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-piece set of metal saw blade heads designed for use with cordless string trimmers and brush cutters, intended for heavy-duty vegetation clearing (e.g., thick weeds, brush, small saplings). It includes blades, a battery, and charger—not a standalone mower blade replacement for a standard lawn mower deck.

Fitment & Compatibility

• Not for push mowers or riding mowers – these are trimmer/brush cutter attachments, not lawn mower blades. Do not install on a mower deck.
• Check your trimmer’s shaft type – most Craftsman cordless trimmers use a straight shaft with a universal mounting hole pattern (typically 1-inch diameter center hole with 4- or 6-point star pattern). Measure your trimmer head’s mounting hole diameter and pattern before buying.
• Battery/charger compatibility – the included battery and charger are likely for the blades’ own power system, not for your existing Craftsman tools. Verify voltage (e.g., 20V/40V) matches your existing Craftsman battery platform if you plan to swap.
• OEM vs aftermarket – this is an aftermarket kit; not a genuine Craftsman part. It may fit but tolerances vary.

Key Things to Know

• Installation difficulty – easy if you have a wrench and can remove the trimmer’s existing head; no special tools required.
• Quality – metal blades are more durable than nylon line for heavy brush but dull faster on rocky soil. The included battery/charger may be lower capacity than your original.
• Common gotcha – these blades are designed for brush cutting, not grass trimming. Using them on grass can scalp or damage turf. Also, metal blades require a trimmer with a metal blade-compatible guard (often sold separately).
• Safety – always wear eye and leg protection; metal blades can throw debris at higher force than nylon line.

Should You Buy It

Buy this if you need a low-cost, multi-blade set for occasional heavy brush clearing with a compatible Craftsman cordless trimmer and don’t mind an aftermarket battery/charger. Skip it if you need genuine OEM parts, have a gas trimmer, or primarily cut grass—nylon line is better for that.
