Overview
A square drive head turns the socket on this battery operated Milwaukee ratchet, which the listing calls a fuel ratchet. The body is alloy steel with a brushed finish and a ratcheting action.
The reason to buy is power assisted turning in tight engine bays and under dashes, where a hand ratchet is slow. The limit is the muddled listing, with an unclear component line and an unlikely weight figure.
Who it's for
Automotive and equipment repair, where fasteners sit in cramped areas, is the setting. Heavy duty lug nut or suspension work calls for an impact wrench, because this is a ratchet with modest torque.
Pros and cons
- Powered ratcheting action
- Alloy steel body
- Long warranty period
- Square drive head
- Component list is unclear
- Battery inclusion not stated
- Not an impact wrench
Performance notes
A powered ratchet turns the drive for you, so the speed of a run of fasteners comes from the motor instead of your wrist. Torque is capped at the listed figure, which limits it to light and medium fasteners. Battery size sets run time.
