Product Overview
Engineered for high-performance finish milling and precision machining, the 45038-ALTiN 5-flute square end mill is engineered to help you reach a really nice surface finish while still handling extreme feed rates during finishing work. Being in the 45000 Series Super Finisher, it mixes advanced cutting geometry with a premium solid carbide build, so you get solid accuracy, better productivity, and surface quality that holds up in the real world.
The ALTiN, meaning Aluminum Titanium Nitride, coating gives great heat resistance, strong wear protection, and a longer runtime on the tool—so it stays useful in high-speed machining and in tough production settings too. Also, the 45° high-helix geometry helps with chip evacuation and it reduces vibration, which leads to smoother, steadier cutting action for those clean finishing outcomes.
