Overview
Driving fasteners with a cordless ratchet, this Milwaukee kit bundles the tool with a lithium ion battery, a charger, an adapter and a carrying case. The listing names the battery as an M12 red lithium pack.
The kit bundle covers the power side, which spares a separate battery purchase. The limitation is that torque, head size and drive size are not given, so check them against your fasteners.
Who it's for
A first cordless ratchet purchase, where a battery and charger are needed anyway, suits the kit. Those who already have batteries and want only the tool, or who need documented torque, should look elsewhere.
Pros and cons
- Battery and charger included
- Carrying case supplied
- Cordless lithium ion power
- Torque not listed
- Drive size unspecified
- Head type not stated
Performance notes
Speed is set by the battery-driven motor, listed as a maximum rotational speed. Run time depends on the lithium ion battery supplied and on how often it is recharged. Torque and head size are not described.
