ITL TV: Stop the Chatter: How End Mill Geometry Reduces Vibration
Chatter at the machine is one of the most frustrating problems a machinist can face. In this episode of In The Loupe TV, Cutting Tool Counselor Don Grandt explains how modern end mill geometry tackles the problem at its source by breaking up impact frequency.
Don walks through three key design features found on high-performance end mills: variable pitch, variable helix, and progressive helix. Each one works to disrupt the harmonic patterns that cause vibration, giving you a cleaner finish, longer tool life, and more consistent cutting action.
If you’re still running symmetrical end mills for finish work, this is the episode that will change how you spec your tools.
