1-1/2インチ オーバルエッジルータービット – Whiteside 1480（AstraHPコーティング）

The first time I used this bit on a piece of oak, the oval edge came out glass-smooth—no burning or tear-out at all. The AstraHP coating really does make a difference with heat, even on longer passes.

I was a bit skeptical about the coating, but after running it through some hard maple, the heat reduction was noticeable. This bit leaves a silky smooth oval edge with zero burning, even on a fast pass. Very pleased with the cut quality.

The AstraHP coating really does keep the heat down—I ran it through a full sheet of oak without any burn marks or slowing down. The 1-1/2″ cutting width made short work of a bullnose edge on a desk top, and the finish came out glass-smooth right off the bit.
