مطحنة نهاية قطع عميقة متري 3.0 مم بطول قطع 20 مم

The 20mm cut length let me reach a deep pocket I couldn't get to with my other bits, and the flutes cleared chips perfectly. Cuts through aluminum like butter, no chatter at all.

I was nervous about the long flutes being too flexible, but this 3mm end mill cut a 15mm deep slot in aluminum without any chatter at all. The chip evacuation through those deep flutes was noticeably better than my usual short-flute bits.

Finally got to use this on a deep pocket job and the 20mm cut length meant I didn't have to switch tools halfway through. The 3mm diameter held up nicely without any chatter, even at full depth in aluminum.
