8 Pcs Metal Lawn Mower Saw Blade Head Replacement Saw Blades Lawn Mower Fittings Cordless with Battery and Charger Accessories,Universal Craftsman String Trimmer attachments

What It Is

This is an 8-pack of metal saw blade heads designed for trimming heavy brush and woody growth, intended as replacement attachments for Craftsman cordless string trimmers that use a battery and charger. The blades are universal-fit for most Craftsman trimmer models.

Fitment & Compatibility

Before buying, confirm your trimmer’s shaft size and attachment mechanism. These blades fit standard Craftsman universal trimmer heads (typically 1-inch diameter shaft with a push-and-twist lock). Not compatible with fixed-head or DeWalt/Ryobi non-Craftsman trimmers. Measure your existing blade’s inner hole diameter and overall length—these are 8-inch diameter blades with a 1-inch arbor hole. Check your model number against Craftsman’s compatibility list (common with 20V and 40V cordless trimmers). Avoid if your trimmer uses a proprietary head (e.g., some older gas models).

Key Things to Know

• Quality vs. OEM: These are aftermarket blades—thinner steel than Craftsman originals; fine for light brush but may dull faster on thick saplings.
• Installation: Tool-free swap if your trimmer has a universal head; just remove the string head and slide on the saw blade. No extra adapters required.
• Safety: Metal blades kick back on dense material—wear eye and leg protection. Not for use near rocks or concrete (blade will chip).
• Common Gotcha: The 8-pack is cheap but each blade lasts 1-2 heavy sessions; you’re buying disposables, not long-term replacements.

Should You Buy It

If you need a budget-friendly way to clear blackberry vines, small branches, or tall weeds with your Craftsman cordless trimmer, this pack works fine. But for regular thick brush or professional use, spend more on a single OEM blade or a dedicated brush cutter attachment.
