The NR90AEPR framing nailer drives plastic collated nails from 2 in. up to 3-1/2 in. in length. Weighing only 7.5-lbs. it is easy to use all day, while still providing the power of a bulkier, heavier nailer. It can be used for floor and framing, truss build-up, window build-up, subflooring, roof decking, wall sheathing and housing construction.

  • Accepts 2 in. up to 3-1/2 in. plastic collated framing nails
  • Lightweight at 7.5-lbs. and well-balanced for ease of maneuverability and less user fatigue
  • Selective actuation allows for quick transitions between sequential and contact nailing with the flip of a switch
  • Tool-less depth adjustment dial allows the user to countersink or flush drive nails into a variety of materials without having to adjust the pressure at the compressor
  • Two-piece anodized aluminum magazine makes repairs or replacement easy and with minimal expense
  • Two-step nail loading makes fastener replenishment quick and easy, reducing downtime
  • Rubber grip provides comfort and ensures a secure grip

Rated 4.7 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Reliable I purchased my NR90 framing nailer along with an 18GA a 15GA finish nailers and the 6gal Pancake compressor. I have nothing but praise for each component of this setup. I am a homeowner, not a contractor, but some of my projects can be a good test of the worth and value of a product. My Hatachi-Koki pneumatics are reliable and a joy to use. Would I recommend them to another? Yes! Would I purchase them again? Absolutely! January 8, 2013
Rated 5.0 out of 5.0 by Very dependable I used this gun to frame up the inside of my 45x60 pole barn.It worked flawlessly in 100 degree or 10 degree temps.Lots of power.A rafter hook and a case would be nice,but all in all a very good product. January 28, 2013
Rated 5.0 out of 5.0 by my favorite gun Extremely light, uses full head nails, tough. I would recommend it for any job. I just wish it had a joist hanger. January 9, 2013
Rated 2.0 out of 5.0 by HITACHI'S CORVAIR Like the guy on 3/15 said, lots of jamming and feeding problems. I have been using Hitachis only for the past 35 years and bought this one for the flush nailer, that part I like. Don't know why they changed the design, but missed the boat on this one. As long as you are nailing flat or down it seems to work OK. Nailing vertical I have found that I can only load one strip of nails at a time. I you are only using it part time or not professionally it works fine. But you can't beat the nr83. Someone is probably still using the ones that they stole from me over 20 years ago that had well over a million nails through them. April 21, 2014
Rated 5.0 out of 5.0 by So far a good little nailer Licensed contractor, been using a NR83 for over 10 years and have put up countless houses with the same gun. Its getting tired, so decided to get another gun as backup; was hesitant to change, but decided its a little lighter and smaller and Im not getting any younger. Have had it for about a month now, so far its been flawless, same Hitachi quality, the smaller size was nice on a recent job puttin in roof blocks between rafters. If this thing last as long as my old NR83 I will be very happy. Only bad thing I can say is it doesnt have a rafter hook, but you can buy them for about $15... March 18, 2014
