Milwaukee 2979-20 M18 FORCE LOGIC 6T Latched Linear Utility Crimper – Tool Only

The Milwaukee 2979-20 M18™ FORCE LOGIC™ 6T Latched Linear Utility Crimper is designed for overhead and underground utility terminations where uniform results, access, and control are essential. Its inline body and 340° rotating head fit easily between conductors, around hardware, and inside tight enclosures. An enlarged trigger, slim grip, and dual electronic release buttons let right- or left-handed users operate the tool one-handed while wearing Class 3 gloves. The latched head opens wide, then secures positively so only the intended conductor is crimped, reducing setup errors on energized-adjacent work.

Predictive Force Monitoring (PFM™) measures force throughout each cycle to reach full pressure and maintain consistent output over the life of the tool, producing repeatable, uniform crimps. A pre-crimp battery check confirms the pack has enough charge to finish the cycle. Built with fully enclosed, high-speed hydraulics, a POWERSTATE™ brushless motor, and REDLINK™ electronics, the 6-ton system delivers fast 3-second cycles and reliable operation from −4°F to 140°F. Using the industry-standard W-Style die interface and D3 die index marking, the tool supports a wide range of utility connectors, including up to 4/0 line taps. ONE-KEY™ integration records and stores crimp data to support QA, commissioning, and maintenance records.

Utility and service crews value a hydraulic crimping tool that is quick to position and simple to verify. The 2979-20’s inline, balanced body and 340° head improve control from the bucket or in a handhole, while the latched design secures the work so stray strands don’t enter the die. Force monitoring confirms full pressure without guesswork, and the green LED provides instant feedback before wrapping and moving on. ONE-KEY™ stores crimp data for reports that many utilities now require, helping supervisors close out jobs with clear documentation. With W-Style die compatibility and the D3 index, teams can use the dies they already stock and still get consistent results on taps up to 4/0.

Why Professionals Choose the Milwaukee M18 FORCE LOGIC 6T Latched Linear Utility Crimper

Line crews pick this M18™ utility crimper for uniform, verifiable results with less setup time. The inline body and rotating head reach conductors in crowded crossarms and cabinets where larger C-head tools struggle. PFM™ confirms full force on each cycle, and the green LED gives an immediate pass/fail cue before taping or heat-shrinking. Using W-Style dies with the familiar D3 die index keeps operations consistent across trucks and shifts. For contractors standardizing on the M18 battery platform, the 6-ton crimper offers fast, 3-second cycles and reliable performance in cold mornings and hot afternoons. With ONE-KEY data logging, supervisors can produce crimp records for closeout packages and audits without extra steps—helping crews finish work safely and on schedule.

Milwaukee 2979-20 M18 FORCE LOGIC 6T Latched Linear Utility Crimper – Tool Only Notes for Buyers (quick tips)

• Die/Connector Matching: Verify W-Style die part numbers against the connector manufacturer’s chart; the D3 die index should match your work print.
• Dry Fit & Align: Seat conductor and connector fully, confirm alignment, then close the latch. Misalignment is the most common cause of uneven crimps.
• Keep the Latch Clean: Brush debris from the latch channel; avoid heavy oils that collect dust.
• Use the Pre-Crimp Battery Check: Swap packs if low to prevent mid-cycle dropouts.
• Wait for Green LED: If no LED, use the electronic release and inspect—don’t re-crimp a questionable termination without following procedure.
• Multi-Crimp Sequence: Follow the connector maker’s sequence (center-out or far-to-near). Mark each crimp with a paint pen.
• Head Orientation: Rotate the 340° head to keep the tool inline with the conductor and avoid side-loading.
• Temperature Practices: At −4°F to 140°F, warm batteries in cold weather; shade tools in high heat. Carry a spare pack.
• ONE-KEY™ Naming: Use a clear job/tag convention (feeder ID, pole #, date) so logs map to closeout packages.
• Post-Crimp Check: Confirm die index impression and expected flash. Perform a tug test per spec before tape/heat-shrink.
• Maintenance: Wipe the ram/head after dusty work; inspect die seats for burrs; replace worn dies promptly.
• Connector Prep: For AL connectors, use the proper wire brush and oxide inhibitor; for Cu, straighten/clean strands before insertion.
• Work Near Energized Lines: The latched head helps isolate the target conductor; still use approved blankets/barriers and maintain MAD.
• Storage: Stow with dies removed and latch closed; avoid pressing the release buttons in transit.
• Training: New users should practice on scrap conductor to learn the release feel and correct crimp appearance.
