The Milwaukee M12 Cable Stapler delivers unmatched stapling performance in the most compact battery-powered solution leading to a faster, more efficient rough-in process. The compact, lightweight design provides users with access to tight stud bays and improved ergonomics when stapling overhead or during difficult-to-reach situations. Moveable cable guides ensure proper alignment and the coil-spring mechanism consistently sinks the staples to the appropriate depth when fastening NM-B Sheathed Cable (14, 12, 10 AWG) and low voltage cables, supporting peak stapling productivity. Only compatible with the Milwaukee 1 in. insulated staples (sold separately), the M12 Cable Stapler gives the user the run-time needed to sink up to 1,200 staples on a fully charged M12 CP2.0ah battery. Our M12 REDLITHIUM HIGH OUTPUT CP2.5 Battery Pack delivers 25% more power and runs 25% cooler vs our other M12 REDLITHIUM CP battery packs. This increased performance of the lithium-ion battery gives you the same power and runtime of an M12 REDLITHIUM XC battery in a lighter and more compact package.
