1/2英吋鑰匙孔銑刀 x 1/2英吋柄 – Whiteside 3053

I was pleasantly surprised by how cleanly this bit cut the keyhole slots for my jig. The 1/2-inch cutting diameter worked perfectly, and the shank held steady in my router with no vibration at all.

The 1/2-inch shank gives this bit a rock-solid grip in my router, and the cutting diameter leaves a clean slot that my hanging hardware seats into flush every time. It’s become my go-to for cabinet backs, and I’ve already run it through a dozen oak panels without any wobble or burn marks.

The Whiteside 3053 bit fits perfectly in my router and makes keyhole slots with zero tear-out on oak. I was surprised how smoothly it cut even with the grain.
