Why the 30° Helix Angle Makes Milling Smoother
The 30° helix angle on this end mill is like the perfect spiral staircase—it gently guides chips away from the cutting area, preventing clogging and reducing heat. Imagine trying to sweep dirt with a flat broom versus a broom angled just right for easy pickup—this helix angle works kind of like that, making your milling experience smoother and your tools last longer.
