Worx Nitro 20V 12ft Cordless Brushless Chainsaw - Compact Power

In this review the Worx Nitro 20V 12' cordless brushless chainsaw stands out as a compact, easy-to-use saw best suited for homeowners who need a reliable tool for routine cutting and light felling. The single biggest reason to buy is its brushless motor combined with a 4.0 Ah battery that delivers strong, smooth cuts through branches and small trees without the hassles of gas maintenance. For yard work, storm cleanup and frequent trim jobs this model balances power and portability more effectively than many entry-level cordless saws.

Key Features

• Brushless motor: Provides higher efficiency and more power for cleaner, faster cuts at up to 33 ft/s compared with the prior model.
• 20V Power Share PRO compatibility: Uses a 4.0 Ah battery that extends runtime to handle long sessions and works across other tools in the same battery ecosystem.
• 12' bar and chain: Offers up to 10' cutting capacity that makes bucking and felling small trees and cutting branches straightforward.
• Tool-free chain tensioning: Adjust the chain quickly with the turn of a button for safe, accurate cutting without extra tools.
• Safety kickback stop: The chain stops immediately when kickback occurs, helping reduce the risk of injury during routine tasks.
• Quick bar and chain change: A counterclockwise knob change makes maintenance and replacement fast and simple.

Who It's For

The Worx Nitro is ideal for homeowners, gardeners and DIYers who need a portable saw for yard maintenance, cutting firewood, storm cleanup and small felling tasks. Its size and weight make it especially useful for those who prioritize maneuverability while still wanting a tool that will handle 5 in branches and 10-12 in small trees.

It is less appropriate for professional loggers or heavy commercial use where large diameter trees or long continuous runtimes are required; those users should look for larger battery platforms or gas models that are designed for sustained, heavy cutting.

Pros & Cons

Pros

• Lightweight and easy to handle, making extended cutting sessions less fatiguing.
• Strong cutting speed and efficiency from the brushless motor for fast, smooth cuts.
• Tool-free tensioning and quick bar/chain changes simplify maintenance and keep downtime low.
• Works with the 20V Power Share PRO 4.0 Ah battery for reasonable runtime and cross-compatibility with other tools.

Cons

• Battery life is mixed in reports; some users find a single 4.0 Ah charge limits longer jobs.
• Not intended for heavy commercial felling or very large logs beyond its 10' capacity.
