Who Should Buy This Drill
This Milwaukee M18 model suits homeowners tackling DIY projects, furniture assembly, and general household repairs. It also works well for contractors and professionals performing light to medium-duty drilling and fastening tasks on job sites. The compact size makes it ideal for users who need maneuverability in tight spaces without sacrificing power.
When This Drill Excels
The dual-speed transmission shines when switching between high-speed drilling in wood and low-speed, high-torque fastening for screws and bolts. The variable speed control prevents over-driving fasteners into delicate materials. Cold-weather operation down to 0 degrees F makes this drill reliable for outdoor winter projects when other cordless tools fail.
Important Considerations
This is a standard drill driver, not a hammer drill, so it cannot handle masonry or concrete drilling. Users who need maximum runtime should consider upgrading to larger capacity batteries, though the included 1.5Ah battery provides impressive performance for most applications. The direction lock can be accidentally engaged, so familiarize yourself with the thumb placement to avoid accidental engagement during operation.
Value and Long-Term Use
Milwaukee's Redlithium battery technology and Redlink Intelligence protection justify the investment through extended tool life and reliability. The included hard case protects your investment during transport and storage. Consider purchasing additional batteries to maintain continuous workflow on extended projects without waiting for recharge cycles.
Pros
- Impressive torque for its compact size
- Fast bit changes with keyless chuck
- Lightweight and ergonomic for all-day use
- Compatible with Milwaukee's extensive M18 battery system
Cons
- Tool only, no battery or charger included
- Brushed motor may require more maintenance than brushless models
- Some users report receiving units in non-retail packaging; verify seller before purchase
The Milwaukee M18 Compact Drill Driver (model 2606-20) is a cordless powerhouse designed for both DIY enthusiasts and professional tradespeople. This tool-only unit integrates seamlessly into Milwaukee's M18 battery platform, offering unmatched convenience and mobility for drilling and driving tasks around the home or job site.
With 500 inch-pounds of torque and a no-load speed of 1800 RPM, this drill handles everything from driving screws into hardwood to boring through metal. The 1/2-inch keyless chuck makes bit changes quick and effortless, while the two-speed transmission lets you match speed to the task. Users consistently praise its reliable performance, noting it tackles deck building, kitchen projects, and countless home repairs without faltering.
Design-wise, the drill is compact and lightweight, weighing just over 3 pounds. This makes it easy to maneuver in tight spaces and reduces fatigue during extended use. The brushed motor is a proven workhorse, though it may not be as efficient or long-lasting as a brushless alternative. The overall build quality is solid, typical of Milwaukee tools.
One potential drawback is that this is a tool-only purchase; you'll need to supply your own M18 battery and charger. Additionally, some customers have reported receiving units that appear used or in non-retail packaging, so it's wise to purchase from reputable sellers. A few isolated incidents of sparking upon first use have been noted, but these appear to be rare exceptions rather than the rule.
Overall, the Milwaukee M18 Compact Drill Driver offers excellent value for those already invested in the M18 system or looking to start. Its blend of power, portability, and reliability makes it a solid choice for everyday drilling and driving tasks. With careful purchasing, this drill will serve you well for years.
Pros

- Brushless motor runs cooler and lasts longer than traditional brush motors
- 12-position clutch prevents over-tightening and protects delicate fasteners and surfaces
- Part of extensive M12 ecosystem eliminates need for multiple battery systems
- Highly rated by professionals who use it daily in demanding applications
Cons
- Bare tool only, requires separate purchase of M12 RedLithium batteries and charger
- 3/8 inch chuck limits drilling capacity compared to full-size drill drivers
- Battery compatibility restricted to Milwaukee M12 system, not universal
The Milwaukee M12 Subcompact Brushless 3/8 Drill/Driver is a purpose-built tool for professionals and serious DIYers who work in confined spaces. Whether you're an electrician running conduit, an HVAC technician accessing tight crawlspaces, or a maintenance professional working overhead, this compact powerhouse delivers the performance you need without the bulk of full-size alternatives.
What makes this drill stand out is the combination of brushless motor technology, 12 clutch settings, and 350 in-lb of torque packed into just 1.6 pounds. The brushless motor prevents overloads and overheating, meaning longer runtime and extended tool life. The variable clutch is a game-changer for precision work, allowing you to adjust tightness without stripping fasteners or damaging soft materials. Real users, including auto technicians and construction professionals, consistently praise its surprising power and responsiveness.
Build quality is excellent throughout. The metal keyless chuck provides durability and reliable bit retention, while the overall construction feels solid despite the lightweight design. The 1550 RPM speed is sufficient for both drilling and driving applications, and the tool responds intuitively to variable trigger control. The compact form factor truly makes a difference in tight quarters where standard drills simply won't fit.
The main consideration is that this is a bare tool, so you'll need to invest in M12 RedLithium batteries and a charger if you don't already own them. However, if you're building a Milwaukee tool collection or already use M12 tools, this drill becomes an exceptional value. The compatibility with 150+ other M12 tools means you can build a complete system around a single battery platform.

Buying Guide
Power and Torque
When choosing a Milwaukee cordless drill, consider the torque and speed range. The M18 Fuel models deliver up to 1,200 in./lbs. of torque for driving large fasteners and drilling into masonry, while the M12 compact line offers sufficient power for light framing and furniture assembly. For heavy-duty work, look for a brushless motor and a mechanical clutch to prevent overdriving.
Chuck and Durability
A metal chuck with carbide teeth, like the 1/2-inch all-metal chuck on the M18 Fuel hammer drill, ensures maximum bit retention and longevity. For lighter tasks, a keyless chuck on compact models provides quick bit changes. All Milwaukee drills are built to withstand job site drops and dust, but the Fuel series adds extra protection against overloads.

A well-balanced drill reduces fatigue during extended use. The M18 Compact Brushless drill is only 5.7 inches long and weighs under 3.5 pounds, making it excellent for overhead work. For car interior detailing, a compact drill paired with a portable vacuum can keep your vehicle spotless; check our best car vacuum under $50 for budget-friendly cleanup options.
Final Thoughts
