Milwaukee M12 1/4 in Cordless Hex Impact Driver - Compact Power

In this review of the Milwaukee 2462-20 M12 12-Volt 1/4 in Cordless Hex Impact Driver, the bottom line is simple: it is a compact, torque-packed bare tool best for tradespeople and DIYers who need high punch in a lightweight package. The standout reason to buy is its combination of 1,000 in-lbs of torque and a 2,500 RPM motor in a 1.9 lb body, which lets users drive fasteners into tough material without carrying a bulky drill. This review focuses on practicality, control, and everyday jobsite value rather than battery kits or accessories.

Key Features

• 1,000 in-lbs torque: Delivers strong impact force so users can drive long screws and lag quickly into dense materials with fewer stalls.
• 2,500 RPM motor: Provides fast no-load speed for quicker bit work and reduced overall task time on repetitive fastening jobs.
• Variable speed control: Lets users modulate power to avoid overdriving and to extend runtime when used with M12 batteries.
• Ergonomic grip: Improves comfort and reduces wrist strain during extended use, which is helpful on prolonged fastening runs.
• Keyless 1/4 in hex chuck: Makes bit changes fast and easy so users spend less time swapping accessories and more time working.
• Built-in LED and fuel gauge: On-board light improves visibility in tight, dark spaces and the battery fuel gauge helps manage work sessions (battery sold separately).

Who It's For

The Milwaukee M12 2462-20 is aimed at contractors, cabinetmakers, electricians, and serious DIYers who need a compact impact driver that still offers real torque for fastening in wood, metal, and composite materials. Its light weight and short length make it well suited for overhead work and tight access points where a full-size 18V tool would be cumbersome.

It is not a complete kit: the tool is sold bare, so buyers who want an all-in-one package with battery and charger included should look at kit offerings or bundle purchases. Also, users who require very high sustained torque for heavy demolition should consider larger 18V or cordless models instead.

Pros & Cons

Pros

• Compact 1.9 lb design is easy to handle and reduces fatigue during long runs.
• High torque output of 1,000 in-lbs provides strong fastening capability for its size.
• Variable speed and keyless hex chuck give good control and fast bit changes.
• Built-in LED and on-board fuel gauge add practical jobsite conveniences.

Cons

• Sold as a bare tool, so batteries and charger must be purchased separately.
• Smaller M12 platform limits runtime compared with larger battery platforms for very long continuous work.
