90° V型溝槽銑刀 x 直徑0.75吋 x 柄徑1/2吋 – Whiteside 1504（AstraHP塗層）

The 3/8″ point length on this bit gives me just the right depth for clean chamfers on oak. It’s held up well through a dozen passes on plywood without any dulling.

That 90° v-bit cut through acrylic like butter, leaving a perfectly smooth, chip-free groove on the first pass. The Astra coating really seems to help with heat buildup during longer runs.

Used it to chamfer some oak edges and then tried it on acrylic – the 90° point left a crisp, mirror-like groove on both with zero chipping. The 1/2" shank runs true in the router table, no vibration even at full depth. This bit's earned a permanent spot in my drawer.
