5/32英吋圓角雕刻刀 – Whiteside 2000D（AstraHP塗層）

I was a little skeptical about the coating making a difference, but the bit cut through maple with almost zero burning. The 5/32-inch radius gives a really clean, consistent profile on the edge.

The AstraHP coating really earns its keep—ran a full oak edge through and the bit came out clean with zero heat discoloration. That 5/32 radius leaves a crisp, even profile that needs barely any sanding afterward.

Cutting some walnut trim today and that 5/32 inch radius came out perfectly clean with no burning, even on a fast pass. The AstraHP coating definitely seems to keep it cool compared to my old uncoated bits.
