Product Overview
Engineered for high-performance finish milling and precision machining, the 45039 5-flute square end mill is made to hit that superior surface finish while still supporting extreme feed rates in finishing operations. Part of the 45000 Series Super Finisher, this tool kind of combines advanced cutting geometry with a premium solid carbide build to deliver standout accuracy, productivity, and surface quality.
The uncoated (bright finish) style keeps the cutting edges sharp and lets them act consistent across a range of materials, so you dont have to baby it. Also, the 45° high-helix geometry, helps chip evacuation move efficiently, it reduces chatter, and keeps a smooth stable cutting action for high-quality results in the end.
