Product Overview
Made for high-performance finish milling and precision machining, the 45027-ALTiN 5-flute square end mill aims to get you better surface finishes, while also supporting really extreme feed rates when you’re running finishing work. It comes from the 45000 Series Super Finisher line, and it brings together some advanced cutting geometry with a premium solid carbide body so you can get really solid accuracy, faster throughput, and good surface quality too. The ALTiN (Aluminum Titanium Nitride) coating gives standout heat resistance; it boosts wear protection and helps extend tool life, so it fits well with high-speed machining and those tough production schedules. Also, the 45° high helix shape helps with chip evacuation, keeps vibration lower, and helps you get a smooth, steady cutting action overall.
