Hitachi NR90GR Round Head 2-inch to 3-1/2-inch Cordless Gas Framing Nailer
I purchased this nail gun for a roofing job that required a total reframe of the sagged structure. I was excited to avoid the hoses all over the place and the sound of the compressor over my stereo.
The description says it shoots 3 1/2″ nails. It does shoot them, but only 20% actually go in all the way. The depth adjustment was as deep as possible and I tried everything to get the nail to fully lodge into the new lumber. I ended up having to go back over the entire structure with my framing hammer and spend 30-45 minutes setting all the nails.
When the framing was complete, I thought I’d be home free with the sheeting nails at 2 3/8″. The gun misfired and misfired and misfired some more despite changing nail types (I bought nails at Home Depot AND the ones on the Amazon detail page with no difference). After the gun stopped firing completely, I quit and hand nailed the rest of the sheething.
The reality with this gun is that a good framer can hand nail faster than this gun can shoot nails. Between not sinking the all the way and misfiring, the tool is more trouble than it’s worth. I returned it and purchased a basic Dewalt pnuematic framer and have had much better success.
I wouldn’t recommend this gun to anyone unless you enjoy frustration, slow results, and the constant desire to throw this tool across the parking lot.
The Hitachi NR90GR that I purchased looked great but did not work. It would not feed nails. I returned it and purchased another higher priced, higher quality nailer.
I’ve had this nailer for over a year and put about 500 nails through it. While framing up a window recently I smelled something burning, I stopped and looked at the gun and noticed the housing had cracked around the entire gun and was falling apart. Wish I could post a pic to show what happened, the gun is now useless and the warranty is expired. Big waste of money!!!!
This tool works very well with a few limitations. You need to keep a hammer handy to finish driving the odd nail. It works well, has never mis-fired and works without the noise of the compressor.
I bought it to work on our Summer home which is off-grid. This nailer lets me work without running the generator to supply power to the compressor. That is a substantial savings in both gasoline and noise.
I recommend this nailer for small jobs where you don’t want to drag out the compressor. Framing crews are not going to use this tool but it is great for pick up work.
This Hitachi gas framing nailer is worthless.
It says it will drive a 3.5″ nail all the way in but even threw soft wood it leaves the nail stick out half an inch. so I bought 3″ nails and it sinks them all the way.
The gun doesn’t shoot any nail about 1 out of five times. I can hear the gas chamber’s fan turn on but no nail comes out. I tried a new battery and new gas cartridges all to no avail.
I am building a barn and will be walking around in rafters. I can’t have a tool that sometimes works.
DO NOT BUY THIS piece of junk. I had a paslode before and it worked fine.
