KitchenKipper 2-Pack AC04215 8" Edger Blade (1" Center Hole) Compatible with Ryobi 818-928 Expand-It Edger Attachment, Fits Models UT50500, UT15518, RY15518 Heavy Duty Edger

What It Is

This is a two-pack of 8-inch edger blades designed for Ryobi Expand-It edger attachments. Each blade has a 1-inch center hole and is meant to replace worn or dull blades on Ryobi models UT50500, UT15518, and RY15518.

Fitment & Compatibility

Before buying, confirm your Ryobi Expand-It attachment model number (stamped on the shaft or user manual). This blade fits the 818-928 edger attachment and the three listed Ryobi models. The 1-inch center hole is standard for most Ryobi Expand-It edgers, but measure your existing blade’s hole diameter and overall blade length (8 inches) to be sure. This is an aftermarket part, not OEM Ryobi, so check that the blade thickness and mounting hole match your unit—some older attachments may have slight variations.

Key Things to Know

• Installation is easy: Remove the old blade, slide the new one onto the shaft, and tighten the retaining nut. No special tools needed beyond a wrench.
• Heavy-duty build: These blades are thicker than standard edger blades, so they last longer on tough turf and roots, but they may add a bit more vibration at high RPM.
• Two-pack value: You get two blades for the price of one OEM Ryobi blade—good for replacing both ends of a dual-blade setup or keeping a spare.
• No universal fit: Only compatible with the specific Ryobi models listed. Will not fit other brands or older Ryobi attachments with different shaft diameters.

Should You Buy It

If you own a Ryobi Expand-It edger (UT50500, UT15518, or RY15518) and want a durable, budget-friendly replacement, this two-pack is a solid choice. It’s easy to install, lasts well on heavy use, and saves money over OEM options. Skip it if you need a blade for a different brand or an older Ryobi model with a non-standard center hole.
