Milwaukee M12 3/8” Crown Stapler (2447-20)

The Milwaukee 2447-20 M12™ Cordless 3/8" Crown Stapler is designed to provide fast, consistent fastening performance while reducing the effort required by traditional hand staplers. Whether you're installing insulation, house wrap, vapor barriers, upholstery, or completing general repair projects, this compact cordless stapler offers the mobility and control needed to work efficiently.

The stapler drives 3/8-inch flat crown T50® staples ranging from 1/4 inch to 9/16 inch. Its lightweight, ergonomic design improves access in confined areas, while the easy-to-squeeze trigger helps reduce user fatigue. Integrated sequential and contact actuation modes, a power adjustment dial, dry-fire lockout, and a slotted magazine provide greater control, productivity, and consistent staple placement across different materials.

The 2447-20 is the tool-only model and is compatible with all Milwaukee M12™ batteries. Battery, charger, and staples are sold separately. For detailed technical information, compatible staple sizes, package contents, and warranty details, please refer to the sections below.
