Milwaukee M12 Cordless Rivet Tool 2550-20 (Bare) — Compact 6.5" Body, 2,000 lb Pull Force

The Milwaukee M12 2550-20 is a compact cordless rivet tool that delivers up to 2,000 lbs of pull force and the capacity to set 450 1/8" steel rivets on a single 1.5 Ah charge.

Designed as a portable alternative to pneumatic riveters, the M12 2550-20 (bare tool) combines strong pulling power, a short 0.8" stroke, and a compact 6.5" length to reach tight spaces while cutting operator effort. It’s part of Milwaukee’s M12 battery family, letting crews reuse existing batteries to power a wide range of cordless solutions. The tool’s construction focuses on durability for frequent jobsite use and offers extended runtime compared with earlier cordless riveters.

What sizes and materials can this rivet tool handle?

The 2550-20 accepts common blind rivet sizes and is rated to set stainless and steel rivets up to 3/16" diameter. It supports 3/32", 1/8", 5/32", and 3/16" rivets, covering most sheet metal and fabrication applications where blind riveting is required.

• Compatible rivet diameters: 3/32", 1/8", 5/32", 3/16"
• Capable of installing stainless and steel blind rivets
• Suitable for typical metal-joining tasks on-site or in shop

How long will one battery charge last during typical use?

Runtime varies by rivet size and material, but Milwaukee rates the tool to install approximately 450 1/8" steel rivets on a single 1.5 Ah M12 battery charge. Larger rivets and harder materials reduce that count, while higher-capacity batteries extend productivity.

• Approx. 450 1/8" steel rivets per 1.5 Ah charge (manufacturer figure)
• Longer runtime with 2.0 Ah, 3.0 Ah or higher-capacity M12 batteries
• Real-world results depend on rivet type, operator cycle time, and load

How does this tool improve productivity and user comfort?

By replacing manual hand tools and eliminating hoses and compressors, the M12 rivet tool reduces physical strain and streamlines setup. Milwaukee reports a greater than 60% reduction in muscle effort compared with hand riveting, allowing faster cycles and less fatigue on repetitive jobs.

• Cordless design removes compressor and hose requirements
• Compact 6.5" body provides access in confined areas
• High pull force (up to 2,000 lbs) handles tough rivet installs

Is this tool durable enough for regular jobsite use?

The 2550-20 is engineered for long life under jobsite conditions and claims roughly double the lifespan of earlier cordless rivet models. Rugged construction and proven M12 platform compatibility make it a practical choice for trade professionals needing a dependable cordless riveter.

• Designed for extended service life versus previous cordless solutions
• Robust housing and internal components for common jobsite wear
• Works with Milwaukee M12 batteries and chargers for convenience

Who this is for: The Milwaukee M12 2550-20 bare tool suits tradespeople, maintenance technicians, and fabrication teams who need a portable, high-force blind riveter without a compressor. It’s ideal for crews already invested in the M12 battery system who want to add compact, cordless riveting capability for installations in tight spaces or where hose-free setups speed work.
