Yes, the WX520L will operate with a 2.0Ah battery but is recommended for best performance to use a 4.0Ah battery.

Yes, the WX520L has a max cutting capacity of 2½ in. at 90° and at 45° the WX520L has a cutting capacity of 1 13/16 in.

A Brushless External Motor provides more efficiency and helps to deliver more power, run time, and durability compared to traditional brushless motors.

The WX520L uses a 7¼ in. blade with a 5/8 in. arbor. We recommend a Thin Kerf blade for best results.

No, the WX520L does not come with a laser cut line.

Although the Power Share™ PRO high-capacity batteries come standard with WORX NITRO products, they can also be utilized on the traditional WORX products to achieve longer runtime.

WORX recommends that Power Share™ PRO batteries be used with WORX NITRO products to unlock optimal performance.

No. The WORX Power Share™ PRO batteries can be used on all existing WORX 20V MAX chargers (WA3742, WA3881, WA3764, WA3770, WA3884, WA3835).

No. The batteries require the same amount of charge-time as the standard WORX Power Share batteries. However, due to the Cell-Cooling Technology in the Power Share™ PRO batteries, they stay cooler, longer. As a result, less wait time is needed before a battery can start charging, due to high temperature.
