Whiteside W-9540-38N 模板導套 – 內徑 9/32 英吋，外徑 3/8 英吋

The fit is so precise that my router bit stays dead center in every template I use. The included alignment pin made setup a breeze, and the machining looks flawless up close.

I was worried these bushings might wobble during use, but the precise machining keeps the bit perfectly centered in the jig. The included line-up pin makes setup for template routing quick and accurate.

The line-up pin is a nice touch—it made seating the bushing in my template dead simple on the first try. Machining is clean and the fit in the router base is snug with zero wobble. Exactly what I needed for precise edge work.
