Henry G. ★★★★★

I was dreading having to buy a whole new bit just because the bearing wore out, but this replacement popped right on and spins true. The 1/4″ inner diameter seated perfectly on the shaft, zero wobble.

Steven J. ★★★★★

The 1/2″ outer diameter fits perfectly on my Whiteside bits, and the 1/4″ inner bore slides on without any play. It spins true and smooth—exactly what I needed to get back to work on my drawer fronts.

Alexander ★★★★★

Precision-machined to the point where it spun true with zero wobble on my existing bit—exactly what I needed for a clean, flush trim. The 1/2-inch OD seated snugly against the guide bushing, and it’s held up through a solid afternoon of oak without heating up. Glad I grabbed this as a spare.
