Hitachi NR90AC3 Round Head 2-3/8-Inch to 3-1/2-Inch Framing Nailer

From the Manufacturer

Durable, powerful, and versatile, this full round head framing nailer from Hitachi is packed full of features that stand up to the rigors of professional framing projects. Hitachi simplified the magazine by designing it as one solid piece of extruded aluminum, so there are fewer parts to disassemble, fewer problems, and optimal durability. The body is constructed of tough, die-cast aluminum capable of withstanding the worst jobsite abuse. A filtered air inlet protects the tool from dust and corrosion for years of great performance. Operating between 70-100 PSI, this nailer drives up to three round head nails per second. An aggressive nail push lever grips the work surface for precision and accuracy. An idling protector prevents dry firing an empty gun, and a depth of drive adjustment dial enables one-touch depth adjustment from counter-sinking to flush driving. A 360-degree directional exhaust shoots in any direction to keep it out of the operator's face. Comfortably sized, the NR90AC2 is designed for daily use by the serious professional. And, weighing in at only 8.9 lbs, this nailer is compact and lightweight for easy handling and reduced operator fatigue. A rear-loading magazine makes it easy to load nails, and a soft grip handle feels good in hand. All in all, this is one fantastically adaptable and user-friendly tool.

5.0 out of 5 stars Some comments on the negatives, March 20, 2006

This review is from: Hitachi NR90AC3 Round Head 2-3/8-Inch to 3-1/2-Inch Framing Nailer (Tools & Home Improvement)

I own a NR90AC2,same gun but does not have a lever select on the trigger:
On the 8d nail issue,in that size, I shoot ORCO brand,made in USA, in the gun, 2 3/8" ring shank Egalv. and never had a jam. Cheap off brand nails or the wrong angle=jams. 6d(2") nails are not for this gun. I always shoot ringshank into sheet goods b/c of the better grip. 6d's are not code here in CA anyway.
The single fire AC2 issue, you need to change out the trigger, the included one is a NOT a single fire(sequential) and will easily double fire, it is a contact fire(bump) type. Change out the trigger and you can not double fire as was said. AC3 has a lever to change it, AC2 you have to change out the whole trigger assembly.
This is an excellent gun ,drives into anything wood,but you have to use good quality nails and be aware of the trigger b/c it has a lot of power. I do not usually use bump fire, can be a safety hazard,waste of nails,inconsistent depths, but you even can bump fire one nail in the sequence mode, great feature on the AC3.

11/09 update; Now using an AC3 with a skilsaw rafter hook added, I updated only because I like the easy flip trigger lever;still no issues with 8D's except I had 1 jam due to the plastic collation strip was doubled over from a partial strip stack,remove rear magazine bolt, remove jam, replace. Forgot to mention also using Grip Rite and Senco ring shank galv 3" are excellent for grip and can be used in PT lumber as well. Basically an all metal design, high quality ,made in Japan is just as good as it gets if you want a powerful well made framer that shoots CA code RH 16D 3.5" x 0.162. Still the best out there IF you do not use cheap off brand nails. And, it is not the alien ugly neon green on the now discontinued models. They have gone back to the classic pale green most prefer and idenify with hitachi air tools

9/2010
Totally disagree on review panning gun for sheathing. . Again I use this all the time for 8D, sheathing, etc. , and have only a very rare jam if you are working correctly. The reviewer who said this gun is not for sheathing is dead wrong. They either are not using quality nail strips and or are damaging the ends of the collation strips so the nails do not line up properly in the Mag. Senco;s 8D's if not damaged will not jam, period. Some are better off using a wire collated coil nailer which can hold way more nails and you can shoot wild machine gun style as a lot of track home laborers/builders do thinking they are laying down asphalt roofing and can put a nail anywhere because it only has to enter the sheathing. . Many of those nails shot like that in structural sheathing are shot into thin air missing the supporting lumber. Fails code, wastes money on materials and labor to fix if caught in inspection, or makes for a weak house.... if you are in a hurry , do not want to buy quaity nails, be precise in use and loading the mag. [as I often see people do] and being as fast as you can be to just get the job over-with as your main concern, this is not the gun for you. It will cause you to have the gun jam,

5.0 out of 5 stars Hitachi NR90AC3 Great Nailer, August 7, 2004

Great Nailer, a little heavy but nicely balanced. I have been using this nailer about three months @ 10 hrs a day without any problem whatsoever. For heavy use, I recommend putting an automatic oiler in your air-line as that makes the tool perform much better than having to add a few occassional drops.

The manual states that the minimum nail size is 2-3/8 (ca 8d); though the factory literature and on-line advertising says that the minimum is 2". I am using 8d nails, so I am not sure about the lower limit. However, for those wanting to use nails smaller than 8d, I would recommend talking to an experieced retailer about the product capabilities. It is not an inexpensive tool, so make sure it does what you want.

3.0 out of 5 stars Doesn't shoot all nails, February 25, 2006

This review is from: Hitachi NR90AC3 Round Head 2-3/8-Inch to 3-1/2-Inch Framing Nailer (Tools & Home Improvement)

We Purchased the NR90HitachiAC3 because we liked the Hitachi83 that we had for years, but didn't have an adjustment for the nail depth. They advertise that it shoots nails from 8's to 16's. The bigger nails, it shoots fine with not much kick back. Doesn't jam on them. The 8's are a nightmare. That is the main reason that we bought the gun for the 8's as we wanted to be able to adjust the depth while doing the sheathing for all the required engineering. The nails either jam or the slide slips by the nails. Not just a few times, but every time.
If you are buying this gun for shooting 10's or 16's then it is a fine gun. If you want it for nailing the shear walls with 8d's... forget it, it is a waste of time and money.
