Makita 18V LXT® 21° Full Round Head 3-1/2" Framing Nailer (XNB03Z): Cordless Power for Serious Framing

When it comes to framing, power and reliability are non-negotiable. The Makita 18V LXT® 21° Full Round Head 3-1/2" Framing Nailer (model XNB03) delivers both—without the need for a compressor or hoses. If you’re looking to cut the cord and get serious work done, this tool is built for the jobsite.

Cordless Convenience, Pneumatic Performance, Winning Nailer

The XNB03 runs on Makita’s proven 18V LXT® battery platform, giving you true cordless freedom. But don’t let the lack of a compressor fool you—this nailer drives full round head framing nails into dense engineered lumber with the kind of power you’d expect from a pneumatic tool. One 6.0Ah battery (sold separately) delivers up to 1,000 nails per charge, so you can keep working without constant interruptions.

Built for the Real World

  • Versatile Firing Modes: Switch between sequential nailing for precision or bump fire for speed with the two-mode selector.
  • Anti-Slip Nose: Get controlled, accurate nailing at almost any angle—even in tough spots.
  • Tool-Less Depth Adjustment: Dial in the perfect flush or countersunk finish without hunting for extra tools.
  • Rear Lock-and-Load Magazine: Holds 41 nails for fewer reloads. Need more? There’s an optional extended magazine (sold separately) that boosts capacity to 97 nails.

Practical, Jobsite-Ready Features

  • Anti-Dry Fire Mechanism: Prevents firing blanks, protecting both your tool and your work.
  • Built-In LED Light: Illuminates your workspace for safer, more accurate nailing.
  • Ergonomic Handle: Rubberized soft grip and a balanced 11.9 lb weight (with battery) mean less fatigue on long days.
  • Belt Hook and Extra-Wide Tool Hook: Secure the nailer when not in use—no more awkward juggling.

Built for Makita’s Expanding 18V LXT® System

The XNB03 is part of the world’s largest cordless tool system powered by 18V lithium-ion batteries. Makita’s Star Protection Computer Controls™ ensure your tool and battery communicate in real time to prevent overload, over-discharge, and overheating—maximizing both performance and battery life.

Who’s It For?

This framing nailer is a solid pick for professional framers, remodelers, and serious DIYers who want pneumatic power without the compressor. It’s designed for framing, sheathing, subfloor, roof decking, and more—especially when you need to move fast and work efficiently.
