James T. ★★★★★

Installed this on a 1-1/8 inch bit I use for hinge mortises, and it spins noticeably smoother than the stock bearing it replaced. Fit was exactly right with the 1/2 inch inner diameter. Great to get an exact replacement that keeps a good bit working like new.

John ★★★★★

The 1/2-inch inner diameter fits my bit perfectly, and the bearing spins without a hint of wobble—smooth as glass on a long plunge cut. It’s exactly the replacement I needed to keep that 1-1/8″ bit working like new.

Charlotte ★★★★★

Slapped this on my router bit and it’s spinning way smoother now—the 1/2-inch inner diameter fit perfectly with no wobble. Feels solid for the price.
