Summary

An 18V M18 FUEL 3/4 inch high-torque impact wrench with ONE-KEY, rated up to 1,200 ft-lbs fastening and 1,500 ft-lbs nut-busting, sold as a bare tool. Check the batteries and the accessories before you buy: it needs separate M18 packs, and the protective boot sold near it fits a different wrench.

Strengths

  • Up to 1,200 ft-lbs fastening and 1,500 ft-lbs nut-busting torque.
  • A compact 8.59 inch body for a high-torque wrench.
  • A POWERSTATE brushless motor with REDLINK PLUS protection.
  • ONE-KEY saves 4 profiles to the tool and tracks it within 100 ft.
  • A friction-ring 3/4 inch anvil with a thru-hole.
  • A rubber overmold that resists oils, greases and solvents.

Weaknesses

  • A bare tool: no battery, charger or case.
  • No independent instrumented torque test of this exact model was found.
  • No owner discussion data was found to draw on.
  • The impact rate differs across retailer spec sheets, from 2,100 to 2,400.
  • ONE-KEY adds little for a single-user owner.
  • The 49-16-2864 protective boot does not fit this model.

Torque and ONE-KEY

Milwaukee rates the 2864-20 at up to 1,200 ft-lbs fastening and 1,500 ft-lbs nut-busting in an 8.59 inch body, driven by a POWERSTATE brushless motor. Nobody has published an instrumented torque measurement to confirm those figures, and owner discussion was not available, so they stand as claims. ONE-KEY connects the tool to a smartphone for profile customization, tracking and fleet management; it holds up to 4 profiles in memory so the phone is not needed during use, tracks the tool within 100 ft, and supports lock-out and remote shut-off. For a single owner, that matters far less than it does for a fleet.

Batteries and kit choice

The bare tool includes no battery, charger or case, so the entry cost depends on whether you already own M18 packs. If you do not, the kit is the practical route: Ohio Power Tool lists the 2864-22R at $679, and Home Depot lists a tool-plus-5.0Ah bundle at $589. Buyers should also watch accessories: the 49-16-2864 protective boot sold near this wrench fits only the 1-inch 2867-20, not this model.

Is it worth it?

Northern Tool and Ohio Power Tool list the bare tool at $429. That is professional money for the high-torque class, and it makes sense for an existing M18 owner who needs 3/4 inch power in tight spaces. Without M18 batteries the kit at $589-679 is the real price. With no independent torque data and no owner reports to lean on, the case rests on Milwaukee’s reputation and the M18 ecosystem, so compare against DeWalt and Ingersoll Rand on measured torque before committing.

Which model this is
