Outstanding Wear Resistance Enables
Stable Machining of Heat Resistant
Super Alloys

Features

(Al, Ti, Si) N-based Coating

The (Al, Ti, Si) based coatings maintain their film hardness and heat resistant properties under the harshest of conditions making it highly suitable for applying to end mills for machining heat resistant super alloys.

New Cutting Edge Geometry

The corner radius cutting edge rake angles have been optimised for consistent contact. Additionally the structure of both the 2 and 4 flutes have been strengthened.

Versatile 4 Flute Type

When compared to 2-flute types, end mills with 4 flutes have a longer tool life and provide higher efficiency machining. In addition the new types have a much improved chip disposal rate to prevent clogging.
Now available is the new VQN4MBF with a full 4-flute end geometry, ideal for 5 axis machining. The new VQN4MB, with 4 side flutes displays a special end geometry with only 2 flutes, designed with extra space for excellent chip evacuation during rough machining.

Cutting Performance

Machining Inconel 718 - Comparison of Fracture Resistance

Cutting time has been reduced due to an increased feed rate and an excellent resistance to fracturing during slotting.
Ideal for machining heat resistant alloys typically used in the aerospace industry.
