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. (6.35 cm) at 90° and at 45° the WX520L has a cutting capacity of 1 13/16 in. (4.60 cm)

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. (18.41 cm) blade with a 5/8 in. (1.58 cm) arbor. We recommend a Thin Kerf blade for best results.

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

Although the WORX 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 POWERSHARE batteries. However, due to the Cell-Cooling Technology in the POWERSHARE PRO batteries, they stay cooler, longer. As a result, less wait-time is needed before a battery can start charging, due to high temperature.
