Metabo HPT (formerly Hitachi) is producing some impressive tools these days. You may have read our reviews on theirย rotary hammer,ย impact driver,ย and several others. Iโve had the good fortune to a review few of them myself. Concurrent to the test of the Metabo HPT 2โ1/2-Inch Coil Siding Nailer,ย I also tested its big brother, theย Metabo HPT 3-1/2-Inch Coil Framing Nailer. Itโs no surprise there are some design similarities, but will the big gun be as much of a hit as the small one?
Iโm ready to find out.
First Impressions
Theย Metabo HPT 3-1/2-Inch Coil Framing Nailer is a handsome gun. Itโs surprisingly light at 7.7 pounds. Of course, that size is necessary to generate the force at 70-120 PSI to drive the 1-3/4- to 3-1/2-inch, 0.099- to 0.131-inch diameter framing nails.
The side-loading magazine tilts out slightly for easy loading just like the Metabo HPT Siding Nailer and accommodates 200-300 wire-collated nails. Unlike the siding nailer, however, the magazine isnโt transparent so itโs not possible to see how many nails are left on the coil.
It has the same selective actuation switch I like so much on theย NV65AH2 that allows the user to change between sequential (single) and continuous (bump fire) actuation. Another echo of the siding nailer is the depth of drive dial. In the old days, Iโd just adjust the pressure on my compressor if nails were sinking too deep or standing too proud, but thatโs not very convenient if Iโm up on a roof or ladder! So this is a helpful feature thatโs become an industry standard.
Finally, the overmold grip seems comfortable at first blush. It includes some textured bumps for added control. Of course, the real test is having a magazine full of 300 heavy framing nails!
Whatโs In A Frame
As I mentioned, a framing nailer must be larger than its siding or roofing brethren to generate the force it takes to drive the longer, thicker nails used in building the wooden bones of a building. Thatโs why framing nailers typically go with a stick magazine design. The plastic collated strip is lighter than a coil full of nails. The weight trade-off for the typical stick framing nailer is that work must stop more frequently for reloading.
But because theย Metabo HPT 3-1/2-Inch Coil Framing Nailer is so light, it can incorporate the coil design to give the user the best of both worlds. It has the power to drive large framing nails with the nail capacity of a siding or roofing nailer. Still, a fully loaded magazine certainly wonโt be a featherweight by any means, so have an extra protein shake in the morning and enjoy the uninterrupted workflow.
Loading
Loading and adjusting the magazine for nail length is a breeze. The side-loading magazine has a tilting feature that makes putting a new coil in very convenient. Itโs much easier than the clumsy design of older nailers. The caveat here is the same with the siding nailer: the magazine just feels flimsy compared to the rigid stick magazines. I havenโt had one break, but it just doesnโt inspire confidence. Time will tell if it holds up.
Early Performance
I usually use the bump fire actuation, which has been flawless over these first few weeks. I didnโt have any jams or misfires. As I mentioned, the depth of drive dial on the gun is a time and effort-saving feature โ no more adapting the regulator dials for depth. Perhaps best of all, the gun is well-balanced which makes even the full magazine seem lighter. The overmolded handle is comfortable to hold and the trigger pull is easy.
Moving from a stick to coil framing nailer means youโll have to give up your dry fire lockout. Comparable models from Bostitch, DeWalt, and others donโt include them, either, so itโs not a standard feature. Just realize itโs not there.

Being Nosey
I especially like the nose that bites into the wood, making toenailing easy. The nose design is open underneath, which Metabo HPT tells us will make clearing jams easier. Iโll let you know once I finally have my first one.ย As it is, it at least appears to make it easier to access the jam.
Room for Improvement
For improvements, Iโd like to see a swivel air inlet to accommodate hose movement. Iโm grateful that Metabo HPT provides an inlet connector since some manufacturers donโt, but I do love my swivel connectors. On the more significant side, Iโd add a rafter/belt hook. It would make working at height much easier while climbing.
Thereโs also the issue of knowing how many nails I have left. Adding a window to the magazine like we see in the siding nailer would handle that well. Finally, Iโd prefer an adjustable exhaust port for those awkward positions when itโs directed right at me.
The Bottom Line
Coming in at 7.7 pounds and boasting up to 300 nails takes framing to another level. Of course, a fully loaded magazine is going to be heavier than the traditional stick designs, but you wonโt stop to reload as often.
From a performance standpoint, the Metabo HPT NV90AG(S) has performed flawlessly in my first few weeks of testing. Ergonomically, the nailer is balanced well around the idea of having a heavy magazine load and offers a secure grip.
A few features are missing that Iโd like to see on the next generation including a rafter hook, adjustable exhaust, and magazine window. And yes, if youโre going to provide an inlet connector, please include a swivel model. While these stand out to me as areas for improvement, neither individually nor as a group are they a deal breaker in my opinion. The performance, ergonomics, and capacity outweighย them.
Theย Metabo HPT 3-1/2-Inch Coil Framing Nailerย comes in at $269 with a 5-year warranty. Thatโs not the cheapest framing nailer youโll buy, but itโs not bad for the coil framing class. Given Hitachiโs reputation in the nailer category and the performance Iโve experienced, I can recommend this one to other Pros.
