Our Take on the Milwaukee 3453-20 12V Fuel Impact Driver
This impact driver is a game-changer for tight spaces. It's compact,5' length and 7.6' height (with a 2.0 Ah battery) make it easy to maneuver in awkward angles, while the brushless motor delivers smooth, powerful performance. The three LED lights are a lifesaver for low-light jobs,casting bright illumination without annoying glare.It's lightweight at just 2 lbs, so it stays on my tool belt all day without causing strain. The Mode 34 drive control lets me switch between high-speed and high-torque settings,with a dedicated self-tapping mode that's a time-saver for fastening screws. I've used it for installing trim and cabinetry, and it's surprisingly efficient for a subcompact tool.
The brushless motor is a standout feature-unmatched in the subcompact class. It handles tough fastening tasks, like driving long screws into dense materials, without overheating. The LED lights are intuitive and add visibility where it's needed most, though they might be too bright for some. The three modes (including the self-tapping setting) make it versatile for various jobs. However, it's a bare tool, so I had to buy a battery separately, which adds to the cost. Still, the bite-sized design and premium build justify the extra investment.
Pros:
- Compact and lightweight for easy portability
- Brushless motor offers consistent power and longer runtime
- Three LED lights improve workspace visibility
- Multiple drive modes (including self-tapping) for efficiency
Cons:
- Requires separate battery purchase
- Slightly less torque then larger 18V models
Key Features | Pros | Cons |
---|---|---|
Brushless motor (up to 1,500 in-lbs. torque) | Fast, reliable performance; smooth acceleration | Higher torque required for heavy-duty tasks |
Three LED work lights | Excellent visibility in dark or cramped areas | LED brightness may be too intense for some users |
Mode 34 drive control (3600 RPMs) | Adjustable speed for precision and power | Less ergonomic than some high-end models |
2 lbs. weight | Reduces fatigue during prolonged use | Tool design may not suit extended overhead work |
Key Features That Stand out
The Milwaukee M12 1/4" Hex Impact Driver is a game-changer for tight spaces.Its compact size-just over 5 feet long and 7.6 inches tall with the included battery-makes it easy to maneuver in cramped areas, like installing trim or working under cabinets. The brushless motor delivers strong 1,500 in-lbs. of torque, and the 3600 RPMs in Mode 34 feel snappy enough for quick work. The three LED lights are a lifesaver, cutting through shadows and giving clarity even in low-light corners. I've used it for both drilling and driving, and the dedicated self-tapping screw mode simplifies tasks without needing extra attachments.
Lightweight at 2 lbs, it's cozy for extended use, reducing fatigue during a full day of work. The drive control options let you adjust speed and power depending on the job-perfect for delicate vs. heavy-duty tasks. I appreciated how it stays cool under pressure, thanks to the brushless motor, and how it doesn't lag behind larger impact drivers in performance. The tool's design prioritizes portability, and the LED lights make it feel like a high-end setup despite its small size. It's a versatile addition to my toolkit, especially for projects where space is limited.
Pros include its compactness, powerful torque, and user-pleasant modes. The LED lights and ergonomic grip are also standout features. However, it's important to note the 12V battery is sold separately, which might be a drawback if you need a complete setup. While it handles most tasks well, it's not as robust as higher-voltage models for extreme applications. Still, for everyday use and accessibility, it's hard to beat. A great option for DIYers or professionals who value portability and efficiency.

Design and Usability Considerations
The Milwaukee M12 1/4" Hex Impact Driver is a powerhouse in its class, delivering remarkable speed and torque without sacrificing portability. Its compact design makes it perfect for tight spaces, and the brushless motor ensures longer runtime and less heat buildup compared to traditional models.I found it incredibly efficient for driving screws and fastening hardware, especially in projects where mobility is key. The included three LED lights brighten dim work zones, which is a huge plus when working in low-light conditions or under a vehicle. Combined with the 3600 RPMs in Mode 34 and a dedicated self-tapping screw setting, it feels like a versatile tool for both casual and professional use.
What really stands out is how lightweight it is-just 2 lbs-reducing fatigue during extended work sessions. the ergonomic grip and balanced weight distribution make it comfortable to handle, even when working overhead or in awkward positions. However, the brushless motor does require a compatible M12 battery (sold separately), which I initially thought might be a limitation but ultimately adds versatility in choosing the right power source. while it's not the most powerful impact driver on the market,it does a great job for its size and meets most DIY and small-scale construction needs without hesitation.
