TPCABPART 2-in-1 Pivoting Trimmer Head for 18V–40V Strimmers – Fixed Line & Serrated Blade, Tool-Free Quick-Change

Two cutting modes in one durable trimmer head — use fixed nylon line for regular trimming or a serrated blade for heavy weeds, all on a quick‑change, pivoting mount.

This replacement trimmer head from TPCABPART is built for cordless auto‑feed string trimmers across 18V, hybrid, 24V and many 40V models. It installs without tools and locks into compatible stringer sockets using integrated side push buttons. The package includes one trimmer head and six replacement serrated blades so you can swap cutting styles depending on the job.

How does this 2‑in‑1 head switch between fixed line and blade modes?

Changing cutting modes is designed to be quick and tool‑free. The head accepts either a fixed nylon cutting line or a serrated blade and uses a simple twist/lock or push release to secure the chosen cutting element. Switching back is equally straightforward so you can adapt to dense weeds or routine trimming without downtime.

• Tool‑free change mechanism for fast swaps
• Pivoting mount allows angled cutting where needed
• Includes six replacement serrated blades
• Secure lock via side push buttons for reliable engagement

Will this trimmer head fit my trimmer model?

The head is compatible with a long list of automatic feed trimmer models (see product listing). It fits many 18V, hybrid, 24V and 40V machines that use the same quick‑attach socket. Note: it is not compatible with RYOBI 40V EXPAND‑IT systems.

• Fits numerous P‑series models like P2080, P2008, P20100 and others
• Works with RY40210 and RY40210A series mounts
• Not compatible with RYOBI 40V EXPAND‑IT platforms
• Check your trimmer’s quick‑attach socket type before purchase

How does the serrated blade perform and when should I use it?

The serrated blade is intended for tackling thick weeds, tall grass and tough vegetation that would bog down a nylon line. Because the blade is rigid and aggressive, avoid edging or making contact with fences, concrete or metal surfaces to prevent damage. Use the blade for heavier overgrowth and switch to fixed line for precision trimming near borders.

• Serrated blades cut through dense, fibrous growth effectively
• Avoid contact with hard surfaces to preserve blade life
• Fixed nylon line offers safer edging and finer control
• Quick change makes alternating between tasks simple

How easy is installation and maintenance?

Installation is designed to be straightforward: push the head into the trimmer’s socket until the side buttons click and lock it in place. Routine maintenance involves keeping blades sharp and replacing worn nylon line when needed. The included replacement blades simplify upkeep so you can swap parts without hunting for extras.

• Push‑in installation with side‑button locking — no adapter required
• Keep blades clean and replace when dull for best performance
• Store spare blades dry to prevent corrosion
• Replace nylon line as it wears for consistent cutting

Who is this for: This 2‑in‑1 trimmer head suits homeowners and landscaping pros who need a versatile, fast‑changing cutting solution for cordless auto‑feed trimmers. It’s ideal if you regularly move between light precision trimming and heavier brush clearing and want a compact head that fits many 18V, hybrid, 24V and 40V eligible models. Confirm model compatibility before purchase and avoid using it on RYOBI 40V EXPAND‑IT systems.
