AMTHKNO 2-Pcs 9 inch Heavy-Duty Edger Blade for Ryobi Edger RY13050 RY13050A RY15518 RY40030 P2300, Replaces 638006008 638006007, 1" Center Hole - Quenched Steel

What It Is

This is a set of two 9-inch heavy-duty edger blades designed for Ryobi gas edgers. They cut a clean edge along driveways, sidewalks, and garden beds, replacing OEM parts 638006008 and 638006007.

Fitment & Compatibility

Before buying, confirm your edger model is on this list: Ryobi RY13050, RY13050A, RY15518, RY40030, or P2300. The blade has a 1-inch center hole and a 9-inch diameter—measure your current blade’s hole size and diameter to verify. These are aftermarket replacements, not OEM Ryobi, but they match the original specs exactly. Do not use on edgers with a smaller or larger arbor hole (e.g., 7/8-inch or 1-1/4-inch).

Key Things to Know

• Material: Quenched steel is harder than standard steel, so the blade stays sharp longer but is more brittle if you hit rocks or curbs—check for chips after each use.
• Installation: Easy swap with a single bolt; use a wrench to tighten firmly but don’t overtighten. No special tools needed.
• Gotcha: The blade is directional—ensure the stamped arrow or cutting edge faces the correct rotation direction (counterclockwise on most Ryobi edgers).
• Pair value: Two blades for $9.99 means you have a spare or can replace both ends on dual-blade models (check your edger—most use one at a time).

Should You Buy It

Buy this if you own a compatible Ryobi edger and want a durable, cost-effective replacement that matches OEM performance. Avoid if you need a blade for a different brand or a non-compatible Ryobi model—double-check your model number and center hole size first.
