Overview
Not a drill driver, this Milwaukee 2663-20 is built for heavy fastening with a socket end and battery power. The body combines alloy steel and aluminum with a painted red finish.
The reason to buy is the very high torque in a tool with an alloy steel and aluminum body, enough for stubborn bolts. The limitation is that the listing says little about contents, so battery, charger and speed settings are unknown.
Who it's for
Mechanics, equipment techs and serious home garage users will use the torque on seized fasteners. Anyone driving small screws or working on delicate parts should choose a screwdriver or compact driver.
Pros and cons
- High torque rating
- Cordless battery power
- Metal alloy body
- Long limited warranty
- Box contents not listed
- No speed settings described
Performance notes
An impact tool delivers torque in short bursts, so it loosens stuck fasteners that steady rotation would not. Battery condition affects how much of the rated torque is available. Socket fit and the quality of each socket decide how well the force reaches the fastener.
