20V vs 24V Kit Comparison
Voltage and Power
The DEWALT kit operates at 20V MAX, while the Greenworks model uses 24V. Greenworks claims its 24V brushless motor delivers two times more torque and thirty-five percent longer runtime compared to 20V competitors. It also states the lithium-ion battery provides twenty percent more power and thirty-five percent more run-time than a standard 20V battery. This higher voltage system is designed to offer fade-free power and cooler operation during extended use. You get consistent performance without memory loss after charging, which supports heavy-duty tasks that demand sustained energy output.
Number of Tools
You need to consider how many tools fit your workflow. The DEWALT combo includes just two core tools: a drill/driver and an impact driver. The Greenworks kit is a five-tool combination that adds significant versatility. Beyond the drill and impact driver, it includes a circular saw, a multi-tool, and a work light. This broader selection allows you to handle cutting, scraping, and sanding without buying separate kits. If you want a single purchase that covers more ground, the five-tool set offers more utility for diverse projects around the home or job site.
Motor Type
Motor technology affects efficiency and longevity. The Greenworks kit features brushless motors in its drill, impact driver, and circular saw. Brushless designs generally provide cooler operation, extended tool life, and better power management. The DEWALT listing does not specify brushless motors for its included tools, focusing instead on compact design and ergonomic features. Brushless motors typically reduce maintenance needs and improve runtime. For users prioritizing modern motor efficiency and durability, the Greenworks specification offers a clear technical advantage over the standard brushed motor assumption in many basic kits.
Battery Capacity
Battery specifications determine how long you can work before recharging. The Greenworks kit includes a 4.0 Ah battery and a 2.0 Ah battery. The DEWALT kit includes two batteries, but the specific amp-hour capacity is not listed in the provided data. Greenworks highlights that its batteries are designed for fade-free power and include a USB-C port for charging devices. The 4.0 Ah capacity suggests longer runtime for demanding tasks. Without the exact Ah rating for the DEWALT batteries, it is difficult to compare endurance directly, though Greenworks explicitly quantifies its capacity for your planning.
Chuck Size
Both kits feature compatible chucks for standard bits. The DEWALT drill has a 1/2 inch single sleeve ratcheting chuck, and its impact driver uses a 1/4 inch hex chuck. The Greenworks drill also features a 1/2 inch chuck, and its impact driver uses a 1/4 inch hex chuck. This means you can use the same drill bits and driver bits in either kit. There is no functional difference in chuck compatibility between the two options. Both systems support standard 1/4 inch bit tips and 1/2 inch drill chucks, ensuring you can swap accessories freely between these platforms.
Which 20V or 24V Kit Fits You
Users needing just drill and impact driver
This DEWALT kit includes only a drill and impact driver. It is compact and lightweight, weighing 3.6 pounds for the drill. The design fits into tight spaces. You get two batteries and a bag for storage. This option is ideal if you do not need extra tools like a saw or multi-tool. It keeps your load minimal.
DIYers wanting five tools in one kit
This Greenworks kit provides five tools: a drill, impact driver, circular saw, multi-tool, and flashlight. You get higher voltage and brushless motors for more torque and runtime. The circular saw cuts wood and metal with a carbide-tipped blade. The multi-tool offers 18,000 OPM for sanding and scraping. This bundle covers more project types than a two-tool set.
Professionals needing circular saw and multi-tool
You get a circular saw with 4,800 RPM and a multi-tool with 18,000 OPM. These tools are not included in the two-tool 20V kit. The brushless motors provide fade-free power and longer life. You also receive a 4.0 Ah and a 2.0 Ah battery. This kit is better for jobs requiring cutting and detailed finishing work alongside drilling.

Frequently asked questions
Is 24V significantly more powerful than 20V?
Yes, 24V systems generally deliver higher torque and runtime. The Greenworks 24V model uses brushless motors to provide two times more torque than standard 20V competitors. It also offers thirty-five percent longer runtime for demanding tasks. This makes 24V better for heavy-duty work where raw power matters most.
Which kit is better for tight spaces?
The 20V DEWALT kit is better for tight spaces. It weighs only 3.6 pounds for the drill driver. Its compact design fits into narrow areas where bulkier tools cannot reach. If you prioritize portability and maneuverability over raw power, the lighter 20V option is the practical choice.
How many tools are in each kit?
The number of tools varies by model. The DEWALT 20V kit includes a drill driver and an impact driver. The Greenworks 24V kit contains five tools: a drill driver, impact driver, circular saw, work light, and oscillating tool. Choose based on whether you need just core tools or a full set.
Do 24V batteries last longer than 20V?
The Greenworks 24V kit claims thirty-five percent longer runtime. It includes 4.0 Ah and 2.0 Ah batteries to support extended use. While 20V batteries are common, the 24V system is designed for tasks requiring sustained power. Check the amp-hour rating to understand specific battery endurance for your projects.
Is the 24V kit heavier than the 20V?
Yes, the 24V kit is significantly heavier. The Greenworks 24V 5-Tool Combo Kit weighs 21 pounds total. In contrast, the DEWALT 20V drill driver weighs just 3.6 pounds. The weight difference comes from the additional tools and larger batteries included in the 24V package.
