Features of VAC Unequal Leads

VAC Series Carbide Uneven Lead End Mill for Difficult-to-Cut Materials (Regular Model):Related Image

Unequal Leads + Unequal Division = Suppressed Chatter Vibration!

Design with Features to Suppress Vibration with Readily Vibrating Objects
Clean surface finish of machined objects!

[ What are unequal leads? ]
By changing the twist angles of each cutting edge of the same end mill, attenuation of generated vibrations is encouraged which leads to suppressed chatter.

[ What are unequal divisions? ]
The periodicity of the tool vibrations when cutting are cancelled by making the divisions at the bottom of the blade unequal
