2 Pack 9-Inch Heavy-Duty Edger Blades Replacement fits for Ryobi 638006008/638006007 – 1" Center Hole – Hardened Carbon Steel – Fits for Ryobi/Homelite Edger Models

What It Is

This is a 2-pack of 9-inch heavy-duty edger blades designed for Ryobi and Homelite string trimmer attachments and standalone edgers. They’re meant for cutting clean trenches along sidewalks, driveways, and flower beds, not for mowing.

Fitment & Compatibility

Before buying, check three things:

1. Center hole size: Must be exactly 1 inch (these are). Most Ryobi/Homelite edgers use this, but measure yours if unsure.
2. Blade diameter: 9 inches. Confirm your edger’s blade housing or guard accommodates a 9-inch blade (some older models use 8-inch).
3. Model numbers: Fits Ryobi models 638006008 and 638006007 specifically. Also fits many Homelite edgers (e.g., UT41100, UT41102). If your model isn’t listed, measure the existing blade’s hole diameter and overall length.

These are aftermarket replacements, not OEM Ryobi. They work fine for most users, but if you need a warranty-compatible part, stick with OEM.

Key Things to Know

• Material: Hardened carbon steel – sharper out of the box than standard steel, but dulls faster if you hit rocks or gravel. Good for soft soil and grass.
• Installation: Easy – remove the nut, swap blades, re-tighten. Use a torque wrench to 30–40 ft-lbs if possible. Over-tightening can warp the blade.
• Common gotcha: The 1-inch center hole is round, not star-shaped like some OEM Ryobi blades. It will fit, but you may need to reuse the original washer or adapter if your spindle has a non-round shape.
• Pack of 2: You get a spare, which is useful if you frequently edge hard-packed dirt or hit curbs.

Should You Buy It

Buy this if you own a compatible Ryobi or Homelite edger and want a reliable, sharp replacement without paying OEM prices. It’s a solid value for light-to-medium edging jobs. Skip it if you edge rocky soil or need a longer-lasting blade – in that case, look for a carbide-tipped option.
