Best Dewalt String Trimmer Buying Guide

Best Dewalt Cordless Trimmer

String Trimmer Line Size

A few string trimmers use zip ties, which we don’t recommend, but the vast majority of string trimmers are rated for 0.080 to the 0.105-inch line.

Irrigation pipes and paint on your outside walls are less likely to be damaged by lines with smaller diameters. String trimmers powered by lithium-ion batteries have the longest runtime. As the width of the line increases, it becomes more destructive and less energy efficient, but it also stands up better in tough settings.

Battery-powered string trimmers can handle 0.080-inch lines with ease, allowing you to place more lines on the head than with bigger diameters. Typically, this is the smallest line size we recommend for most situations.

Cutting quickly, minimizing collateral damage, and extending battery life are all advantages of 0.095-inch lines for cordless trimmers. Our recommendation for most cordless trimmers is this thickness, however, some of our Pro models are fine with going up a notch or two.

Professional crews, farms and ranches, and other large sites will benefit from the 0.105-inch line. Unlike other grasses, this one can take a lot of abuse and still get the job done. In order to get the most out of the additional bulk, you’ll likely need a 30cc+ engine. If you’re considering battery-powered options, we only recommend a 0.105-inch line for high-end professional equipment that is specifically designed to handle it.

Cutting Swath

The diameter of your line’s cutting swath is the length of the line. If you’re using a walk-behind mower, you’ll be able to go closer to the landscape edges with a cutting height of 13–14 inches. For professional crews and large property owners, 17 inches or more is ideal, while a 15–16-inch circumference is a good choice for most people.

Weight

The string trimmer’s weight is a significant consideration. Your back needs to work more to support you the heavier you are in the end. Many gas and cordless models come with shoulder straps, which are particularly convenient.

Most of the time, the best string trimmer is the lightest one you can get that yet does the job well enough and is built well enough to last you a long time.

Vibration

Vibration is hard to un-feel. If you’re armed with the right information, though, you can choose a string trimmer that minimizes that movement enough to make a big difference in your comfort and productivity — without sacrificing performance.

Features

For the most part, gas and AC electric string trimmers have the same set of functions. While brushless battery-powered versions have fewer limitations, they can nonetheless affect your purchase decision in a negative manner. Here are a few things to keep an eye out for:

Value

We’re huge on getting the most bang for our buck, therefore getting the most bang for our buck is always a priority for us. It’s not just a question of finding the cheapest string trimmer. It’s all about delivering on your main priorities while staying under budget.
