VAC Series Carbide 4-Flute Uneven Lead Square End Mill (VAC-VHEM4R20)
- Volume Discount
[Features]
·Demonstrates high performance in processing general steel, SUS304, and heat-treated steel (up to 50 HRC)
·Suppresses chattering with unequal lead and unequal flutes
·Ultra-fine particle cemented carbide base material and coating with excellent adhesion and heat resistance are adopted
·Stable machining is possible while maintaining finished surface accuracy
·Coating with excellent lubricity provides stable abrasion resistance and improves shape accuracy of workpiece (VAC coating has weak electrical conductivity. Please be careful when using an electrical tool setter.)
·Can be regrinded. Please refer to the page dedicated to "regrinding service" for usage 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

| Number of revolutions | 4100min-1 | Feed | 430mm/min | Cut Volume | Ad:9mm Rd:0.3mm |
- [ Chatter Vibration Comparison ]
- Drastically reduced tool vibration by adopting unequal leads / unequal divisions. Capable of even more stable machining

Example
● 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.
