DeWalt 60V MAX FLEXVOLT String Trimmer DCST972B (bare tool; the DCST972X1 kit has been discontinued): What to Know
The draft candidate for this slot was the DEWALT FLEXVOLT DCST972X1, a kit bundling this trimmer with a 3.0Ah battery and charger. We confirmed directly on DEWALT's own product page that the DCST972X1 kit specifically now carries a 'Discontinued' label. The underlying trimmer platform is still current, though: DEWALT's DCST972B, the bare-tool version of the same 60V MAX FLEXVOLT trimmer, is not marked discontinued and has a live, in-stock Amazon listing (ASIN B08QVCLS3G). We're recommending that bare-tool listing, with the important caveat that it does not include a battery or charger.
The DCST972B runs on DEWALT's 60V MAX FLEXVOLT battery system, and is also backward-compatible with DEWALT's 20V MAX batteries at reduced power, which matters if you're already invested in DEWALT's broader jobsite tool lineup. Cutting swath adjusts between 15 and 17 inches using 0.080-inch dual line, and DEWALT states it's also compatible with thicker 0.095-inch line. Line reloading uses a Quick-Load spool design.
What sets this trimmer apart from the others in this guide is DEWALT's Universal Attachment capability: the power head is designed to accept additional DEWALT attachment tool heads beyond just the trimmer string head, which none of the other four trimmers here offer. That flexibility is a real reason to choose this platform if you're building out a multi-tool cordless yard setup rather than buying single-purpose tools.
On weight, sources disagree more than we'd like: some retailer spec sheets list the bare tool around 9.6 lbs, others around 10.3 lbs, with a fully-batteried weight (using a large 9.0Ah battery) reaching roughly 13.5 lbs. We're presenting that range honestly rather than picking whichever number looked best. Because this is a bare tool, budget for a separate 60V MAX FLEXVOLT battery and charger purchase, DEWALT and third-party retailers sell these separately, which can add a meaningful amount to the total cost versus a bundled kit like the RYOBI or Greenworks options above.
