M18 FUEL™ 15 Gauge Finish Nailer Kit

The Milwaukee M18 FUEL 15 Gauge Finish Nailer Kit (2839-21CT) is a cordless finish nailer that drives 15GA DA-style finish nails in hardwoods and softwoods with no compressor, hose, or gas cartridge. It uses a nitrogen air spring mechanism paired with a POWERSTATE Brushless Motor and REDLINK PLUS Intelligence for consistent, pneumatic-like nailing. As a “-21CT” kit, it ships with an M18 REDLITHIUM battery and charger.

What it does well

• Sinks 15GA DA-style finish nails to depth in both hard and softwoods, leaving clean holes for easy filling.
• Fires up to 3 nails per second and up to 750 nails per charge on an M18 REDLITHIUM CP2.0 battery.
• 110-nail magazine capacity with sequential and contact actuation firing modes.
• Tool-free depth adjustment, tool-free jam-clearing latch, LED work light, reversible belt hook, and on-magazine tip storage.

Is this the right finish nailer for you?

This is built for professional carpenters and remodelers running trim, crown molding, and baseboards who want pneumatic-style performance without a compressor and hose. It runs on the M18 system, so it’s a strong fit if you already own M18 REDLITHIUM batteries. Choose the “-20” bare-tool version instead if you only need the tool and already have batteries and a charger.
