1/2インチ 3枚刃 フラッシュトリムルータービット – 1/4インチシャンク – Whiteside 2500

I was surprised how cleanly this bit cut through some maple plywood—the three flutes really help prevent burning on the edges. The 1/4-inch shank fit securely in my compact router without any wobble, which made flush-trimming drawer fronts feel effortless.

The three-flute design makes trimming so much smoother than the two-flute bits I’ve used before, and the 1/4″ shank fits my router perfectly. Cuts are clean and I didn’t see any burning even on a longer pass.

The 1/4″ shank fit my compact router without any adapter fuss, and the three-flute geometry tore through an oak edge with zero chatter. Finish came out so clean I barely needed sanding, which never happens with my old bits.
