لقمة حلزونية للأعلى 6 مم – ساق 1/4 بوصة (مطلية بـ AstraHP)

Took a chance on this bit for a tricky project with dense hardwood, and the AstraHP coating definitely helps keep the heat down during long runs. The up-cut spiral pulls chips out perfectly, leaving smooth edges that need almost no sanding.

The 6mm diameter fits perfectly in my CNC collet, and the up-cut design lifted chips out of the cut without clogging. Managed a full hour of continuous routing in hardwood with zero dulling.

The AstraHP coating really holds up—after a full day of pocketing, the flutes still look sharp and the edges came out clean with zero fuzz. It's pricier than my old bits, but the durability makes it worth every cent.
