AC04215 8" Reversible Heavy Duty Hardened Steel Edger Blade - Compatible with All RYOBI Gas and Cordless Stick edgers, Fits UT50500, UT15518, RY15518, RYEDG11, P2310 and P2300B

What It Is

The AC04215 is an 8-inch, reversible, heavy-duty hardened steel edger blade designed for RYOBI gas and cordless stick edgers. It replaces OEM part #AC04215 and is used for cleanly cutting lawn edges along sidewalks, driveways, and garden beds.

Fitment & Compatibility

Before buying, confirm your edger model. This blade fits RYOBI stick edgers including UT50500, UT15518, RY15518, RYEDG11, P2310, and P2300B. It is an aftermarket replacement for the OEM AC04215 blade. Measure your existing blade diameter: this is exactly 8 inches across, with a 1-inch center hole and three mounting bolts on a 2.5-inch bolt circle. If your edger uses a different hole pattern or diameter, this won’t work. Check your model number on the deck or under the handle.

Key Things to Know

• Reversible design: Flip the blade when one edge dulls, doubling its usable life before sharpening or replacement.
• Hardened steel: More durable than standard steel blades; resists bending on roots and rocks better.
• Installation difficulty: Easy. Remove the old blade with a wrench, align the new blade over the three bolts, and tighten evenly. No special tools needed.
• Common gotcha: Ensure the blade is fully seated flat against the mounting flange before tightening to avoid vibration or wobble.

Should You Buy It

If you own a compatible RYOBI stick edger and want a durable, reversible blade that handles tough edging without constant sharpening, this is a solid value at $7.99. It’s a straightforward upgrade over standard blades, especially for heavy use on hard surfaces or roots. Avoid if your edger uses a different bolt pattern or blade size.
