The new Milwaukee M12 23 Gauge Pin Nailer is their most compact cordless pin nailer to date, delivering the precision and power that professional carpenters and remodelers demand, without the hassle of a compressor hose or gas cartridge. This Pin Nailer provides you with unmatched productivity and accessibility in tight spaces and confined corners with the most lightweight and ergonomic design among its competitors.

Key Features:

Compact Design and Portability

Milwaukee M12 Pin Nailer applying trim in a hard to reach, compact corner.

23-gauge pin nailers are essential for the installation of crown molding, toe kick, shoe molding, mitered corners, returns, and other decorative pieces of trim. These applications often require reaching into compact areas, which can be difficult if your tool is clunky and heavy. The M12 23GA Pin Nailer ($199) solves this issue by being the most compact and lightweight model available. It is designed with its core users in mind to ensure that all of the common issues that carpenters, woodworkers, remodelers, and general contractors face when working with pin nailers are eliminated. Because of its compact size and precision point tip, users can reach into confined spaces and achieve a clear line of sight for accurate nail placement. The LED light on top of the nailer provides enhanced visibility in low light applications. Weighing in at only 3.8 lbs. with a battery included, this tool is also lightweight, creating less fatigue during use.


Consistency is key in pin nailing applications, and this Milwaukee Pin Nailer does not disappoint. The nitrogen air spring mechanism allows the nailer to consistently sink pin nails at proper depth into hard or softwoods while leaving small, clean nail holes. The double-action trigger and non-marring precision point tip allow you to perform sequential driving and accurate pin placement into delicate trim pieces. The dry-fire lockout feature prevents misfires and workpiece damage. Having a tool that can effectively sink sub-flush holes will require less follow up from the carpenter or painter on the job.

Milwaukee M12 23 Gauge Pin Nailer Features: LED Light, Nitrogen Air Spring Mechanism, Double-Action Trigger, Battery Fuel Gauge, Tool Free Drive Depth Adjustment, Magazine Reload Indicator.

Unmatched Power Output

The M12 Pin Nailer drives 23-gauge headless pin nails ranging in length from 1/2” to 1-3/8”.

This battery-powered pin nailer also features a magazine reload indicator, tool-free drive depth adjustment, reversible belt clip, battery fuel gauge, and secondary work contact tip. It is designed to be a full pneumatic replacement, built powerful enough to consistently nail into hardwoods, regardless of material or nail size. It is an all-around great tool for the everyday user because it is reliable and guaranteed to deliver consistent results every time.
