Overview
This replacement edger blade pack (AC04215) is built from hardened steel and engineered as a direct swap for the factory blade on Ryobi stick edgers and Expand-It edger attachments. Edger blades wear down, chip, and lose their edge after repeated contact with concrete and asphalt, so keeping spare blades on hand means you can maintain crisp lawn borders without waiting for a parts order. This aftermarket set delivers OEM-equivalent fit and cutting depth at a lower price point.

Compatibility
Fits Ryobi Expand-It edger attachments (RYEDG12, RYEDG12VNM, RY15518, UT15518, RYEDG11, UT50500), Ryobi 18V ONE+ edgers (P2300, P2310, P2312), Ryobi 40V HP brushless stick edgers (RY40706, RY40760, RY40780), and Trimmer Plus LE720/LE720r Expand-It edger attachments. Confirm your edger uses an 8-inch blade with a 1-inch center hole before purchasing.
Installation notes
Disconnect the battery or power source and wait for the blade to stop completely. Remove the blade retaining bolt and flat washer, then slide the worn blade off the arbor shaft. Position the new blade with the stamped markings facing outward and reinstall the washer and bolt, tightening to the torque specified in your edger’s manual. After reassembly, rotate the blade by hand to make sure it clears the blade guard with no interference.
Common questions
Q: Will this AC04215 8-inch blade fit my Ryobi RY40780VNM 40V HP Brushless stick edger and my older RYEDG12 Expand-It attachment?
Yes, this replacement blade is made for the Ryobi models listed, including the RY40780VNM and the RYEDG12/RYEDG12VNM Expand-It edgers. As long as your unit uses the AC04215-style 8-inch blade shown in the listing, it should install correctly in place of the original.
Q: How do I install this blade on a Ryobi P2312 18V ONE+ edger, and do I need to watch blade direction?
Remove the battery first, then take off the blade retaining hardware and swap the old blade for the new 8-inch blade in the same orientation. Make sure the blade seats fully on the arbor, reinstall the washer/nut securely, and check that any directional markings match the rotation of the edger before use.
Q: How often should I replace or inspect this blade on a Ryobi RY40760 or P2310, and what signs mean it’s worn out?
Inspect the blade regularly for rounded cutting edges, bending, cracks, or heavy nicks from hitting concrete, roots, or rocks. If edging starts taking more passes than usual or the tool begins to vibrate more, it’s a good sign the blade should be replaced rather than continued in service.
