Cordless Grass Trimmer Blades: Heads, Line and Fit

Check whether your cordless trimmer uses a blade, fixed-line head, or a conventional line spool before ordering parts.

Cordless grass trimmer blades can refer to replaceable plastic blades or a blade-capable head, but many cordless string trimmers use nylon line instead. Check the exact tool model and cutting-head type before buying a replacement; parts that look similar may not fit or be approved for your machine.

Common questions

Questions before you buy

Do cordless grass trimmers use blades or string?

It depends on the model and head. Many string trimmers use nylon line; some compatible heads use designated blades. Check the manual before changing the cutting attachment.

Can I put a blade on any cordless string trimmer?

No. Use only attachments approved for the exact model. An incompatible head can create safety and fit problems.

How do I choose replacement blades for a cordless strimmer?

Use the product model and the manufacturer’s parts list to identify the specified replacement blade or head. Confirm the fitting instructions and safety requirements.

Are fixed-line heads the same as blades?

No. Fixed-line heads hold short pieces of trimmer line; blades are separate cutting parts designed for compatible heads and tools.
