5/16インチ ラウンドオーバービット – Whiteside 2002（AstraHPコーティング）

The coating on this bit makes the wood feel almost glass-smooth after routing, and it's held up well through a dozen cabinet doors without any burning. Clean edges every time, exactly what I needed for my molding project.

The AstraHP coating really does its job—I ran this bit through some gnarly glued-up plywood edges and it still cuts like it’s fresh out of the box. Those rounded corners on my shelving came out glass-smooth with zero burn marks, even on the last pass.

Waited months for my cabinet project to finally come together, and this bit made the rounding effortless on both oak and MDF—the coated edge stayed smooth through every pass. Cuts clean, no burning, exactly what I needed for the trim work.
