لقمة توجيه مستقيمة 5/16″ × طول القطع 1″ – Leigh #140 – Whiteside 1020 (مُطلية بـ AstraHP)

Took a deep pass through some hard maple and the Astra coating really kept the bit cool—no burn marks at all. The 1-inch cutting depth was exactly what I needed for these jig templates.

Cuts through oak like butter and the 1-inch length of cut gave me plenty of depth for my dados. The coating seems to be holding up well, no burning or pitch buildup after a solid afternoon of routing.

The AstraHP coating on this bit is the real deal—it slides through the work without any burn marks, even on a slower feed. The 1″ cut length handled my dado passes in two clean runs, and it came out of the collet still looking factory-fresh.
