The Hitachi Roofing Coil Nailer is made for roofing and construction projects. Its bounce fire mechanism keeps up with even the fastest roofer and the rubber pads provide extra friction. This nailer has a side load magazine for quick reloading and its (tool-less) depth adjustment allows you to change your driving depth. Simply adjust the depth and work with a variety of materials. It operates at 70 - 120 psi and comes with a rubber safety valve to resist dirt and tar. The pneumatic power feed and return make this tool extra tough and its carbide tipped push lever reduces wear. This tool delivers quick driving and uses 7/8 in. to 1-3/4 in. fasteners. The magazine holds 120-fasteners and is perfect for big roofing projects.

Rated 4.9 out of 5 by 29 reviewers.
Rated 5.0 out of 5.0 by Strong, Reliable, and Consistent Performance Recently we picked up the Hitachi NV45AB2 for a roofing job that was scheduled locally on a standard single level ranch-style house. Rather than go the easy route & re-roof overtop of the existing shingles, everything was removed --- with new paper & shingles being laid down. For this we used the Hitachi in conjunction with a couple of other brands (multiple people nailing at the same time), and over the course of 3 afternoons the roof was complete. The Hitachi by far outperformed the others....not only with ease-of-use, but also reliability. By itself, the Hitachi used a full box of coiled nails, and did not experience one jamb the entire time. The power is excellent & this was coming from the 100' Hitachi 1/4" green hose, and using the Hitachi EC89 Compressor. The other guys had continual issues....not only with their nail guns, but also their oversized/bulky hoses, and LOUD/unimpressive pancake compressors. By far the NV45AB2 outshined everyone else, and if we had used 3 of them ---- vs 3 different brands, the whole job would have run a lot more smoothly. It is reliable, powerful, and is extremely easy to use. December 7, 2015
Rated 5.0 out of 5.0 by This nailer is simply Fantastic!!!! My Hitachi roofing nailer, is lighter than any other brands I've used . Love the speed I've gained from the automatic trigger, and the flush nose tip. Thank you November 30, 2015
Rated 5.0 out of 5.0 by love it very much. beat the competition highly recommend for a successful day on the roof get this. for a light weight gun the only gun that takes a bad day seem good April 12, 2014
Rated 5.0 out of 5.0 by Simply the best! This machine by far surpasses all others. I've used Bostitch, Senco, Grip Rite and Harbor Freight nailers, but none come even close to this one. As for me, I won't ever settle for anything less then HITACHI... May 12, 2015
Rated 5.0 out of 5.0 by Never a miss fire. Never The reason I went with this gun over all the others is because i used them all and this one never jammed, Miss fired, or malfunction in any way. Another thing I like is this gun spits out the last nail on the coil. Some think thats a waste of a nail or theres a flaw with the design, and there might be for all I know. But for me i love it because i don't have to keep an eye on the coil to figure out when i used the last nail. This keeps me from denting the shingle rather than landing a nail every time. The cost is about the same as all the other makers so it was easy for me to make this choice. August 21, 2013

Rated 5.0 out of 5.0 by This nailer lives up to your claims! The light weight of the nailer was most appreciated, and I didn't have a single jam while installin 11 squares of shingles. October 1, 2014
