لقمة توجيه مستقيمة 3/8″ × 1-1/4″ طول القطع × 3/8″ ساق – Whiteside 1040 (مطلية AstraHP)

Running this through a full sheet of maple plywood and the finish is glass-smooth right out of the box. The AstraHP coating really cuts down on heat—no burn marks at all after three hours of heavy use.

Wish I'd tried an AstraHP-coated bit sooner—the reduced heat and longer edge life made routing this batch of door panels a breeze. Even at full 1-1/4″ depth, it cut clean without any burning or chatter.

I’ve been using this bit for a few days now, and the 1-1/4″ length of cut handles deep dados without any noticeable burning on hard maple. The AstraHP coating really does keep the edges sharp longer than my old uncoated bits, so I’m already planning a second one for the shop.
