DWO1DT995 Weed Trimmer Head Replacement for Dewalt DCST922 DCST925 DCST970 DCST920 DCST991 DCST990 String Trimmer, Weed Eater Head Parts Weed Wacker Head with 0.080" Spool Line

What It Is

This is an aftermarket replacement trimmer head designed for Dewalt DCST-series battery string trimmers. It uses a bump-feed mechanism and comes pre-wound with 0.080-inch spool line, intended for residential trimming of grass and light weeds.

Fitment & Compatibility

Before buying, confirm your trimmer model matches one of these: DCST922, DCST925, DCST970, DCST920, DCST991, or DCST990. This head is not OEM Dewalt; it’s a third-party replacement. Measure the existing head’s diameter (typically 10–11 inches) and the shaft diameter (most Dewalt DCST models use a 25mm or 1-inch shaft). Check that the bump-feed button aligns with your trimmer’s guard. If your model uses a different mounting system (e.g., quick-load or fixed-head), this won’t fit.

Key Things to Know

• Installation: Tool-free—screws onto the threaded shaft. No adapters needed for listed models, but ensure the shaft is clean and free of debris.
• Line quality: The included 0.080-inch line is standard for light duty. For thicker weeds, upgrade to a heavier line (0.095-inch max) if the head’s spool allows.
• Durability: Some users report the bump-feed mechanism can jam if the head is impacted against hard surfaces. Avoid hitting curbs or rocks.
• Spool refill: The head uses a pre-wound spool; replacing it is easier than hand-winding, but check that replacement spools are widely available and compatible.

Should You Buy It

If you own one of the listed Dewalt DCST trimmers and need a budget-friendly, easy-to-install replacement head for routine grass trimming, this is a solid choice. It’s not built for heavy commercial use or thick brush, but for occasional residential yard work at under $12, it offers good value. Skip it if you have a non-DCST model or need a heavy-duty head for dense weeds.
