بت نصف دائري 1/2 بوصة × ساق 1/4 بوصة – Whiteside 1428 (مطلي بـ AstraHP)

I’ve been cutting a lot of bullnose profiles for cabinet door edges, and the AstraHP coating on this bit really helps keep it cooler during longer runs. Cuts are clean with no burn marks.

The 1/4-inch shank fits my trim router perfectly, and the half-round profile came out silky smooth on a piece of oak—no burning or tear-out even at a decent feed rate. I’ve used cheaper bits that left fuzz, but this one cut like it was greased, and the coating still looks brand new after a dozen pas

The AstraHP coating truly shines here—it pushed through a dozen oak edge-routing passes without any burn marks or buildup. The 1/2-inch cutting diameter gives a clean, consistent bullnose profile that needed barely any sanding afterward.
