Overview
A mechanic or serious DIYer gets a nylon-bodied cordless impact wrench that pairs a built-in light with a mode meant to prevent fastener run-off. It is sold as the wrench alone.
The reason to look at it is the extra control features around the torque. The limitation is odd data, including a speed entry and a compatible device entry that make no sense for this tool.
Who it's for
A technician with compatible batteries who values speed settings to avoid snapping bolts. A buyer with no batteries must source them separately.
Pros and cons
- Four speed settings
- Built-in work light
- Overtightening control mode
- Battery not included
- Speed entry looks wrong
- Compatible device entry looks wrong
Performance notes
The control mode limits how long the impact stays active, which helps prevent overtightening and fastener run-off. Speed settings change how aggressively torque builds, and the light shows the work area in dark bays.
