DEWALT 20V MAX 12 in. Cordless vs Greenworks 80V 18" Brushless Cordless

Design and Build Quality

The DEWALT 20V MAX focuses on a lightweight design intended to help maximize user control during operation. This makes it suitable for users who prioritize handling ease over raw power. In contrast, the Greenworks 80V model is marketed toward professional users, suggesting a build quality designed for heavier-duty applications. While specific weight measurements are not provided for the Greenworks unit, its classification indicates a robust construction capable of handling demanding tasks. Both units eliminate the need for gas, fumes, and carburetors, offering a cleaner operational profile compared to traditional gas-powered chainsaws.

Cutting Capacity and Bar Length

Cutting capacity is a primary differentiator between these two cordless chainsaws. The DEWALT model comes equipped with a 12-inch low kickback bar and chain. This size is generally appropriate for lighter outdoor cutting applications and construction cuts where precision is key. The Greenworks unit features a significantly larger 18-inch chain and bar. This increased length allows for cutting through larger diameter lumber that the 12-inch bar cannot accommodate. For users dealing with substantial tree limbs or thicker logs, the 18-inch capacity provides a clear functional advantage.

Motor Performance and Power

Both chainsaws utilize brushless motor technology, which typically offers extended motor life and efficient operation compared to brushed alternatives. The Greenworks motor is specified to provide 2X more torque, contributing to its ability to deliver powerful performance comparable to a 42CC gas chainsaw. The DEWALT motor is described as high-efficiency, delivering sufficient power for its intended range of applications. However, the voltage difference is notable, with the Greenworks operating on an 80V system versus the DEWALT 20V MAX system. Higher voltage generally correlates with higher potential power output and the ability to maintain speed under load.

Maintenance and Usability Features

Maintenance features differ significantly between the two models. The Greenworks chainsaw includes an automatic oiler that delivers proper chain lubrication to increase productivity and reduce manual intervention. It also features easy adjust tensioning for straightforward bar and chain maintenance. The DEWALT product data does not specify automatic oiling or tool-free tensioning systems. Users of the DEWALT model may need to perform manual checks and adjustments more frequently. The Greenworks design reduces the complexity of upkeep, which is beneficial for professional users who need to minimize downtime.

Battery Life and Efficiency

Runtime is a critical factor for cordless outdoor power equipment. The DEWALT 20V MAX delivers up to 100 cuts per charge, which supports work long days for lighter tasks. The Greenworks 80V model offers a higher capacity, providing up to 150 cuts on 4x4 lumber on a single charge. This represents a 50% increase in specified cut capacity per charge compared to the DEWALT unit. Both models offer gas-free operation, eliminating cold starts and starter ropes. The efficiency of the brushless motors in both units contributes to their respective runtime capabilities, though the larger battery platform of the Greenworks supports its higher cut count.

Safety and Operation

Safety features are highlighted in the DEWALT product description, which emphasizes a 12-inch low kickback bar and chain to tackle a wide range of applications safely. Low kickback designs reduce the risk of the saw reacting violently during cutting. The Greenworks model mentions push-button start and the elimination of gas-related hazards like fumes and spark plugs. While both units offer the inherent safety benefits of electric operation over gas, the explicit mention of low kickback technology gives the DEWALT a specific edge in stated safety design features for the user during operation.

Price and Value Proposition

The DEWALT 20V MAX is priced at $168.99, making it the more affordable option between the two. The Greenworks 80V model is listed at $246.99, reflecting its higher power output and larger cutting capacity. For buyers on a budget or those who do not require an 18-inch bar, the DEWALT offers a lower entry cost. However, the value of the Greenworks unit lies in its professional-grade specifications, including the automatic oiler and higher voltage platform. Users must weigh the additional cost against the need for the enhanced performance and maintenance features provided by the Greenworks system.

Which One Should You Buy?

Choosing between these two chainsaws depends on the scale of your cutting tasks. If you need to cut larger logs and require longer runtime without recharging, the Greenworks 80V 18-inch model is the superior choice due to its 150-cut capacity and 42CC gas equivalent power. It is better suited for professional users or heavy-duty homeowner tasks. If your needs involve lighter construction cuts, precision work, and you prioritize a lightweight tool with a lower price point, the DEWALT 20V MAX 12-inch model is the appropriate selection. Both eliminate gas maintenance, but the Greenworks offers more advanced maintenance features like automatic oiling.
