They are preferred by Precision Tool Rooms, Engineering Industries and Research

Laboratories because of their following outstanding advantages.

No rust, no corrosion, relatively warp-free, no compensating hump when nicked,

longer wear, smoother action, greater precision, non magnetic, less care after

commissioning, lower co-efficient of thermal expansion and non glaring surface.
