WORX Cordless String Trimmer 40V 15-inch Nitro WG186 — Brushless Motor, 2x 4.0Ah Batteries

The WORX Nitro WG186 is a 40V cordless 15" string trimmer that delivers gas‑like power with driveshare attachment capability for professional‑grade yard detailing.

The WG186 combines a high‑torque brushless motor, dual‑exit 15" cutting head, and compatibility with WORX DriveShare attachments to handle edging, trimming, and heavy vegetation without gas fumes or frequent maintenance. Included Power Share Pro batteries and a dual‑slot charger provide extended runtime and faster turnaround between jobs, while the split‑shaft design lets you convert the trimmer into multiple tools using sold‑separately driveshare heads.

How powerful is the WG186 compared with gas trimmers?

The Nitro WG186 is engineered to emulate gas performance by pairing a brushless motor with 40V Power Share Pro batteries. It reaches up to 6000 rpm no‑load speed and supports a 0.095" line diameter with a 20 ft. line feed, matching the cutting capacity of many commercial gas models for demanding yards.

• Brushless motor: greater efficiency and longer life than brushed designs
• No‑load speed: 6000 /min for high cutting torque
• Line specs: 0.095" diameter, 20 ft. spool capacity for longer continuous cutting
• Includes two 4.0Ah Power Share Pro batteries for extended runtime

What attachments and conversions can I use with DriveShare?

The WG186 features a split‑shaft DriveShare interface that accepts a range of accessory heads (sold separately), letting one base unit function as a hedge trimmer, pole saw, edger, or brush cutter. This reduces the need for separate gas tools and saves storage space while keeping consistent power and controls across tasks.

• Compatible with WORX DriveShare attachment heads for trimming, edging, and cutting
• Universal fit: designed to work with many other brand attachment systems
• Quick swap: split‑shaft connector for fast tool changes
• Ideal for seasonal or full‑time yard maintenance versatility

How easy is it to use, maintain, and reload line?

WORX designed the WG186 with an easy‑load trimmer head and variable speed control including ECO mode to balance power and battery life. Routine upkeep is minimal compared with gas models: no oil or spark plugs, and brushless motor technology reduces wear, while the included replacement head and simple line loading make upkeep fast.

• Easy‑load trimmer head for quick line replacement
• Variable speed control and ECO mode for runtime management
• No gas, oil, or spark plugs—lower maintenance overall
• Brushless motor reduces friction and extends tool life

Who is this for?

It suits larger or complex yards where longer runtime, durable cutting capacity, and quick conversion to other yard tools are priorities.
