Technical overview

Geometry

Helix geometry varies over length of flutes
Variable flute design helps with chip evacuation in slots and pockets

(The combination of an extended flute length with a weldon flat may cause the flute length to reach inside some end mill holders)

Construction

Solid submicron grain carbide end mill - center cutting

PCT (Polish Carbide Treatment) enhances tool life

Coating and finish

Variable Helix - Corner Radius - 4 Flutes - AlCrN Coated

Configuration notes

Smaller diameters can be modified with a flat within 48 hours

Tolerances

flute dia. +.000-.002" (+.000-.050mm) · shank dia. h6 · radius +.001-.001" (+0.025-0.025mm)
