1.7mm Metric Square End Mill

Used these for milling some tight slots in aluminum and the 1.7mm cut exactly to size on the first pass. The micrograin carbide held up really well at high spindle speeds, no chipping at all.

Milling tiny slots for a precision part today, and this 1.7mm solid carbide tip held its edge beautifully across a dozen passes in aluminum. The two-flute design cleared chips without clogging, which is exactly what I need for grooving work. Clean square corners every time, no chatter.

Finally, a 1.7mm end mill that actually cuts cleanly without chattering on my small brass parts. The micrograin carbide holds its edge noticeably longer than the cheap HSS ones I tried before.
