18V vs 24V Combo Kit Comparison
Number of Tools
The Greenworks 24V kit includes five distinct tools: a drill driver, impact driver, circular saw, multi-tool, and flashlight. This variety covers drilling, fastening, cutting, scraping, and lighting tasks. In contrast, the Metabo HPT 18V kit contains only two tools: an impact driver and a brad nailer. While the Metabo set is focused on fastening, the Greenworks set offers broader utility for general home projects. You get significantly more tool diversity with the 24V option, making it a more comprehensive solution for varied tasks.
Voltage
Voltage represents the electrical pressure available to drive the motors. The Greenworks kit operates at 24V, while the Metabo HPT kit uses 18V. Higher voltage typically allows for greater power output and sustained performance under heavy loads. The 24V system is designed to deliver fade-free power with cooler operation, as noted in the product features. The 18V system relies on MultiVolt technology for efficiency. For users prioritizing raw power potential, the higher voltage of the Greenworks system provides a clear advantage in capability.
Maximum Torque
Torque measures the twisting force the tools can generate. The Greenworks impact driver delivers 1,950 in-lbs of torque, whereas the Metabo HPT impact driver provides 1,549 in-lbs. The Greenworks drill also offers 400 in-lbs of torque. Higher torque allows for driving larger fasteners and drilling through denser materials more effectively. The 24V kit’s impact driver outperforms the 18V model by a significant margin. If your work involves heavy-duty fastening or tough materials, the higher torque specification of the Greenworks tools is a practical benefit.
Battery Capacity
Battery capacity determines runtime between charges, measured in Amp-hours (Ah). The Greenworks kit includes both a 4.0 Ah and a 2.0 Ah battery, totaling 6.0 Ah of storage. The Metabo HPT kit includes a single 2.0 Ah battery. The larger capacity in the Greenworks system supports longer continuous use, especially with power-hungry tools like the circular saw. The 24V batteries also feature USB-C ports for charging devices, adding versatility. For extended workdays without swapping batteries, the higher total capacity of the Greenworks kit is superior.
Weight
Weight affects user fatigue, particularly during overhead or extended use. The Metabo HPT impact driver weighs just 2.0 lbs, and the brad nailer is compact at 4.72 inches long. The Greenworks drill and impact driver combo weighs 4.7 lbs. The Metabo tools are significantly lighter and more compact, reducing strain during detailed finish work or elevated tasks. The Greenworks tools are heavier due to their larger motors and broader functionality. For precision work or prolonged overhead use, the lighter weight of the Metabo HPT tools offers a clear ergonomic advantage.

You get both a 4.0Ah and 2.0Ah battery for uninterrupted work. This collection handles drilling, cutting, scraping, and fastening in one comprehensive package.
Users prioritizing maximum torque output
The Greenworks impact driver delivers 1,950 in-lbs of torque. This exceeds the Metabo HPT impact driver's 1,549 in-lbs rating. The 24V system provides 35% more runtime than standard 20V competitors. You benefit from fade-free power and cooler operation. The higher torque helps with heavy-duty fastening tasks on dense materials.
