Infinity Tools 1/2 英吋柄圓鼻銑刀（附軸承）

I was worried about chatter with a 1/2" shank bit, but this one cuts smoothly through hard maple without any vibration. The bearing guide makes it easy to follow a template for perfect, consistent coves every time.

I’ve been using this roundnose bit for making decorative grooves in maple, and the bearing follows the template perfectly—no slipping at all. The cut is smooth and clean right out of the box.

Took a scrap oak board and ran this bit along the inside edge — the cove came out perfectly smooth with zero tear-out. The bearing rides true and the cut stays clean even on longer passes, which is exactly what I needed for a delicate groove detail.
