Uncover the full potential of this product

The Milwaukee M12 23 Gauge Pin Nailer Kit (2540-21) is a compact, cordless finishing tool engineered for precision trim work, molding, cabinetry, and delicate wood joinery. Using a nitrogen-powered air spring mechanism, it achieves consistent depth control comparable to pneumatic systems without hoses, gas cartridges or compressors. Its small form factor and ergonomic design allow access into tight corners and confined spaces. The kit includes the tool, one REDLITHIUM CP1.5 battery, charger, and a contractor bag making it a ready-to-go solution for finishing professionals.

Ideal for carpenters, woodworkers, interior finish crews, and remodelers, this pin nailer is built to deliver clean performance and reduce downtime on the job.

    • The nitrogen air spring mechanism drives 23-gauge headless pin nails reliably into both softwoods and hardwoods.


  • Wide Nail Length Compatibility

    • Supports pin lengths from ½″ to 1⅜″ (12.7 mm to 34.9 mm).


  • Long Runtime

    • Up to 750 pin nails per charge when used with the included M12 REDLITHIUM CP1.5 battery pack.


  • Tool-Free Drive Depth Adjustment

    • Easily fine-tune drive depth without tools, for flush or just-below-surface pin finishing.
