M18 FUEL™ Duplex Nailer Kit

The Milwaukee M18 FUEL Duplex Nailer Kit (model 2844-21) is a cordless framing nailer built for assembling concrete formwork, driving nails into all wooden formwork materials at firing rates up to 4 nails per second. As a “-21” kit it ships with the tool plus battery and charger. It runs on a nitrogen air spring paired with a POWERSTATE Brushless motor and REDLINK Intelligence, and joins the M18 system of 200+ solutions.

What it does well

• Fires up to 4 nails per second with nitrogen air spring drive and a POWERSTATE Brushless motor
• Sinks up to 800 nails per charge when paired with an M18 REDLITHIUM 5.0Ah battery
• Tool-free depth-of-drive adjustment and a tool-free jam-clearing latch minimize downtime
• Nail placement indicator, dry-fire lockout, LED work light, flattop design, ergonomic glove-friendly handle, and a belt & rafter hook

Is this the right nailer for you?

This is a purpose-built duplex nailer for concrete formwork crews who set and strip forms repeatedly — the double-head duplex design leaves nails proud for easy removal. It is only compatible with Milwaukee Collated Duplex Nails (MDP8D-2000 and MDP16D-2000), so confirm you can source those before buying. If you need a general framing nailer for permanent nailing, look elsewhere in the M18 lineup.
