A New and Improved Grade for the Micro Line

A tough sub-micron substrate with TiCN coating for general use, VBXprovides good fracture toughness and excellent wear resistance

Applications

New Slanted Insert DesignProvides exact insert location forhigh repeatability

Stopper PinProvides precise cuttingedge height and perfectaxial location

Improved Coolant Thru

Two coolant holes for effective chipremoval and cooling of cutting edge

Simple Clamping SystemSimple and fool-proof, the new clampingsystem uses one large screw to securethe insert in the holder
