Product Overview
The 45028-ALTiN 5-flute square end mill is engineered for those high-performance finish milling and precision machining jobs, where you really want that clean final surface and stable cuts while running pretty extreme feed rates. In the 45000 Series Super Finisher lineup, this tool blends advanced cutting geometry with a premium solid carbide build, so you can expect strong accuracy, good productivity, and better surface quality all at once. Now the ALTiN, short for Aluminum Titanium Nitride, is there for a reason: it delivers top heat resistance, stronger wear protection, and longer service life. That makes it a solid fit for high-speed machining as well as tough production schedules. And the 45° high-helix design helps with chip evacuation; it reduces vibration, and it keeps the cutting action smooth and consistent, so the finishing results come out right, again and again.
