RECOMMENDED APPL ICAT ION TYPES
The WK-6 Series has been designed
as a material specific cutter, providing
superior performance while machining
Titanium.
GEN2 withMicro EdgeProcess
SAME WHISPERKUT®
TECHNOLOGY BUTWITH A NEW TWIST
Our WhisperKut GEN2 Series end mills arebased on the same patented technology of ourpopular WhisperKut end mills but with the additionof a controlled micro edge process. Dura-Mill’s Micro Edge process enhances edge
stability and minimizes the tendency of prematureedge chipping resulting in consistently superior tool performance. Additionally, GEN2 end mills are produced from
a premium sub micro grain carbide specifically designed for machining Titanium.
BENEFITS
• up to 100% tool lifeimprovement
• Stronger and smoother cuttingedges
• Improved surface foundation for betteradhesion of PVD coating
• Leaves work piece surface exceptionallysmooth
• Provides predictabletool life
• Homogenous cuttingsurface prevents premature notch wear
