Eyoloty AF-100 Replacement Trimmer Head Kit — 2-Pack 21‑Piece Polycarbonate Blades for Black & Decker, Aggressive Cutting

Eyoloty AF-100 replacement head assembly with 12 polycarbonate blades and mounting hardware gives your compatible Black+Decker string trimmer a fast, durable cutting option for thicker grass and light brush.

When your line-only trimmer struggles with coarse patches, the Eyoloty 21-piece kit converts compatible Black+Decker models into a tougher cutter using a dual-head design and serrated polycarbonate blades. This set replaces worn heads and supplies multiple blades, screws and a wrench so you can get back to landscaping without waiting for parts. It’s engineered for centrifugal balance and abrasion resistance so the head spins cleanly while delivering more aggressive cuts where monofilament line slows down.

Which trimmer models work with this Eyoloty AF-100 kit?

This replacement head and blades are designed to fit a wide range of Black+Decker electric and cordless trimmers that accept AF-100 style attachments. Confirm compatibility by matching your trimmer model number to the list below or by measuring the existing head mounting style on your tool.

• Compatible models include GH912, GH900, GH600, GH500, GH400 and many LST, NST, MTE and CST series trimmers.
• Fits both corded and battery Black+Decker units that use AF-100 style head fittings.
• Check your owner’s manual or existing head for AF-100 designation before purchase.

How do I install the replacement head and blades?

Installation is straightforward: remove the old head, align the new head with the trimmer’s drive shaft, secure it with the provided screws and attach the dual blades into the head slots. The kit includes a small wrench to help tighten the screws, and the head’s design minimizes tricky maneuvers during assembly.

• Use the included wrench and screws for a secure mount.
• Insert blades into the head so serrated edges face outward for cutting.
• Tighten screws evenly and test spin with the trimmer off the ground before operation.

What cutting performance can I expect from the polycarbonate blades?

The twelve polycarbonate blades have serrated edges that provide sharper, more aggressive cutting than string alone on tough vegetation. Their material balances flexibility and toughness to resist chipping while using centrifugal force to maintain clean cutting angles at high RPMs.

• Serrated edges handle thicker grass and light brush more effectively than line.
• Polycarbonate construction offers abrasion resistance for repeated use.
• Dual-blade head uses aerodynamics to reduce resistance and improve cut speed.

What does the 21-piece kit include, and how long will parts last?

The package bundles two preassembled polycarbonate heads, twelve replacement blades, six mounting screws and one installation wrench so you have spares for multiple sessions. Longevity depends on material contact and workload—reserve serrated blades for heavier patches and switch to line for everyday edging to extend blade life.

• Includes: 2 AF-100 heads, 12 polycarbonate blades, 6 screws, 1 wrench.
• Expect longer service life when avoiding hard surfaces and reducing blade contact with stones or concrete.
• Keep spare blades on hand to swap when serrations dull from frequent thick-brush work.

Who is this for: Landscapers and homeowners with compatible Black+Decker trimmers who need a stronger cutting option for dense grass, weeds or light brush. If you want a fast replacement head with spare blades and hardware included—so you can minimize downtime and handle tougher trimming tasks—this Eyoloty AF-100 kit offers an economical way to upgrade your trimmer’s capability without buying a new tool.
