Dura-Mill’s new WhisperKut 6 Flute Carbide End Mill

Radial DOC (ae) = 0.2 x D

Axial DOC (ap) = 1.25 x D

Axial DOC (ap) = up to 2 x D

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

BEFORE

CUTTING EDGE

All GEN2 end mills undergo a micro-polishprocess to enhance chipflow while reducing surface friction.
