Milwaukee 2661-20 M18 Brushless Lockbolt Tool One-key

Product Description

The MILWAUKEE 2661-20 is a cordless M18 FUEL brushless lockbolt tool built for industrial fastening in demanding shop and assembly environments. Powered by a POWERSTATE brushless motor delivering 4,500 lbs. of pulling force, it installs Magna-Grip, C6L, C120L, Bobtail, and Hucktainer lockbolt fasteners without requiring air compressors or hoses. ONE-KEY compatibility allows tool tracking and management from a mobile device. REDLINK PLUS intelligence protects the tool and battery from overloads, overheating, and over-discharge. The tool weighs 5.9 pounds and ships as a single unit without a battery.

This tool is designed for structural assembly, manufacturing, and heavy construction applications where pneumatic infrastructure is unavailable or impractical. It installs up to 1,200 aluminum Magna-Grip lockbolts per charge on an M18 REDLITHIUM XC5.0Ah battery (sold separately). With an optional adapter (49-16-2661R), the tool also installs 3/16 inch through 9/32 inch blind rivets in aluminum, steel, and stainless steel. With the Hucktainer Fastener Adapter (49-16-2661HT), Hucktainer fasteners can also be set. The all-metal gearcase and impact-resistant plastics with protective rubber overmold are rated for corrosive and high-cycle environments.
