The Metabo HPT NR1890DRBQRY 18V Cordless Pneumatic 21-Degree Framing Nailer (model NR1890DRBQRY) is a battery-powered framing nailer that drives 2-in. to 3-1/2-in. full round head framing nails from 21-degree plastic strips. This is a cordless framing nailer designed for wall framing, floor systems, and roof framing where crews want air-nailer speed without a compressor, hose, or fuel cell. It ships as a kit with an 18V/36V MultiVolt T-PWR Tabless battery and a quick charger.

Instead of a motor-driven flywheel, the NR1890DRBQRY uses Metabo HPT's sealed air spring drive system. A brushless motor resets a piston against a charge of compressed air that lives inside the tool, so each shot has the snap of a pneumatic framer. Metabo HPT rates it at up to 6 nails per second in bump mode and 120 joules of driving energy, which is the kind of output that keeps up with a framing crew rather than slowing it down.

Runtime is where the 10.0Ah battery pays off. Metabo HPT rates the kit at up to 1,170 nails per charge, and the included UC18YSL3Q1Y quick charger brings that battery back in about 75 minutes. A dry-fire lockout stops the tool from firing on an empty magazine, which protects the driver and bumper and tells you it is time to reload instead of leaving you with a missed nail.

The tool weighs 7.9 lb without the battery and is built to feel like a pneumatic framer in the hand. Depth of drive is set with a tool-less adjuster, a switch on the control panel toggles between bump and sequential firing, and an LED lights up the nose for dim corners and attic work. A rafter hook and belt hook let you hang it from a joist or your belt between runs.

Maintenance is designed to happen on the jobsite. Metabo HPT sells a Wearable Parts Kit (384005M) with a replacement driver blade and bumper, a Maintenance Jig Kit (384003M) with the tools to swap them, and an Air Refill Valve (384002M) for topping up the air spring. Metabo HPT says routine service can be done in minutes rather than shipping the nailer out for repair.

The magazine is swappable with other Metabo HPT cordless pneumatic strip nailers. Optional 21-degree short and long magazines, 30-degree magazines, a metal connector magazine, and a duplex magazine are listed by Metabo HPT, so one tool body can be set up for different fasteners.

This kit is a strong fit for framing contractors, remodelers, deck and addition builders, and serious DIYers who already run 21-degree plastic-collated framing nails and are tired of hoses, compressor noise, and gas cartridges.

A Real Framing Nailer With the Hose Cut Off

The Metabo HPT NR1890DRBQRY gives you pneumatic-style framing speed on a battery, with enough runtime to frame, not just tack.

• Who it's for: Framing crews and remodelers running 21-degree plastic-collated nails who want to stop setting up compressors on every job.
• Why it stands out: 6 nails per second, 1,170 nails per charge, and an air spring drive you can service on site.
• Worth knowing: At 7.9 lb plus a 2.2 lb battery it is not a featherweight, and nails are not included.

• Does this nailer need an air compressor, hose, or fuel cell? No. The air spring drive system is sealed inside the tool and is powered by the 18V battery, so there is no compressor, hose, or gas cartridge to buy or haul.
• How many nails will I get per charge? Metabo HPT rates it at up to 1,170 nails per charge on the included 10.0Ah MultiVolt T-PWR Tabless battery.
• How fast can it fire? Up to 6 nails per second, according to Metabo HPT.
• Can the air spring be serviced in the field? Yes. Metabo HPT designed the line for on-site maintenance, with an optional Air Refill Valve (384002M), Maintenance Jig Kit (384003M), and a Wearable Parts Kit for replacing the driver blade and bumper without sending the tool to a service center.
• What nails does it take? 21-degree plastic-collated full round head framing nails, 2 in. to 3-1/2 in. long and 0.113 in. to 0.148 in. in diameter.
