طقم قواطع نهاية، 6 قطع 2 سن، كوبالت

I didn't realize how much smoother a 2-flute design would cut in my mini mill compared to my old 4-flute bits. The 3/8 shanks on the smaller sizes feel much more solid than I expected too.

These cobalt end mills handled some tough stainless steel in my mini mill without any chipping. The two-flute design cleared chips nicely on the 3/8 inch shank sizes too.

The smaller end mills with the 3/8 inch shanks fit my mini mill's collet without any adapters, which saved me a good chunk of setup time. Cobalt's held an edge through a batch of stainless screws without any chatter, and the two-flute design clears chips like a dream.
