لقمة توجيه مستقيمة 3/4″ × 3/4″ طول القطع – Whiteside 1030 (مطلية AstraHP)

I was worried about tear-out on some knotty oak, but this bit cuts like it's going through butter—the edge is still razor-sharp after a long afternoon of production work.

That AstraHP coating is a game changer—the bit pushes through oak without any gumming up, and the 3/4-inch cut depth handled my dados in a single pass. I've used it on a dozen projects and the edge is still razor sharp.

My old bit started leaving burn marks on oak, but this AstraHP coated one stays cool and cuts cleanly even after several passes. The carbide seems to hold an edge much longer than standard bits I've used.
