Infinity Tools 1/2インチシャンク ラウンドノーズルータービット

The smooth finish from these bits is exactly what I needed for my bowl project. They cut cleanly through the walnut without burning, and the 1/2" shank gave me zero vibration even at high speeds.

I was nervous about tear-out on a tricky piece of walnut, but the roundnose bit carved a perfect, glass-smooth cove on the first pass. It handles the interior edges of bowls just as cleanly, which saved me a ton of sanding time.

Finally a bit that cuts cleanly through oak without any burning. The cove it leaves is so smooth I barely had to sand before finishing.
