Amazon.com Review
This is without question one of the toughest, best-built roofing nailers we’ve ever had our hands on. We expected no less from Hitachi, but we were pretty much in awe at first use.

The side load is a great improvement over having to turn the tool over to fill your magazine, and loading literally takes a few seconds. Adjusting the drive depth is just as quick and easy, accomplished by turning the knurled knob. It’s got a smooth, clean design that leaves it perfectly balanced in your hand, and it’s so much lighter than it looks, at 5-1/2 pounds, thanks to Hitachi engineering. The rubber grip is comfortable and gives you a great, secure hold, and rubber pads give the nailer a little traction on steep surfaces.

Its bounce-fire mechanism will keep up with even the fastest roofer, but we think picking up the optional sequential-fire mechanism is a good idea for situations where absolute precision is key. It uses wire-collated nails, 7/8 to 1-3/4 inches, and the magazine holds 120 fasteners.

Most roofers just accept nail jams as an occupational pain, but this Hitachi is exceptional in its performance, shooting off coil after coil without a moment’s trouble. To top it off, this is one of the most rugged steel armatures we’ve met. Professional roofers will love this nailer, and if you’re a brave do-it-yourselfer, don’t make the mistake of buying a cheap nailer – the relatively slim savings is definitely not worth it. You cannot go wrong with this roofer. -- Kris Jensen-Van Heste

From the Manufacturer
The old stand-by tool just improved. Hitachi's new side load bucket is mounted on the same housing and feed system that makes the NV45AB one of the most durable tools in the market. This new roofing tool provides quick fastener changes without turinig the tool up side down. A new tool-less depth of drive allows accurate fastener driving. The NV45AB2 comes complete with a rubber grip handle and housing wear sheilds.

From the Manufacturer
The NV45AB2 has a new side load magazine which reduces loading effort adding convenience to the roofing contractor. The tool-less adjustable depth of drive allows for quick adjustments while on the roof to prevent the nails from damaging the shingles. A durable rubber grip handle now replaces the racket grip handle improving comfort and reducing end-user fatigue. While the housing of the NV45AB has always been equipped with metal body protectors, the NV45AB2 has incorporated rubber pads into the metal body protectors allowing the tool to grip the shingles to prevent the nailer from sliding off the roof. The NV45AB2 is still equipped with many of the outstanding features of its predecessor. These features include a feed piston with pneumatic feed and pneumatic return unlike many competitors that feature pneumatic feed and spring return. The pneumatic feed and return greatly reduce jams by allowing the tool to power through tar and other job site buildup that may inhibit the proper operation of the feed mechanism. Body armour on the housing and magazine prevent excessive wear to the nailer that is caused by shingle abrasion. Also, the carbide tipped push lever extends the life of the tools nose. The NV45AB2 continues to maintain a rapid firing speed of three nails per second and a weight of only 5.5 lbs., one of the industry’s lightest. A sequential trip mechanism kit is offered as an optional accessory for the NV45AB2.

Customer Reviews

Excelent quality
This is a well made roofing nailer, I own several other hitachi nailers (framing amd siding). I'm very pleased with all of them. Owned both Duo Fast and Stanley Bostich before, I'm glad I decided to switch to hitachi..

Hitachi NVAB2
This roofing Nailer jammed more than I think it should. You could figure on at least one jam per roll which is 120 nails! The point that is most likely to jam is at the last nail. Usually it falls out on its own but if it hangs up you can figure on a jam. I also had it shoot two or even 3 hails at a burst. It is not that I am heavy on the trigger. I don't know why it does that! Overall it think it is a good nailer. I expect some problems but they were minor when you consider the time I saved over nailing them by hand.

Does Hitachi Test before shipping
The Nailer I received would not advance to the next nail. The problem was solved by repositioning the piston cover. There was no rust or contamination on the parts. I assume that this was a one of kind problem. Everything else about the nailer appears to be of the quality expressed in the reviews.
