محمل لقمة الراوتر 5/8″ × قطر داخلي 1/4″ – Whiteside B6

I was hoping for a smooth fit and this bearing didn't disappoint — the inner diameter tolerance is spot-on for my 1/4-inch arbor. It spins freely with no wobble, which made trimming edges much cleaner. Definitely worth the few dollars to keep an old bit running.

The 1/4″ inner diameter fit my bit perfectly, no wobble at all once it was seated. This is the third one I've bought for different jobs, and they always spin smooth without any heat buildup during long passes.

Slipped this onto my 5/8″ bit and the 1/4″ bore locked on perfectly with no wobble during a full day of edge routing. The bearing spins smooth and quiet, just what I needed to get the old one replaced without buying a whole new bit.
