The Milwaukee 2878-20 M18™ FORCE LOGIC™ 12T Latched Linear Crimper is built for high-output electrical terminations where speed, access, and documentation matter. Its fully enclosed hydraulic system, POWERSTATE™ brushless motor, and REDLINK™ electronics deliver fast cycle times and consistent 12-ton crimping force across a wide temperature range. The inline body and 340° rotating head let technicians work one-handed in vaults, overhead, inside gear, or around cable trays. A quick-release, push-to-close latch pin makes it easy to swing around splices or switch connectors without juggling parts.
Predictive Force Monitoring (PFM™) measures force in real time to reach full pressure on every crimp, while a pre-crimp battery check confirms there’s enough charge to complete the cycle. With full compatibility for industry-standard U-dies, crews can keep using the die sets already on the truck. Paired with EXACT™ 12T U-Dies, the tool produces UL Classified crimps per UL 486A-B on #8–750 MCM copper and on dual-rated color-coded lugs and splices from leading brands. ONE-KEY™ integration records and stores crimp data for professional reports and traceability—useful for QA, commissioning, and maintenance documentation.

Teams working with large copper or dual-rated connectors need a cordless hydraulic crimping tool that reaches full force quickly and verifies each cycle. The 2878-20’s inline design improves access inside enclosures and overhead runs, while the 340° head helps orient dies around bus, bars, and bundled conductors. For QA-driven environments—utilities, industrials, and renewable installations—PFM™ and ONE-KEY™ reduce rework by confirming pressure and capturing crimp records. U-die compatibility protects existing die investments, and the pre-crimp battery check helps prevent mid-cycle faults that cost time on energized shutdown windows.

Why Professionals Choose the Milwaukee M18 FORCE LOGIC 12T Latched Linear Crimper
Electrical crews choose this cordless hydraulic crimping tool for its proven combination of speed, access, and verification. The inline 12-ton crimper with a 340° head reaches tight terminations in switchgear and inside panels where a C-head tool struggles. PFM™ and the green LED confirm each cycle hits full pressure, which helps reduce rework on feeders and minimizes callbacks after energization. Because it accepts U-dies, teams can keep using their existing die sets; pairing it with EXACT™ 12T U-Dies delivers UL 486A-B Classified crimps on #8–750 MCM copper and dual-rated connectors. With ONE-KEY™, installers export crimp data for commissioning reports or asset records. For technicians who want a cordless crimper that works across the M18™ platform, this model provides the performance and documentation needed on commercial, industrial, and utility jobs.
Milwaukee 2878-20 M18 FORCE LOGIC 12T Latched Linear Crimper – Tool Only Notes for Buyers (quick tips)
- Match die to connector manufacturer, size, and color code; verify with spec sheets before crimping.
- Use the pre-crimp battery check—swap packs if prompted to avoid incomplete cycles.
- For UL Classified results, use Milwaukee® EXACT™ 12T U-Dies and approved lugs/splices as listed.
- Keep the latch pin clear of debris so the push-to-close action stays smooth
