1/8″ 半徑溝槽刀 – Whiteside 3185 (AstraHP 塗層)

I was a bit skeptical about the coating, but this bit glided through some hard maple like it was butter—zero burning. The 1/8-inch radius cut a clean, consistent bead on the first pass.

Used this to cut a bead on a walnut picture frame and the profile came out crisp with almost no sanding needed. The 1/8 inch radius is perfect for small decorative edges, and it didn't burn the wood even on a slower pass.

The AstraHP coating really does keep this thing slicing clean after a few hundred feet of oak, no burn marks at all. The 1/8 radius gives a nice tight bead that matches my existing trim almost perfectly.
