did not like the fact that there was a problem with the LSA program for this tool, which is the only reason I buy them. Otherwise it would be Milwaukee all the way. February 28, 2015
Rated 3.0 out of 5.0 by Good value but lacks a bit of driving power I purchased this for use on my Ryobi ONE+ 18v tool. It is not advertised, but all the Jobmax heads are interchangeable with the Ryobi ONE+. This hammer head works okay, but certainly does not have the power of my air powered palm nailer which uses the exact same concept with a different configuration. For the cost it is well worth it for those few locations where swinging a hammer is not an option and you won't feel like breaking out a compressor and air line or just don't have the 110v plug available. January 28, 2015
Rated 5.0 out of 5.0 by Amazing Performance This little gem gets in where my hammer won't. Even with gloves on you can get into tight spots. I bought it in hopes of speeding up the process of driving thousands of 1 1/4" nails for joist hangers and hurricane straps and it really saved the day...and my fingers! February 10, 2015
