Bosch is now shipping two EXPERT 18V framing nailers that skip the compressor entirely. Arriving at authorized dealers are the EXNH18V-90MDN (30-degree) and EXNH18V-90MRN (21-degree), both using an internal air-spring system pressurized to 117 PSI through a Schrader valve. Both are available now for $429 bare tool.

How the Air-Spring System Works
An air spring inside the tool stores energy when the driver blade resets, then releases it on the next trigger pull. This is different from a flywheel nailer: the spring does the driving, not a spinning motor. Energy is rebuilt between shots, so the trigger feel is consistent from the first nail to the last.
A jobsite-accessible Schrader valve lets you top off the internal tank with any portable compressor when pressure drops. There are no gas cartridges or fuel cells to buy and stock. At 117 PSI, the spring drives 3-1/2 in. nails through framing lumber without partial drives or jams on back-to-back shots.
Milwaukee’s M18 FUEL framing nailers use a flywheel-based electromagnetic system, which is also consumable-free but mechanically distinct. Paslode’s cordless models paired CO2 with a gas fuel cell. Bosch’s approach eliminates both.
Which Angle to Buy
The 30-degree EXNH18V-90MDN handles clipped head nails, standard in residential framing on the East Coast and throughout the South. Most production framing contractors in those regions already stock 30-degree strips, so this is the default pick for someone without an existing nail supply.
The 21-degree EXNH18V-90MRN suits West Coast framing and any job where local code requires full-round-head fasteners. Check your jurisdiction before buying: some seismic and wind-zone codes specifically prohibit clipped head nails for structural sheathing, which rules out the 30-degree model regardless of preference.
Who It’s For
These are contractor-tier tools aimed at framers and deck builders who want cordless convenience without fuel-cell costs. The $429 bare tool price matches Milwaukee’s M18 FUEL framing nailer entry point. Bosch 18V users already have compatible batteries; anyone starting fresh should look at the kit version (EXNH18V-90MDB14), which includes a 4Ah EXPERT High Power battery and a fast charger.
Where to Buy
Both models are available now through authorized Bosch dealers including Acme Tools and ToolUp. Bosch tools typically arrive on Amazon within a few weeks of dealer launch, so check there as inventory expands. The kit version (EXNH18V-90MDB14) bundles the 30-degree nailer with a battery and charger for those starting fresh on the platform.
