Milwaukee M12 Crown Stapler 2447-21

Milwaukee M12 Crown Staple Gun 2447-21 Features:

The Milwaukee M12 Crown Stapler 2447-21 features a large, heavy duty, aluminum body with a chrome plated finish. The body is made from high strength steel and has a solid feel in your hands. The body is finished off with two rubber grips that are comfortable to hold.

A push button plunger release allows easy access to the tool head when needed. The tool head is a single action, double action (SA) model that operates smoothly and reliably. The tool head has a built in safety feature which prevents accidental disassembly if dropped or bumped into while operating. The tool head features a spring loaded plunger that releases the tool from the body when fully inserted. The tool head is equipped with a locking mechanism that keeps it securely in place when not in use.

The Milwaukee M12 Crown Stapler 2447-21 comes with a durable nylon carrying case that is designed to protect the tool from damage during transport. The case has a padded interior and has two elastic straps to secure the tool inside. Two additional elastic straps are included for attaching the case to your belt loop or backpack strap.

The kit also comes with a convenient lanyard, a spare anvil, and six extra staples.

The tool can be connected to any M12 battery or a USB-compatible battery with the correct adapter (sold separately). A two hour charge time yields up to 50 minutes of operating time on a single charge. The M12 line of lithium-ion batteries are among the lightest and most compact 18V batteries in the market.

They have a 2.0Ah, 4.0Ah, 5.0Ah, and 6.0Ah capacity and can be linked in parallel to increase run time up to a maximum of 10 batteries. (Sold separately)

The M12 Crown Stapler 2447-21 is perfect for contractors, plumbers, refrigeration technicians, and anyone else that works with sheet metal or other types of hard material on a regular basis.

Who is the product designed for?

The kit is designed for professional users that need a high quality stapler. It can be used for a wide range of stapling needs and the large capacity staple cartridge can handle all but the most demanding jobs. The tool can easily be reloaded with a new staple cartridge when needed. The kit includes a durable carrying case and enough accessories to get the job done.

What are the advantages?

The tool is rugged, powerful, and made to last. It can be reloaded quickly with a fresh staple cartridge when needed. A large capacity battery delivers an excellent time to empty. The kit comes with two 2.0Ah batteries, a double battery charger, and two additional staple cartridges, giving you over an hour of operating time without needing to reload.

What are the limitations?

The tool is a bit heavier than some of the newer electric options on the market. The tool also has a short reach compared to pistol grip tools. The body is also a bit wide for really narrow spaces.
