Uncover the full potential of this product

The Milwaukee M12 Cable Stapler Kit (model 2448-21) is a high-productivity cordless stapling solution built for electricians and low-voltage installers. It uses 1″ insulated staples to fasten NM-B cable (14, 12, 10 AWG) and low voltage data / communication wiring, reliably sinking staples to the proper depth via a coil-spring mechanism. Its compact, lightweight design allows easy access in tight stud bays or overhead installs, and features such as moveable cable guides, a staple viewing window, LED work light, and dry fire lockout enhance usability and safety. On a full charge with the included M12 CP2.0 battery, it can drive up to 1,200 staples.
