1/2吋凹弧銑刀 x 1/4吋柄 – Whiteside 1802 (AstraHP塗層)

I've been using this bit for about a month now, and the cut on poplar comes out glass-smooth every time. The 1/4-inch shank grips solidly in my router, and the coating still looks like new after several passes.

The AstraHP coating really holds up—I’ve run this bit through a dozen passes on oak and it still cuts like new, with zero burn marks. The 1/4″ shank fits my trim router perfectly, and the cove profile came out silky smooth. Worth every penny for the finish alone.

That AstraHP coating on this bit really makes a difference—cuts through oak like butter and the finish is noticeably cleaner than with my uncoated bits. The 1/4" shank fits perfectly in my trim router for smaller cove profiles.
