DEWALT 20V MAX 9-Tool Combo Kit (DCK940D2): The Ultimate Power Tool Arsenal for Pros & DIYers

After spending three weeks putting the DEWALT 20V MAX 9-Tool Combo Kit through its paces on various projects, I can confidently say this comprehensive power tool set delivers exceptional performance and versatility that both professionals and serious DIY enthusiasts will appreciate. Let me walk you through everything you need to know about this impressive toolkit.

What’s Included in This Professional-Grade Power Tool Set

The DEWALT DCK940D2 comes loaded with nine essential power tools that form the backbone of any serious workshop or jobsite setup:

• DCD771 1/2″ Drill/Driver
• DCF885 1/4″ Impact Driver
• DCS393 6-1/2″ Circular Saw
• DCS355 Oscillating Multi-Tool
• DCG412 4-1/2″ Angle Grinder
• DCS381 Reciprocating Saw
• DCL040 LED Work Light
• DCR006 Bluetooth Speaker
• DCS551 Drywall Cut-Out Tool

The kit also includes two 20V MAX 2.0Ah lithium-ion batteries, a charger, and a durable contractor bag to keep everything organized and protected.

Hands-On Performance: Our Real-World Testing Results

During our three-week testing period, we used this combo kit for everything from building a backyard deck to renovating a bathroom and constructing custom shelving. Here’s how these tools performed in real-world applications:

Drill/Driver & Impact Driver: Power Meets Precision

The DCD771 drill/driver handled drilling through hardwoods, pressure-treated lumber, and even concrete blocks (with the right bits) without bogging down. Its two-speed transmission (0-450/0-1,500 RPM) provided excellent control for both delicate work and heavy-duty applications.

The DCF885 impact driver quickly became my go-to for driving screws. With 1,400 in-lbs of torque, it effortlessly sank 3-inch deck screws into dense lumber, while the three LED lights illuminated work areas perfectly, eliminating shadows even in tight corners.

Cutting Tools: Impressive Precision and Power

The DCS393 circular saw cut through 2x4s and plywood with impressive accuracy. Its lightweight design (7.5 lbs) reduced fatigue during overhead cutting, while the 6-1/2″ carbide-tipped blade made quick work of various materials.

The reciprocating saw proved particularly valuable during demolition work, easily cutting through nails embedded in wood and slicing through metal pipes with minimal vibration. The adjustable shoe extended blade life by allowing us to utilize unworn portions of the blade.

The drywall cut-out tool was a pleasant surprise, making precise outlet and fixture cutouts simple and dust-free compared to traditional methods.

Specialty Tools: Versatility for Any Project

The oscillating multi-tool demonstrated exceptional versatility. We used it for undercutting door jambs, making plunge cuts in drywall, sanding in tight corners, and even removing old grout. The quick-change accessory system made switching between applications effortless.

The angle grinder provided plenty of power for cutting metal and masonry materials. The tool-free guard adjustment was particularly helpful when switching between cutting and grinding applications.

Jobsite Conveniences: Beyond the Basics

The LED work light proved invaluable when working in poorly lit areas, with three brightness settings and a pivoting head that allowed us to direct light exactly where needed.

The Bluetooth speaker delivered surprisingly good sound quality and impressive volume, making the workday more enjoyable. Its ability to connect to smartphones up to 100 feet away meant we could keep our devices safely away from dust and debris.

Battery Performance and Runtime That Won’t Let You Down

Throughout our testing, the two included 2.0Ah batteries provided reliable power for most applications. We could complete most standard tasks on a single charge, though for power-hungry tools like the circular saw and reciprocating saw, we found ourselves switching batteries for extended use.

The charger replenished depleted batteries in about 60 minutes, minimizing downtime. For professional users or those tackling larger projects, I’d recommend investing in additional batteries, particularly higher-capacity 4.0Ah or 5.0Ah options for extended runtime with the more demanding tools.

Build Quality: Engineered to Withstand Jobsite Abuse

DEWALT’s reputation for durability was evident throughout this kit. Each tool features robust housing with reinforced impact points and comfortable, ergonomic grips designed to reduce fatigue during extended use.

During our testing, these tools survived multiple accidental drops onto concrete floors and exposure to dust and debris without any performance issues. The contractor bag, while spacious enough to hold all tools, could benefit from additional internal dividers for better organization.

Discover Why This 9-Tool Kit Could Be Your Perfect Workshop Solution

What impressed me most about this kit is the thoughtful selection of tools that cover virtually every common construction and renovation task. Rather than including rarely-used specialty tools, DEWALT has assembled a comprehensive collection of genuinely useful implements that complement each other perfectly.

The cordless design and common battery platform eliminate the frustration of tangled cords and the need for nearby outlets, allowing complete mobility around the jobsite. The consistent ergonomics across the entire line means once you’re comfortable with one tool, the learning curve for others is minimal.
