2 Pack 638006008 Heavy Duty 9 inch Edger Blade/w Teeth 1" Center Hole Replacement Sharpen Edging Blades for Ryobi RY13050 P2300A P2310 RY13050A RY15518 RY40030 Trimmer Edger

What It Is

This is a 2-pack of heavy-duty 9-inch edger blades with teeth, designed to replace worn blades on Ryobi straight-shaft trimmer/edger combos and dedicated edgers. The 1-inch center hole and toothed edge cut through turf and compacted soil for clean lawn edges.

Fitment & Compatibility

• Center hole: Must be exactly 1 inch (25.4mm) – measure your current blade’s center hole before ordering. This fits Ryobi models like RY13050, P2300A, P2310, RY13050A, RY15518, and RY40030.
• Blade diameter: 9 inches – confirm your edger’s blade guard accommodates a 9-inch blade (some older models use 7 or 8 inch).
• Shaft type: Straight-shaft only. Curved-shaft Ryobi trimmers (e.g., RY13002) use a different blade with a smaller hole.
• OEM vs aftermarket: This is a third-party blade, not genuine Ryobi. It’s a direct fit for listed models but may vary slightly in thickness or balance. Check your owner’s manual for exact OEM part number (Ryobi 638006008 is the equivalent).

Key Things to Buy

• Quality: Heavy-duty steel with teeth – holds an edge longer than standard blades but will dull faster if you hit rocks or concrete. Teeth can be sharpened with a file.
• Installation: Easy – remove the nut, swap blades, re-tighten. Use thread locker if the nut loosens during use. No special tools needed beyond a wrench.
• Common gotchas: The blade may wobble if the center hole is slightly oversized (rare). Always tighten to manufacturer torque specs (typically 15-20 ft-lbs). Wear gloves – teeth are sharp out of the box.
• Durability: The 2-pack gives you a spare; expect 20-30 hours of edging per blade on normal turf. Replace sooner if you see cracks or bent teeth.

Should You Buy It

If you own a compatible Ryobi straight-shaft edger and want a cost-effective replacement that works as well as the OEM blade, this 2-pack is a solid value. Avoid it if you need a curved-shaft blade or a non-toothed design for lighter trimming.
