DWO1DT995 Trimmer Head Compatible with Dewalt DCST920 DCST922 DCST925 DCST970 DCST990 Trimmer Parts, Replacement Head String Spool 0.080" 20Ft (1Pcs)

What It Is

This is a replacement trimmer head and pre-wound string spool (0.080" diameter, 20 feet total) designed for Dewalt DCST-series battery-powered string trimmers. It’s a direct-fit, drop-in part for reloading or replacing a worn-out bump-feed head.

Fitment & Compatibility

• Exact models: Fits Dewalt DCST920, DCST922, DCST925, DCST970, and DCST990.
• Not universal: Does not fit gas-powered Dewalt trimmers or other brands without adapter modifications.
• String size: Uses 0.080" line only—do not force 0.095" or 0.105" line; it will jam or break the head.
• OEM vs aftermarket: This is a non-OEM replacement. It should snap onto the same drive shaft and retain the bump-feed mechanism, but check that the center hole diameter (approx. 0.5") matches your trimmer’s shaft end.
• What to measure: Remove your old head and verify the shaft size (hex or round) and the retaining system (push-button or screw-on). If your original head has a different locking tab pattern, this may wobble.

Key Things to Know

• Installation is simple: No tools needed—just align the head with the shaft, push, and twist to lock. Watch a 2-minute video if you’ve never done it.
• Bump-feed reliability: Some users report occasional feeding hesitation on the first few bumps; it usually works after breaking in the line.
• Line length is limited: 20 feet total (10 feet per side) means more frequent reloads than a head that holds 30+ feet.
• Durability note: The plastic housing is lighter than OEM—fine for light yard work, but may crack if you hit curbs or rocks repeatedly.

Should You Buy It

Buy this if you own one of the listed Dewalt DCST trimmers and need a quick, cheap replacement head that’s pre-wound and ready to go. Skip it if you trim heavy brush or want a heavy-duty head that holds more line—spend a few dollars more for the OEM version or a 0.095" compatible head.
