Whiteside W-9540-44N 模板導套 – 內徑 11/32 英吋，外徑 7/16 英吋

The shoulder sits perfectly flush in the template, so the bit tracks dead center every pass. I’ve used cheaper guides that wobble, but this one locks in tight with zero play. That included lineup pin is a nice touch for getting the setup dialed in fast.

This bushing fit perfectly into my template and the included line-up pin made centering it a breeze. The 11/32″ inner diameter tracks my bit with no wiggle at all, which is exactly what I needed for precise joinery.

The alignment pin made setup straightforward, and the bushing fits snugly into my template without any wobble. Would have liked a storage case included for the price, but the machining quality is excellent.
