VAC Series Carbide 4-Flute Uneven Lead Square End Mill
- Volume Discount
-Demonstrates high performance when machining general steel, EN 1.4301 Equiv. (sintered) and heat-treated steel (up to 50 HRC)
-Suppresses chattering with uneven pitch and uneven flutes
-Ultra-fine particle carbide base material and coating with excellent adhesion and heat resistance are used
-Stable machining is possible while maintaining the accuracy of the finished surface
-Coating with excellent lubricity provides stable abrasion resistance and improves the shape accuracy of the workpiece (VAC coating has weak electrical conductivity. Please be careful when using an electric set-up device)
-Can be reground. Please refer to the "Regrinding Service" page for application procedures, range of services, prices, etc.

Features of VAC Unequal Leads
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

Example of Use
● High efficiency machining can be realized by suppressing chattering through the use of "unequal lead."
● Smooth chip discharge is achieved using an optimum groove geometry.
[ ! ] The electrical conductivity is minimal.
