Premium CNC & Router Bits for Precision Cutting

1/2″ Square Ball Bearing x 3/16″ID – Whiteside B3SQ

If residue build-up on the bearing or marring of the workpiece is a problem, the Euro Square Bearing replaces the standard 1/2″ bearing found on most of Whiteside’s Edge Form bits. Recommended for solid surface applications and laminate installation. Measures 1/2″ square or upgrade to the 3/4″ B8SQ square. Both parts have a standard 3/16″ inside diameter. How does it work? The square bearing stops spinning as soon as it touches the workpiece, and the side of the square simply slides along the workpiece edge. Compare this to a regular bearing that rolls along the edge; building up glue and residue with every turn. Plus, the square is made from a non-stick material, so it wipes clean easily, and it won’t mark your workpiece.

Scarlett ★★★★★

I was a little skeptical about the square bearing, but after using it on some cherry, I noticed zero burn marks and the bearing didn't gum up at all. The 3/16″ inner diameter fit my bit perfectly, and it's noticeably smoother than the round one it replaced.

Avery ★★★★★

The square profile is a huge upgrade—it keeps the workpiece cleaner and doesn't leave those annoying track marks like the round ones did. Ran it through a full set of edge profiles on hard maple and the bearing spun smooth the entire time.

Sofia ★★★★★

Swapped out the standard round bearing on my pattern bit for this square one, and the workpiece comes out noticeably cleaner with no burn marks. It fits perfectly and spins just as freely as the original.
