1/2吋 超長 CNC 泡棉切割銑刀 – 全長6吋

I needed a bit that could handle 6-inch thick foam without bending, and the extra length on this one is exactly what I was hoping for. It cut through multiple layers cleanly with zero flex from my router setup.

Cutting through a 4-inch block of rigid foam was a breeze with this bit, and the extra length meant I didn’t have to reposition my router mid-cut. The 1/2-inch shank kept everything stable without any wobble.

The 6-inch overall length gives me way more clearance on thick foam blocks, and the 1/2-inch shank stays rigid even when I push it through dense upholstery foam. I've been using it on my CNC for a week now, and the cuts come out clean with no melted edges, which was my biggest worry.
