Infinity Tools 1/2インチシャンク ブルノーズルータービット

Two passes with my old bits and still got chatter marks, but this bearing-guided bullnose made smooth work of a solid oak shelf in one single pass.

I was tired of swapping bits mid-pass, so these bearing-guided bits cutting both roundovers at once saved me serious time on stair treads. The 1/2" shank felt rock-solid in my router table.

Finally, a bit that makes bullnose edges look professional on the first try. I used it for a window sill and the double-roundover pass saved me a ton of setup time. The bearing guide tracked smoothly along the template without any chatter.
