Buying Guide for Replacement Heads for Dewalt String Trimmers
Compatibility
Check your Dewalt string trimmer model number carefully before purchase. Most replacement heads specify compatible models such as DCST920, DCST922, DCST970, and others. Using a mismatched head can cause functional issues or damage.
Loading Mechanism
Replacement heads come with various loading types including QuickLoad, bump feed, and pre-wound spool systems. QuickLoad heads allow fast line replacement with fewer steps, while bump feed heads advance the line after tapping the trimmer on the ground. Pre-wound spools make initial loading easier but may require replacement spools over time.
Line Diameter and Length
Standard line diameters compatible with Dewalt trimmer heads include 0.080″ and 0.095″. Thicker lines provide more cutting power but may require appropriate power from the trimmer. Look for heads that support both diameters if you want flexibility. Line length impacts how long you can trim before reloading.
Material and Durability
Most replacement heads use ABS plastic or nylon for outer shells and trimmer line. ABS plastic offers impact resistance and longevity, suitable for heavy use. Nylon lines are durable yet flexible for effective trimming. Ensure the materials are high-quality to maximize service life.
Included Parts
Some replacement kits include additional components like springs and caps, required for maintaining optimal head function. If purchasing only the spool or cap separately, ensure compatibility with your existing setup or consider full kit replacements for convenience.
Genuine OEM vs. Aftermarket
OEM parts guarantee perfect fit and factory-tested quality. Aftermarket products can offer cost savings and equivalent performance but verify reviews and specifications to ensure compatibility and quality for your Dewalt trimmer.
