Infinity Tools 圓角 Shape-Up 成型刀，3/4" 孔徑

I was able to adjust the fence easily to get exactly the radius I needed, and the cut came out crisp with no tear-out. It handles beautifully on my shaper.

The 3/4" bore fit my router perfectly, and sliding the fence back to expose the top cutting surface made profiling edges a breeze. The radius it cuts is smooth and well-proportioned, exactly what I needed for rounding over hardwood.

I was impressed by how smoothly these cutters handled the corner rounding on some oak boards—the radius came out perfectly even without any burning. They’re a solid addition to my router setup for consistent profile work.
