لقمة حلزونية للقطع السفلي 5 مم – ساق 1/4″ (مطلية بـ AstraHP)

The AstraHP coating really pulls its weight here—my spindle runs noticeably cooler even after an hour of continuous pocketing, and the bit stays sharp. Edges on my plywood parts came out clean with zero tear-out on the top surface, which is exactly what I needed for a client-facing job.

Finally a down-cut bit that actually leaves zero chip-out on my plywood edges. The AstraHP coating really seems to make a difference, as the bit ran noticeably cooler than my uncoated ones. I've already ordered a second size.

Ran it through a full sheet of plywood with zero tear-out on the top surface, and the AstraHP coating definitely kept the heat down even on the last pass. The 5mm diameter with the 1/4″ shank is a solid combo for detail work, and the bit still feels sharp afterward.
