The Milwaukee 23-Gauge 1-3/8" Cordless M12 Pin Nailer Kit (2540-21) is the most compact cordless pin nailer, combining precision and power to deliver the performance that professional carpenters and remodelers demand, without the hassle of a compressor hose or gas cartridge. The MILWAUKEE 23 Gauge Pin Nailer provides you with unmatched productivity and accessibility in tight spaces and confined corners with a lightweight, ergonomic design. 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. The M12 Pin Nailer drives 23-gauge headless pin nails ranging in length from 1/2” to 1-3/8” and features all-day run time with up to 750 pin nails per charge when paired with our M12 REDLITHIUM CP1.5 battery pack. This battery-powered pin nailer also features a magazine reload indicator, tool-free drive depth adjustment, reversible belt clip, LED light, battery fuel gauge, secondary work contact tip, and carries our industry-leading 3-year limited power tool warranty.
