DEWALT DCST920B MAX XR Review – 20V Lithium Ion Brushless String Trimmer


DEWALT DCST920B is a cordless battery powered string trimmer. It has brushless motor with 2 speed settings: 4,600 & 6,000 RPM. It uses 0.080” line and has cutting swath of 13 inches.

Cutting performance is good. It’s not quite as powerful as gas string trimmers but it’s not far off. Even on lower speed setting most of the time it cuts thick stuff without problems. DEWALT DCST920B can handle nearly everything you throw at it.

DEWALT DCST920B is usually sold without batteries so battery life heavily varies depending on how you use it and what kind batteries you have.

It must be noted that by now DEWALT DCST920B is considered an old model by now and has been succeeded by DCST922B.


Ergonomics

This is where DEWALT DCST920B MAX XR 20V string trimmer fails. It’s not comfortable to use.

First of all it’s rather heavy: it weighs 7.3 lbs without batteries and 8.5 lbs with 20V MAX* 5.0Ah battery (DCB205) – less than most gas string trimmers but more than battery powered ones. But the weight isn’t main issue.

Trimming head cannot be adjusted and is quite heavy ruining the balance – to keep trimmer flat you have to hold it in a weird way that’s uncomfortable.

Lower handle is fixed too and cannot be adjusted as well – the way it sits just feels wrong.

Guard is very small in size rendering in pretty much useless as you will be constantly be hit with stuff.


Conclusions


DEWALT DCST920B is a disappointing string trimmer and just feels like missed chance. It performs very well but unfortunately isn’t thoughtfully designed resulting in multiple flaws.

  • Good
    • Powerful
  • Bad
    • Heavy’ish
    • Uncomfortable to use
    • Guard doesn’t protect you properly
