JS & FUJI BC CO., Ltd. insert tip consists of a cutting edgeof pure diamond with no binder.
Js & FUJI BC CO., Ltd. insert can provide a wear life 3 to 4x that of PCD, and maintain edge sharpness longer.

Absence of binder avoids chemical interaction with coolant or workpiece materials, eliminating premature failure due to edge erosion. The high thermal conductivity of pure diamond dissipates heat in the cutting zone to maintain lower cutting temperatures.
In addition, the reduced cutting force of diamond lessens spindle power
