Milwaukee M18 FUEL 1/4-Inch Lockbolt Tool with ONE-KEY — Bare Tool
Product Overview
The Milwaukee M18 FUEL 1/4-Inch Lockbolt Tool with ONE-KEY (2661-20) is a cordless fastening tool engineered for high-volume lockbolt installation in transportation maintenance, heavy-duty fabrication, and other demanding applications. It delivers 4,500 lb of pull force and is designed to provide pneumatic-like performance without the need for an air compressor or hose.
Built around Milwaukee's POWERSTATE Brushless Motor, REDLINK PLUS intelligence, and M18 REDLITHIUM battery platform, the 2661-20 combines high pulling force with cordless mobility. Milwaukee states that the tool can install up to 1,200 1/4-inch aluminum Huck Magna-Grip lockbolts per charge when used with an M18 REDLITHIUM XC5.0 battery under the manufacturer's test conditions.
The integrated ONE-KEY technology adds digital tool management capabilities, including tracking, management, and security features. This makes the 2661-20 particularly useful for professional fleets where tool accountability and productivity are important.
This is the bare-tool configuration. Battery and charger are not included.
Key Features
4,500 lb Pull Force
The 2661-20 produces up to 4,500 lb of pulling force, giving it the capacity required for demanding lockbolt installation work.
Cordless Alternative to Pneumatic Systems
The M18 platform eliminates the need to run an air hose or position an air compressor at the work area. This can make the tool easier to transport and maneuver around vehicles and fabrication assemblies.
1.18-Inch Stroke
The tool provides a 1.18-inch stroke length, supporting the installation cycle required for compatible lockbolt fasteners.
Multiple Lockbolt Sizes
The 2661-20 is designed for 3/16-inch, 1/4-inch, and 3/8-inch lockbolts, with the 3/8-inch size requiring Milwaukee's Hucktainer Fastener Adapter (49-16-2661HT).
Supports Multiple Fastener Materials
The tool is specified for use with lockbolts made from aluminum, steel, and stainless steel, providing flexibility across different fastening requirements.
ONE-KEY Technology
ONE-KEY allows users to track, manage, and secure the lockbolt tool. This can be particularly valuable for contractors and fleet managers who need better control over high-value cordless equipment.
POWERSTATE Brushless Motor
Milwaukee's POWERSTATE Brushless Motor forms part of the M18 FUEL system and is designed to provide the power and durability required for professional applications.
Mandrel Collection System
The bare tool includes a mandrel collector for collecting spent mandrels during normal operation. Milwaukee also offers a separate M18 FUEL Blind Rivet & Lockbolt Mandrel Stopper (49-16-2661LBS) for applications where users want mandrels to drop from the back of the tool rather than be collected.

Performance
Milwaukee designed the 2661-20 to increase productivity in high-volume fastening environments. The company states that the tool provides installation speeds up to 50% faster than other cordless solutions and can install up to 1,200 1/4-inch aluminum Huck Magna-Grip lockbolts on a single M18 REDLITHIUM XC5.0 battery charge under specified test conditions. Actual productivity and battery runtime will vary according to fastener type, material, battery condition, temperature, and application.
What's Included
The 2661-20 bare-tool package includes:
1 × Milwaukee M18 FUEL 1/4-Inch Lockbolt Tool with ONE-KEY
1 × Mandrel Collector
1 × Bobtail Cap
1 × Belt Clip
Battery and charger are not included.
Recommended Applications
The Milwaukee M18 FUEL 1/4-Inch Lockbolt Tool is suitable for professional applications such as:
Transportation maintenance
Trailer and truck-body assembly
Heavy-duty vehicle repair
Metal fabrication
Structural fastening
Manufacturing and assembly operations
High-volume lockbolt installation
Applications where pneumatic equipment is inconvenient
Advantages of the Cordless Design
Using the M18 platform instead of a pneumatic setup can simplify the work area by eliminating the need for:
Air compressors
Pneumatic hoses
Compressor power connections
Hose routing around vehicles and assemblies
The cordless design also makes the tool easier to move between fastening locations, particularly in large vehicles, fabrication shops, and field-service environments.
ONE-KEY Tool Management
The integrated ONE-KEY system provides more than basic tool operation. Users can take advantage of supported digital management functions for tracking, managing, and securing the lockbolt tool. This is especially useful for businesses operating multiple tools across workshops, service vehicles, or job sites.
Accessories and Compatibility
For specialized applications, Milwaukee offers accessories for the 2661 platform. The 49-16-2661LBS Blind Rivet & Lockbolt Mandrel Stopper, for example, is designed specifically for the M18 FUEL 1/4-inch Lockbolt Tool and can help reduce tool length while allowing spent mandrels to drop from the rear of the tool.
For 3/8-inch lockbolts, the 49-16-2661HT Hucktainer Fastener Adapter is required.
Important Configuration Note
The 2661-20 is a bare tool, not a complete battery kit. An M18 REDLITHIUM battery and compatible charger must be purchased separately if you do not already own them.
Also, the 3/8-inch lockbolt capability should not be interpreted as standard out-of-the-box capacity—the specified Hucktainer Fastener Adapter (49-16-2661HT) is required for that size.
Why Choose the Milwaukee 2661-20?
The Milwaukee M18 FUEL 1/4-Inch Lockbolt Tool with ONE-KEY is built for professionals who need substantial pulling force without the restrictions of pneumatic equipment. With 4,500 lb of pull force, a 1.18-inch stroke, compatibility with multiple lockbolt sizes, and integrated ONE-KEY technology, it offers a practical cordless solution for demanding fastening environments.
For users already invested in the M18 battery platform, the 2661-20 bare tool provides the lockbolt installation capability without duplicating batteries and chargers.
