What’s Inside the Box? Complete Kit Breakdown

Milwaukee doesn’t skimp on essentials with this package. Here’s everything we found:

– M18 Compact Brushless Drill/Driver (2801-20)
– M18 Compact Brushless Impact Driver (2850-20)
– Two M18 REDLITHIUM 1.5Ah Battery Packs
– Multi-Voltage Charger (compatible with 12V-18V Milwaukee batteries)
– Two belt clips for convenient carrying
– Heavy-duty contractor bag for organized storage and transport

The inclusion of two batteries was particularly appreciated during our testing—we could keep working while one charged, eliminating frustrating downtime that plagues single-battery kits.

Brushless Motor Technology: Why It Matters in Real-World Use

The brushless motor technology in both tools isn’t just marketing hype—we noticed the difference immediately. During extended drilling sessions through hardwood and repeated driving of 3-inch deck screws, these tools stayed noticeably cooler than our older brushed motor counterparts.

The efficiency gains translate to approximately 50% more runtime per charge compared to brushed motors, which we validated during our side-by-side comparison tests. The motors also deliver more consistent power throughout the battery’s discharge cycle, meaning you’re not losing torque as the battery depletes.

Compact Drill/Driver Performance: Small Tool, Big Capabilities

Power Specifications That Deliver

The 2801-20 drill surprised us with its capabilities despite measuring just 6.6 inches in length:

– 500 in-lbs of torque
– Two-speed transmission (0-450 / 0-1,800 RPM)
– 1/2-inch metal ratcheting chuck
– 18+1 clutch settings for precise control

We tested this drill through various materials including 2×10 lumber, metal studs, and even concrete (with appropriate bits), and it handled everything confidently. The compact design proved invaluable when working inside cabinet frames and between studs—spaces where our full-size drill simply wouldn’t fit.

Ergonomics and Comfort During Extended Use

At only 3.6 pounds with the 1.5Ah battery attached, we could work overhead for extended periods without the arm fatigue that typically sets in. The rubberized grip remained comfortable even during all-day use, and the balanced weight distribution minimized wrist strain.

The LED light deserves special mention—it’s positioned perfectly to illuminate your work surface without creating shadows from the drill bit, a small detail that makes a significant difference in dimly lit spaces.

Impact Driver Analysis: The True Workhorse

Driving Power That Impresses

The 2850-20 compact brushless impact driver is where this kit truly shines. With 1,500 in-lbs of torque and 3,200 impacts per minute, we drove hundreds of 3-inch construction screws into framing lumber without a single stall or stripped screw head.

Key specifications include:
– 0-3,000 RPM variable speed
– 1/4-inch hex chuck
– 5.1-inch compact length
– Only 2.5 pounds with battery

Noise Levels and Vibration Control

Impact drivers are notoriously loud, but Milwaukee’s engineering team clearly prioritized user comfort. While still audible, this impact driver operates noticeably quieter than competing models we’ve tested. The vibration dampening is excellent—after driving 200+ screws during deck construction, we experienced none of the hand numbness that plagued us with other brands.

Battery Performance: Real-World Runtime Testing

The two included 1.5Ah REDLITHIUM batteries might seem modest compared to higher capacity options, but they’re perfectly matched to these compact tools. During our testing:

– **Drilling Test**: We drilled 85 1-inch holes through 2×4 framing lumber on a single charge
– **Driving Test**: The impact driver sank approximately 140 3-inch deck screws before requiring a recharge
– **Charge Time**: From depleted to full charge took just 30 minutes

The compact battery size contributes to the tool’s excellent balance and doesn’t add unnecessary weight for most residential and light commercial applications. For heavier usage, the system is fully compatible with Milwaukee’s higher capacity batteries (sold separately).

Multi-Voltage Charger: Versatility for Growing Tool Collections

The included charger handles both 12V and 18V Milwaukee M12 and M18 batteries, which proved incredibly convenient as our tool collection expanded. The sequential charging system automatically prioritizes the first battery inserted, and LED indicators clearly display charging status.

We appreciated that the charger doesn’t generate excessive heat—we could safely leave it on a wooden workbench without concerns, unlike some competitors’ chargers that require heat-resistant surfaces.

Contractor Bag: Durable Storage Solution

The heavy-duty contractor bag exceeded our expectations. Unlike the flimsy canvas bags included with some combo kits, this bag features:

– Reinforced stitching at stress points
– Waterproof bottom panel
– Multiple interior pockets for bits and accessories
– Heavy-duty zipper that operated smoothly even when dusty
– Comfortable carry handles

After months of being tossed in truck beds, dragged through job sites, and exposed to various weather conditions, the bag shows minimal wear and continues protecting the tools effectively.
