Edger Blade 8" AC04215 Edger Steel Serrated Blad 1" Center Hole Compatible with Ryobi Expand-It Edger Attachment, Fits Edgers Models UT50500, UT15518, RY15518, RYEDG11, P2310 and P2300B - 3 Packs

What It Is

This is a steel serrated edger blade (8" diameter, 1" center hole) designed for Ryobi Expand-It edger attachments and several standalone edger models. It trims grass along sidewalks, driveways, and flower beds with a toothed edge that cuts through tough turf.

Fitment & Compatibility

Before buying, verify three things:

• Center hole size: Must be 1" (this blade fits standard Ryobi shafts; not compatible with 7/8" or other sizes).
• Attachment type: Works with Ryobi Expand-It edger attachments (straight shaft) – not for trimmer-based edgers with curved shafts or other brands.
• Exact models: Fits UT50500, UT15518, RY15518, RYEDG11, P2310, and P2300B. If your model isn’t listed, measure the existing blade’s hole diameter and outer diameter (8") to confirm.

This is an aftermarket blade (not OEM Ryobi), but it matches the original specs. Avoid using on edgers with a different arbor size or non-Ryobi universal attachments.

Key Things to Know

• Installation difficulty: Easy – remove the old blade, replace with this one, and tighten the nut. No special tools needed beyond a wrench.
• Serrated vs. smooth: Serrated edges cut through thick grass and roots better than smooth blades but may dull faster on rocky soil.
• Durability: Steel construction holds up for several seasons of regular use, but avoid hitting concrete or stones to prevent chipping.
• 3-pack value: Cheaper per blade than buying singles; good for keeping a spare on hand as backups.

Should You Buy It

If you own a compatible Ryobi edger (listed models or Expand-It attachment) and want a reliable, affordable replacement blade, this 3-pack delivers solid performance for the price. It’s ideal for homeowners who edge regularly and want spares without paying OEM markup. Skip it if your edger uses a different arbor size or you need a smooth blade for fine trimming.
