Product Overview
Engineered for high-performance finish milling , and precision machining needs, the 45039-ALTiN 5-flute square end mill i s made to chase superior surface finishes while keeping extreme feed rates during those finishing passes. It’s part of the 45000 Series Super Finisher, so the tool blends advanced cutting geometry with a premium solid carbide body, which helps it deliver accurate results, strong productivity, and really solid surface quality.
The ALTiN , (Aluminum Titanium Nitride) coating brings excellent heat resistance, great wear protection, and a longer service life too, so it works well for high speed machining plus tougher production situations. Also the 45° high helix geometry helps with chip evacuation, lowers vibration, and keeps the cut feeling smooth and consistent, which is what you want for high quality finishing outcomes.
