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